Merge remote-tracking branch 'tint/main' into HEAD

- Significant post-merge cleanup needed

+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, or to ban temporarily or permanently any
+contributor for other behaviors that they deem inappropriate, threatening,
+offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+This Code of Conduct also applies outside the project spaces when the Project
+Steward has a reasonable belief that an individual's behavior may have a
+negative impact on the project or its community.
+
+## Conflict Resolution
+
+We do not believe that all conflict is bad; healthy debate and disagreement
+often yield positive results. However, it is never okay to be disrespectful or
+to engage in behavior that violates the project’s code of conduct.
+
+If you see someone violating the code of conduct, you are encouraged to address
+the behavior directly with those involved. Many issues can be resolved quickly
+and easily, and this gives people more control over the outcome of their
+dispute. If you are unable to resolve the matter for any reason, or if the
+behavior is threatening or harassing, report it. We are dedicated to providing
+an environment where participants feel welcome and safe.
+
+Reports should be directed to David Neto <dneto@google.com>, the
+Project Steward(s) for Tint. It is the Project Steward’s duty to
+receive and address reported violations of the code of conduct. They will then
+work with a committee consisting of representatives from the Open Source
+Programs Office and the Google Open Source Strategy team. If for any reason you
+are uncomfortable reaching out the Project Steward, please email
+opensource@google.com.
+
+We will investigate every complaint, but you may not receive a direct response.
+We will use our discretion in determining when and how to follow up on reported
+incidents, which may range from not taking action to permanent expulsion from
+the project and project-sponsored spaces. We will notify the accused of the
+report and provide them an opportunity to discuss it before any action is taken.
+The identity of the reporter will be omitted from the details of the report
+supplied to the accused. In potentially harmful situations, such as ongoing
+harassment or threats to anyone's safety, we may take action without notice.
+
+## Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
+available at
+https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+# How to Contribute
+
+We'd love to accept your patches and contributions to this project. There are
+just a few small guidelines you need to follow.
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution;
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to <https://cla.developers.google.com/> to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code reviews
+
+All submissions, including submissions by project members, require review. We
+use [Dawn's Gerrit](https://dawn-review.googlesource.com/) for this purpose.
+
+Submissions should follow the [Tint style guide](docs/tint/style_guide.md).
+
+## Pushing to Gerrit
+
+Each change requires a `Change-Id` field in the commit message, which is generated by the [Gerrit commit-msg hook](](https://gerrit-review.googlesource.com/Documentation/cmd-hook-commit-msg.html)). \
+In a bash terminal, with the current path set to your tint source tree, this can be obtained by running the following:
+
+```bash
+f=`git rev-parse --git-dir`/hooks/commit-msg ; mkdir -p $(dirname $f) ; curl -Lo $f https://gerrit-review.googlesource.com/tools/hooks/commit-msg ; chmod +x $f
+```
+
+If you've already locally committed a change without the `Change-Id`, running `git commit --amend` will add the missing `Change-Id`.
+
+To create a Gerrit change for review, type:
+
+```bash
+git push origin HEAD:refs/for/main
+```
+
+## Community Guidelines
+
+This project follows
+[Google's Open Source Community Guidelines](https://opensource.google.com/conduct/).

+
+### Compiling using gn + ninja
+```sh

+
+### Fuzzers on MacOS
+If you are attempting fuzz, using `TINT_BUILD_FUZZERS=ON`, the version of llvm

+
+The build error that you will see from using the XCode SDK will look something

+```
+
+The solution to this problem is to use a full version llvm, like what you would
+get via homebrew, `brew install llvm`, and use something like `CC=<path to full
+clang> cmake ..` to setup a build using that toolchain.
+
+### Checking [chromium-style] issues in CMake builds
+The gn based work flow uses the Chromium toolchain for building in anticipation

+# Dawn, a WebGPU implementation
+
+Dawn is an open-source and cross-platform implementation of the work-in-progress [WebGPU](https://webgpu.dev) standard.
+More precisely it implements [`webgpu.h`](https://github.com/webgpu-native/webgpu-headers/blob/master/webgpu.h) that is a one-to-one mapping with the WebGPU IDL.
+Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
+
+Dawn provides several WebGPU building blocks:
+ - **WebGPU C/C++ headers** that applications and other building blocks use.
+ - The `webgpu.h` version that Dawn implements.
+ - A C++ wrapper for the `webgpu.h`.
+ - **A "native" implementation of WebGPU** using platforms' GPU APIs:
+ - **D3D12** on Windows 10
+ - **Metal** on macOS and iOS
+ - **Vulkan** on Windows, Linux, ChromeOS, Android and Fuchsia
+ - OpenGL as best effort where available
+ - **A client-server implementation of WebGPU** for applications that are in a sandbox without access to native drivers
+
+Helpful links:
+
+ - [Dawn's bug tracker](https://bugs.chromium.org/p/dawn/issues/entry) if you find issues with Dawn.

+
+## Reader
+
+Readers are responsible for parsing a shader program and populating a
+`ProgramBuilder` with the parsed AST, type and symbol information.
+
+The WGSL reader is a recursive descent parser. It closely follows the WGSL
+grammar in the naming of the parse methods.
+
+## ProgramBuilder
+
+A `ProgramBuilder` is the primary interface to construct an immutable `Program`.
+There are a number of methods exposed which make creating of the `Program`
+simpler. A `ProgramBuilder` can only be used once, and must be discarded after
+the `Program` is constructed.
+
+A `Program` is built from the `ProgramBuilder` by `std::move()`ing the
+`ProgramBuilder` to a new `Program` object. When built, resolution is performed
+so the produced `Program` will contain all the needed semantic information.
+
+At any time before building the `Program`, `ProgramBuilder::IsValid()` may be
+called to ensure the AST is **structurally** correct. This checks that things
+like `if` statements have a condition and body attached.
+
+If further changes to the `Program` are needed (say via a `Transform`) then a
+new `ProgramBuilder` can be produced by cloning the `Program` into a new
+`ProgramBuilder`.
+
+Unlike `Program`s, `ProgramBuilder`s are not part of the public Tint API.
+
+## AST
+
+The Abstract Syntax Tree is a directed acyclic graph of `ast::Node`s which
+encode the syntactic structure of the WGSL program.
+
+The root of the AST is the `ast::Module` class which holds each of the declared
+functions, variables and user defined types (type aliases and structures).
+
+Each `ast::Node` represents a **single** part of the program's source, and so
+`ast::Node`s are not shared.
+
+The AST does not perform any verification of its content. For example, the
+`ast::StrideAttribute` node has numeric stride parameter, which is a count of
+the number of bytes from the start of one array element to the start of the
+next. The AST node itself does not constrain the set of stride values that you
+can set, aside from storing it as an unsigned integer.
+
+## Types
+
+Types are constructed during the Reader and resolution phases, and are
+held by the `Program` or `ProgramBuilder`. AST and semantic nodes can both
+reference types.
+
+Each `type::Type` node **uniquely** represents a particular spelling of a WGSL
+type within the program, so you can compare `type::Type*` pointers to check for
+equivalence of type expressions.
+For example, there is only one `type::Type` node for the `i32` type, no matter
+how many times it is mentioned in the source program.
+However, if `MyI32` is a type alias for `i32`, then they will have two different
+type nodes.
+
+## Semantic information
+
+Semantic information is held by `sem::Node`s which describe the program at
+a higher / more abstract level than the AST. This includes information such as
+the resolved type of each expression, the resolved overload of a builtin
+function call, and the module scoped variables used by each function.
+
+Semantic information is generated by the `Resolver` when the `Program`
+is built from a `ProgramBuilder`.
+
+The `sem::Info` class holds a map of `ast::Node`s to `sem::Node`s.
+This map is **many-to-one** - i.e. while a AST node might have a single
+corresponding semantic node, the reverse may not be true. For example:
+many `ast::IdentifierExpression` nodes may map to a single `sem::Variable`,
+and so the `sem::Variable` does not have a single corresponding
+`ast::Node`.
+
+Unlike `ast::Node`s, semantic nodes may not necessarily form a directed acyclic
+graph, and the semantic graph may contain diamonds.
+
+## Symbols
+
+Symbols represent a unique string identifier in the source program. These string
+identifiers are transformed into symbols within the `Reader`s.
+
+During the Writer phase, symbols may be emitted as strings using a `Namer`.
+A `Namer` may output the symbol in any form that preserves the uniqueness of
+that symbol.
+
+## Resolver
+
+The `Resolver` will automatically run when a `Program` is built.
+A `Resolver` creates the `Program`s semantic information by analyzing the
+`Program`s AST and type information.
+
+The `Resolver` will validate to make sure the generated `Program` is
+semantically valid.
+
+## Program
+
+A `Program` holds an immutable version of the information from the
+`ProgramBuilder` along with semantic information generated by the
+`Resolver`.
+
+Like `ProgramBuilder`, `Program::IsValid()` may be called to ensure the AST is
+structurally correct and semantically valid, and that the `Resolver` did not
+report any errors.
+
+Unlike the `ProgramBuilder`, a `Program` is fully immutable, and is part of the
+public Tint API. The immutable nature of `Program`s make these entirely safe
+to share between multiple threads without the use of synchronization primitives.
+
+## Inspector
+
+The inspectors job is to go through the `Program` and pull out various pieces of
+information. The information may be used to pass information into the downstream
+compilers (things like specialization constants) or may be used to pass into
+transforms to update the AST before generating the resulting code.
+
+The input `Program` to the inspector must be valid (pass validation).
+
+## Transforms
+
+There maybe various transforms we want to run over the `Program`.
+This is for things like Vertex Pulling or Robust Buffer Access.
+
+A transform operates by cloning the input `Program` into a new `ProgramBuilder`,
+applying the required changes, and then finally building and returning a new
+output `Program`. As the resolver is always run when a `Program` is built,
+Transforms will always emit a `Program` with semantic information.
+
+The input `Program` to a transform must be valid (pass validation).
+If the input `Program` of a transform is valid then the transform must guarantee
+that the output program is also valid.
+
+## Writers
+

+# Generating and viewing Tint code-coverage
+
+Requirements:
+
+* Host running Linux or macOS
+* Clang toolchain on the `PATH` environment variable
+
+## Building Tint with coverage generation enabled
+
+Follow the steps [to build Tint with CMake](../README.md), but include the additional `-DTINT_EMIT_COVERAGE=1` CMake flag.
+
+## Generate coverage information
+
+Use the `<tint>/tools/tint-generate-coverage` script to run the tint executable or unit tests and generate the coverage information.
+
+The script takes the executable to invoke as the first command line argument, followed by additional arguments to pass to the executable.
+
+For example, to see the code coverage for all unit tests, run:
+`<tint>/tools/tint-generate-coverage <build>/tint_unittests --gtest_brief`
+
+The script will emit two files at the root of the tint directory:
+
+* `coverage.summary` - A text file giving a coverage summary for all Tint source files.
+* `lcov.info` - A binary coverage file that can be consumed with the [VSCode Coverage Gutters](https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters) extension.

+# Tint diagnostic style guide
+
+This guide provides a set of best practices when writing code that emits
+diagnostic messages in Tint. These diagnostics are messages presented to the
+user in case of error or warning.
+
+The goal of this document is to have our diagnostic messages be clear and
+understandable to our users, so that problems are easy to fix, and to try and
+keep a consistent style.
+
+## Message style
+
+* Start diagnostic messages with a lower-case letter
+* Try to keep the message to a single sentence, if possible
+* Do not end the message with punctuation (full stop, exclamation mark, etc)
+
+**Don't:**
+
+```
+shader.wgsl:7:1 error: Cannot take the address of expression.
+```
+
+**Do:**
+
+```
+shader.wgsl:7:1 error: cannot take the address of expression
+```
+
+**Justification:**
+
+Succinct messages are more important than grammatical correctness. \
+This style matches the style found in most other compilers.
+
+## Prefer to use a `Source` location instead of quoting the code in the message
+
+**Don't:**
+
+```
+shader.wgsl:5:7 error: cannot multiply 'expr_a * expr_b' with types i32 and f32
+
+var res : f32 = expr_a * expr_b
+ ^^^^^^^^^^^^^^^
+```
+
+**Do:**
+
+```
+shader.wgsl:5:7 error: cannot multiply types i32 and f32
+
+var res : f32 = expr_a * expr_b
+ ^^^^^^^^^^^^^^^
+```
+
+**Justification:**
+
+The highlighted line provides even more contextual information than the quoted
+source, and duplicating this information doesn't provide any more help to the
+developer. \
+Quoting single word identifiers or keywords from the source is not discouraged.
+
+## Use `note` diagnostics for providing additional links to relevant code
+
+**Don't:**
+
+```
+shader.wgsl:5:11 error: type cannot be used in storage class 'storage' as it is non-host-shareable
+
+ cond : bool;
+ ^^^^
+```
+
+**Do:**
+
+```
+shader.wgsl:5:11 error: type cannot be used in storage class 'storage' as it is non-host-shareable
+
+ cond : bool;
+ ^^^^
+
+shader.wgsl:8:4 note: while instantiating variable 'StorageBuffer'
+
+var<storage> sb : StorageBuffer;
+ ^^
+```
+
+**Justification:**
+
+To properly understand some diagnostics requires looking at more than a single
+line. \
+Multi-source links can greatly reduce the time it takes to properly
+understand a diagnostic message. \
+This is especially important for diagnostics raised from complex whole-program
+analysis, but can also greatly aid simple diagnostics like symbol collision errors.
+
+## Use simple terminology
+
+**Don't:**
+
+```
+shader.wgsl:7:1 error: the originating variable of the left-hand side of an assignment expression must not be declared with read access control.
+```
+
+**Do:**
+
+```
+shader.wgsl:7:1 error: cannot assign to variable with read access control
+
+x.y = 1;
+^^^^^^^
+
+shader.wgsl:2:8 note: read access control declared here
+
+var<storage, read> x : i32;
+ ^^^^
+```
+
+**Justification:**
+
+Diagnostics will be read by Web developers who may not be native English
+speakers and are unlikely to be familiar with WGSL specification terminology.
+Too much technical jargon can be intimidating and confusing. \
+Diagnostics should give enough information to explain what's wrong, and most
+importantly, give enough information so that a fix actionable.
+
+**Caution:** Be careful to not over simplify. Use the specification terminology
+if there's potential ambiguity by not including it.

+# Tint end-to-end tests
+
+This repo contains a large number of end-to-end tests at `<tint>/test`.
+
+## Test files
+
+Test input files have either the `.wgsl`, `.spv` or `.spvasm` file extension.
+
+Each test input file is tested against each of the Tint backends. There are `<number-of-input-files>` × `<number-of-tint-backends>` tests that are performed on an unfiltered end-to-end test run.
+
+Each backend test can have an **expectation file**. This expectation file sits next to the input file, with a `<input-file>.expected.<format>` extension. For example the test `test/foo.wgsl` would have the HLSL expectation file `test/foo.wgsl.expected.hlsl`.
+
+An expectation file contains the expected output of Tint, when passed the input file for the given backend.
+
+If the first line of the expectation file starts `SKIP`, then the test will be skipped instead of failing the end-to-end test run. It is good practice to include after the `SKIP` a reason for why the test is being skipped, along with any additional details, such as compiler error messages.
+
+## Running
+
+To run the end-to-end tests use the `<tint>/test/test-all.sh` script, passing the path to the tint executable as the first command line argument.
+
+You can pass `--help` to see the full list of command line flags.\
+The most commonly used flags are:
+
+| flag | description |
+|----------------------|-------------|
+|`--filter` | Filters the testing to subset of the tests. The filter argument is a glob pattern that can include `*` for any substring of a file or directory, and `**` for any number of directories.<br>Example: `--filter 'expressions/**/i32.wgsl'` will test all the `i32.wgsl` expression tests.
+|`--format` | Filters the tests to the particular backend.<br>Example: `--format hlsl` will just test the HLSL backend.
+|`--generate-expected` | Generate expectation files for the tests that previously had no expectation file, or were marked as `SKIP` but now pass.
+|`--generate-skip` | Generate `SKIP` expectation files for tests that are not currently passing.
+
+## Authoring guidelines
+
+Each test should be as small as possible, and focused on the particular feature being tested.
+
+Use sub-directories whenever possible to group similar tests, and try to keep the pattern of directories as consistent as possible between different tests. This helps filter tests using the `--filter` glob patterns.

+# Experimental extensions
+
+Sometimes a language feature proposed for WGSL requires experiementation
+to prove its worth. Tint needs to support these, in general to enable
+that experimentation.
+
+The steps for doing so are:
+
+1. Choose a name for the feature, to be used in an `enable` directive.
+ An experimental extension should use prefix of `google_experimental_`
+ Example:
+
+ enable google_experimental_f16;
+
+2. Write down what the feature is supposed to mean.
+ This informs the Tint implementation, and tells shader authors what
+ has changed.
+ Ideally, this will take the form of one of the following:
+
+ - A PR against the WGSL spec.
+
+ - A description of what the contents of that PR would be, committed
+ as a document in this Tint repository.
+
+3. File a tracking bug for adding the feature.
+ Note: Should the Tint repo have a label for experimental features?
+
+4. File a tracking bug for removing the feature or converting it to
+ non-experimental.
+
+5. Write a plan for removal of the experiment.
+ - Ideally, this plan is committed to this repository, especially the
+ description of public activities and commitments. However, we recognize
+ that some internal goals or metrics may be sensitive, and can be hidden.
+ - The plan is about process, not technical details. It should include:
+ - Who is the point of contact for this feature? The point of contact
+ is responsible when the feature causes an issue or gets in the way.
+ - What is your target date for declaring the experiment a success or
+ failure. In Chrome an experiment must be shipped or removed, in
+ finite time.
+ - What experience are you hoping to gain? Do you have target metrics?
+ - What approvals, if any, do you need from W3C? What is your plan to
+ present your case to W3C?
+ - The bug tracking removal of the experiment.

+# SPIR-V translation of shader input and output variables
+
+WGSL [MR 1315](https://github.com/gpuweb/gpuweb/issues/1315) changed WGSL so
+that pipeline inputs and outputs are handled similar to HLSL:
+
+- Shader pipeline inputs are the WGSL entry point function arguments.
+- Shader pipeline outputs are the WGSL entry point return value.
+
+Note: In both cases, a struct may be used to pack multiple values together.
+In that case, I/O specific attributes appear on struct members at the struct declaration.
+
+Resource variables, e.g. buffers, samplers, and textures, are still declared
+as variables at module scope.
+
+## Vulkan SPIR-V today
+
+SPIR-V for Vulkan models inputs and outputs as module-scope variables in
+the Input and Output storage classes, respectively.
+
+The `OpEntryPoint` instruction has a list of module-scope variables that must
+be a superset of all the input and output variables that are statically
+accessed in the shader call tree.
+From SPIR-V 1.4 onward, all interface variables that might be statically accessed
+must appear on that list.
+So that includes all resource variables that might be statically accessed
+by the shader call tree.
+
+## Translation scheme for SPIR-V to WGSL
+
+A translation scheme from SPIR-V to WGSL is as follows:
+
+Each SPIR-V entry point maps to a set of Private variables proxying the
+inputs and outputs, and two functions:
+
+- An inner function with no arguments or return values, and whose body
+ is the same as the original SPIR-V entry point.
+- Original input variables are mapped to pseudo-in Private variables
+ with the same store types, but no other attributes or properties copied.
+ In Vulkan, Input variables don't have initalizers.
+- Original output variables are mapped to pseudo-out Private variables
+ with the same store types and optional initializer, but no other attributes
+ or properties are copied.
+- A wrapper entry point function whose arguments correspond in type, location
+ and builtin attributes the original input variables, and whose return type is
+ a structure containing members correspond in type, location, and builtin
+ attributes to the original output variables.
+ The body of the wrapper function the following phases:
+ - Copy formal parameter values into pseudo-in variables.
+ - Insert a bitcast if the WGSL builtin variable has different signedness
+ from the SPIR-V declared type.
+ - Execute the inner function.
+ - Copy pseudo-out variables into the return structure.
+ - Insert a bitcast if the WGSL builtin variable has different signedness
+ from the SPIR-V declared type.
+ - Return the return structure.
+
+- Replace uses of the the original input/output variables to the pseudo-in and
+ pseudo-out variables, respectively.
+- Remap pointer-to-Input with pointer-to-Private
+- Remap pointer-to-Output with pointer-to-Private
+
+We are not concerned with the cost of extra copying input/output values.
+First, the pipeline inputs/outputs tend to be small.
+Second, we expect the backend compiler in the driver will be able to see
+through the copying and optimize the result.
+
+### Example
+
+
+```glsl
+ #version 450
+
+ layout(location = 0) out vec4 frag_colour;
+ layout(location = 0) in vec4 the_colour;
+
+ void bar() {
+ frag_colour = the_colour;
+ }
+
+ void main() {
+ bar();
+ }
+```
+
+Current translation, through SPIR-V, SPIR-V reader, WGSL writer:
+
+```groovy
+ @location(0) var<out> frag_colour : vec4<f32>;
+ @location(0) var<in> the_colour : vec4<f32>;
+
+ fn bar_() -> void {
+ const x_14 : vec4<f32> = the_colour;
+ frag_colour = x_14;
+ return;
+ }
+
+ @stage(fragment)
+ fn main() -> void {
+ bar_();
+ return;
+ }
+```
+
+Proposed translation, through SPIR-V, SPIR-V reader, WGSL writer:
+
+```groovy
+ // 'in' variables are now 'private'.
+ var<private> frag_colour : vec4<f32>;
+ var<private> the_colour : vec4<f32>;
+
+ fn bar_() -> void {
+ // Accesses to the module-scope variables do not change.
+ // This is a big simplifying advantage.
+ const x_14 : vec4<f32> = the_colour;
+ frag_colour = x_14;
+ return;
+ }
+
+ fn main_inner() -> void {
+ bar_();
+ return;
+ }
+
+ // Declare a structure type to collect the return values.
+ struct main_result_type {
+ @location(0) frag_color : vec4<f32>;
+ };
+
+ @stage(fragment)
+ fn main(
+
+ // 'in' variables are entry point parameters
+ @location(0) the_color_arg : vec4<f32>
+
+ ) -> main_result_type {
+
+ // Save 'in' arguments to 'private' variables.
+ the_color = the_color_arg;
+
+ // Initialize 'out' variables.
+ // Use the zero value, since no initializer was specified.
+ frag_color = vec4<f32>();
+
+ // Invoke the original entry point.
+ main_inner();
+
+ // Collect outputs into a structure and return it.
+ var result : main_outer_result_type;
+ result.frag_color = frag_color;
+ return result;
+ }
+```
+
+Alternately, we could emit the body of the original entry point at
+the point of invocation.
+However that is more complex because the original entry point function
+may return from multiple locations, and we would like to have only
+a single exit path to construct and return the result value.
+
+### Handling fragment discard
+
+In SPIR-V `OpKill` causes immediate termination of the shader.
+Is the shader obligated to write its outputs when `OpKill` is executed?
+
+The Vulkan fragment operations are as follows:
+(see [6. Fragment operations](https://www.khronos.org/registry/vulkan/specs/1.2/html/vkspec.html#fragops)).
+
+* Scissor test
+* Sample mask test
+* Fragment shading
+* Multisample coverage
+* Depth bounds test
+* Stencil test
+* Depth test
+* Sample counting
+* Coverage reduction
+
+After that, the fragment results are used to update output attachments, including
+colour, depth, and stencil attachments.
+
+Vulkan says:

+
+I interpret this to mean that the outputs of a discarded fragment are ignored.
+
+Therefore, `OpKill` does not require us to modify the basic scheme from the previous
+section.
+
+The `OpDemoteToHelperInvocationEXT`
+instruction is an alternative way to throw away a fragment, but which
+does not immediately terminate execution of the invocation.
+It is introduced in the [`SPV_EXT_demote_to_helper_invocation](http://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/EXT/SPV_EXT_demote_to_helper_invocation.html)
+extension. WGSL does not have this feature, but we expect it will be introduced by a
+future WGSL extension. The same analysis applies to demote-to-helper. When introduced,
+it will not affect translation of pipeline outputs.
+
+### Handling depth-replacing mode
+
+A Vulkan fragment shader must write to the fragment depth builtin if and only if it
+has a `DepthReplacing` execution mode. Otherwise behaviour is undefined.
+
+We will ignore the case where the SPIR-V shader writes to the `FragDepth` builtin
+and then discards the fragment.
+This is justified because "no further operations" are performed by the pipeline
+after the fragment is discarded, and that includes writing to depth output attachments.
+
+Assuming the shader is valid, no special translation is required.
+
+### Handling output sample mask
+
+By the same reasoning as for depth-replacing, it is ok to incidentally not write
+to the sample-mask builtin variable when the fragment is discarded.
+
+### Handling clip distance and cull distance
+
+Most builtin variables are scalars or vectors.
+However, the `ClipDistance` and `CullDistance` builtin variables are arrays of 32-bit float values.
+Each entry defines a clip half-plane (respectively cull half-plane)
+A Vulkan implementation must support array sizes of up to 8 elements.
+
+How prevalent are shaders that use these features?
+These variables are supported when Vulkan features `shaderClipDistance` and `shaderCullDistance`
+are supported.
+According to gpuinfo.org as of this writing, those
+Vulkan features appear to be nearly universally supported on Windows devices (>99%),
+but by only 70% on Android.
+It appears that Qualcomm devices support them, but Mali devices do not (e.g. Mali-G77).
+
+The proposed translation scheme forces a copy of each array from private
+variables into the return value of a vertex shader, or into a private
+variable of a fragment shader.
+In addition to the register pressure, there may be a performance degradation
+due to the bulk copying of data.
+
+We think this is an acceptable tradeoff for the gain in usability and
+consistency with other pipeline inputs and outputs.
+
+## Translation scheme for WGSL AST to SPIR-V
+
+To translate from the WGSL AST to SPIR-V, do the following:
+
+- Each entry point formal parameter is mapped to a SPIR-V `Input` variable.
+ - Struct and array inputs may have to be broken down into individual variables.
+- The return of the entry point is broken down into fields, with one
+ `Output` variable per field.
+- In the above, builtins must be separated from user attributes.
+ - Builtin attributes are moved to the corresponding variable.
+ - Location and interpolation attributes are moved to the corresponding
+ variables.
+- This translation relies on the fact that pipeline inputs and pipeline
+ outputs are IO-shareable types. IO-shareable types are always storable,
+ and can be the store type of input/output variables.
+- Input function parameters will be automatically initialized by the system
+ as part of setting up the pipeline inputs to the entry point.
+- Replace each return statement in the entry point with a code sequence
+ which writes the return value components to the synthesized output variables,
+ and then executes an `OpReturn` (without value).
+
+This translation is sufficient even for fragment shaders with discard.
+In that case, outputs will be ignored because downstream pipeline
+operations will not be performed.
+This is the same rationale as for translation from SPIR-V to WGSL AST.

+# SPIR-V translation of WGSL pointers and references
+
+WGSL was updated to have two kinds of memory views: pointers and references.
+See https://github.com/gpuweb/gpuweb/pull/1569
+
+In summary:
+
+* Reference types are never explicitly mentioned in WGSL source.
+* A use of a variable is a value of reference type corresponding
+ to the reference memory view of the storage allocated for the
+ variable.
+* Let-declared constants can be of pointer type, but not reference
+ type.
+* Function parameter can be of pointer type, but not reference type.
+* A variable's store type is never a pointer type, and never a
+ reference type.
+* The "Load Rule" allows a reference to decay to the underlying
+ store type, by issuing a load of the value in the underlying memory.
+* For an assignment:
+ * The right-hand side evaluates to a non-reference type (atomic-free
+ plain type).
+ * The left-hand side evaluates to a reference type, whose store
+ type is the same as the result of evaluating the right hand side.
+* The address-of (unary `&`) operator converts a reference to a
+ pointer.
+* The dereference (unary `*`) operator converts a pointer to a
+ reference.
+
+TODO: Passing textures and samplers to helper functions might be
+done by "handler value", or by pointer-to-handle.
+
+## Writing SPIR-V from WGSL
+
+The distinction in WGSL between reference and pointer disappears
+at the SPIR-V level. Both types map into pointer types in SPIR-V.
+
+To translate a valid WGSL program to SPIR-V:
+
+* The dereference operator (unary `*`) is the identity operation.
+* The address-of operator (unary `&`) is the identity operation.
+* Assignment maps to OpStore.
+* The Load Rule translates to OpLoad.
+
+## Reading SPIR-V to create WGSL
+
+The main changes to the SPIR-V reader are:
+
+* When translating a SPIR-V pointer expression, track whether the
+ corresponding WGSL expression is of corresponding WGSL pointer
+ type or correspoinding WGSL type.
+* Insert dereference (unary-`*`) or address-of (unary-`&`) operators
+ as needed to generate valid WGSL expressions.
+
+The choices can be made deterministic, as described below.
+
+The SPIR-V reader only supports baseline functionality in Vulkan.
+Therefore we assume no VariablePointers or VariablePointersStorageBuffer
+capabilities. All pointers are
+[SPIR-V logical pointers](https://www.khronos.org/registry/spir-v/specs/unified1/SPIRV.html#LogicalPointerType).
+The [SPIR-V Universal Validation Rules](https://www.khronos.org/registry/spir-v/specs/unified1/SPIRV.html#_universal_validation_rules)
+specify where logical pointers can appear as results of instructions
+or operands of instructions.
+
+Each SPIR-V pointer result expression is a logical pointer, and
+therefore is one of:
+
+* OpVariable: map to the reference type.
+* OpFunctionParameter: map to the pointer type.
+* OpCopyObject:
+ * When these only have one use, then these often fold away.
+ Otherwise, they map to a a let-declared constant.
+ * Map to the pointer type.
+* OpAccessChain, OpInBoundsAccessChain:
+ * This could map to either pointer or reference, and adjustments
+ in other areas could make it work. However, we recommend mapping
+ this to the reference type.
+* OpImageTexelPointer is not supported in WGSL.
+ It is used to get a pointer into a storage texture, for use with
+ atomic instructions. But image atomics is not supported in
+ WebGPU/WGSL.
+
+Each SPIR-V pointer operand is also a logical pointer, and is an
+operand to one of:
+* OpLoad Pointer operand:
+ * Map to reference, inserting a dereference operator if needed.
+* OpStore Pointer operand:
+ * Map to reference, inserting a dereference operator if needed.
+* OpStore Pointer operand:
+* OpAccessChain, OpInBoundsAccessChain Base operand:
+ * WGSL array-access and subfield access only works on references.
+ * [Gpuweb issue 1530](https://github.com/gpuweb/gpuweb/issues/1530)
+ is filed to allow those operations to work on pointers.
+ * Map to reference, inserting a dereference operator if needed.
+* OpFunctionCall function argument pointer operands
+ * Function operands can't be references.
+ * Map to pointer, inserting an address-of operator if needed.
+* OpAtomic instruction Pointer operand
+ * These map to WGSL atomic builtins.
+ * Map to pointer, inserting an address-of operator if needed.
+ * Note: As of this writing, the atomic instructions are not supported
+ by the SPIR-V reader.
+* OpCopyObject source operand
+ * This could have been mapped either way, but it's easiest to
+ map to pointer, to match the choice for OpCopyObject result type.
+ * Map to pointer, inserting an address-of operator if needed.
+* OpCopyMemory, source and destination operands
+ * This acts as an assignment.
+ * Map both source and destination to reference, inserting dereference
+ operators if needed.
+ * Note: As of this writing, OpCopyMemory is not supported by the
+ SPIR-V reader.
+* Extended instruction set instructions Modf and Frexp
+ * These map to builtins.
+ * Map the pointer operand to pointer, inserting an address-of
+ operator if needed.

+# Tint style guide
+
+* Generally, follow the [Chromium style guide for C++](https://chromium.googlesource.com/chromium/src/+/HEAD/styleguide/c++/c++.md)
+ which itself is built on the [Google C++ style guide](https://google.github.io/styleguide/cppguide.html).
+
+* Overall try to use the same style and convention as code around your change.
+
+* Code must be formatted. Use `clang-format` with the provided [.clang-format](../.clang-format)
+ file. The `tools/format` script runs the formatter.
+
+* Code should not have linting errors.
+ The `tools/lint` script runs the linter. So does `git cl upload`.
+
+* Do not use C++ exceptions
+
+* Do not use C++ RTTI.
+ Instead, use `tint::Castable::As<T>()` from
+ [src/castable.h](../src/castable.h)
+
+* Generally, avoid `assert`. Instead, issue a [diagnostic](../src/diagnostic.h)
+ and fail gracefully, possibly by returning an error sentinel value.
+ Code that should not be reachable should call `TINT_UNREACHABLE` macro
+ and other internal error conditions should call the `TINT_ICE` macro.
+ See [src/debug.h](../src/debug.h)
+
+* Use `type` as part of a name only when the name refers to a type
+ in WGSL or another shader language processed by Tint. If the concept you are
+ trying to name is about distinguishing between alternatives, use `kind` instead.
+
+## Compiler support
+
+Tint requires C++17.
+
+Tint uses the Chromium build system and will stay synchronized with that system.
+Compiler configurations beyond that baseline is on a best-effort basis.
+We strive to support recent GCC and MSVC compilers.
+
+## Test code
+
+We might relax the above rules rules for test code, since test code
+shouldn't ship to users.
+
+However, test code should still be readable and maintainable.
+
+For test code, the tradeoff between readability and maintainability
+and other factors is weighted even more strongly toward readability
+and maintainability.

+# Translations
+
+This document attempts to document how WGSL translates into the various backends
+for the cases where the translation is not a direct mapping.
+
+# Access Control
+
+## HLSL
+ * ReadOnly -> `ByteAddressBuffer`
+ * ReadWrite -> `RWByteAddressBuffer`
+
+## MSL
+ * ReadOnly -> `const`
+
+## SPIR-V
+There are two ways this can be achieved in SPIR-V. Either the variable can be
+decorated with `NonWritable` or each member of the struct can be decorated with
+`NonWritable`. We chose to go the struct member route.
+ * The read-only becomes part of the type in this case. Otherwise, you are
+ treating the readonly type information as part of the variable which is
+ confusing.
+ * Treating the readonly as part of the variable means we should be
+ deduplicating the types behind the access control, which causes confusing
+ with the type_names and various tracking systems within Tint.
