-const char* const kFuzzerHelpMessage = R"(
-This fuzzer uses SPIR-V binaries to fuzz the Tint compiler. It uses SPIRV-Tools
-to mutate those binaries. The fuzzer works on a corpus of SPIR-V shaders.
-For each shader from the corpus it uses one of `spirv-fuzz`, `spirv-reduce` or
-`spirv-opt` to mutate it and then runs the shader through the Tint compiler in
-two steps:
-- Converts the mutated shader to WGSL.
-- Converts WGSL to some target language specified in the CLI arguments.
-
-Below is a list of all supported parameters for this fuzzer. You may want to
-run it with -help=1 to check out libfuzzer parameters.
-
-Fuzzer parameters:
-
- -tint_error_dir
- The directory that will be used to output invalid SPIR-V
- binaries to. This is especially useful during debugging
- mutators. The directory must have the following subdirectories:
- - spv/ - will be used to output errors, produced during
- the conversion from the SPIR-V to WGSL.
- - wgsl/ - will be used to output errors, produced during
- the conversion from the WGSL to `--fuzzing_target`.
- - mutator/ - will be used to output errors, produced by
- the mutators.
- By default invalid files are not printed out.
-
- -tint_fuzzing_target
- The type of backend to target during fuzzing. This must
- be one or a combination of `wgsl`, `spv`, `msl` or `hlsl`
- (without `) separated by commas. By default it's
- `wgsl,spv,msl,hlsl`.
-
- -tint_help
- Show this message. Note that there is also a -help=1
- parameter that will display libfuzzer's help message.
-
- -tint_mutator_cache_size=
- The maximum size of the cache that stores
- mutation sessions. This must fit in uint32_t.
- By default it's 20.
-
- -tint_mutator_type=
- Determines types of the mutators to run. This must be one or
- a combination of `fuzz`, `opt`, `reduce` (without `) separated by
- comma. If a combination is specified, each element in the
- combination will have an equal chance of mutating a SPIR-V
- binary during a mutation session (i.e. if no mutator exists
- for that binary in the mutator cache). By default, the
- parameter's value is `fuzz,opt,reduce`.

-const char* const kMutatorDebuggerHelpMessage = R"(
-This tool is used to debug *mutators*. It uses CLI arguments similar to the
-ones used by the fuzzer. To debug some mutator you just need to specify the
-mutator type, the seed and the path to the SPIR-V binary that triggered the
-error. This tool will run the mutator on the binary until the error is
-produced or the mutator returns `kLimitReached`.
-
-Note that this is different from debugging the fuzzer by specifying input
-files to test. The difference is that the latter will not execute any
-mutator (it will only run the LLVMFuzzerTestOneInput function) whereas this
-tool is useful when one of the SPIRV-Tools mutators crashes or produces an
-invalid binary in LLVMFuzzerCustomMutator.
-
-Debugger parameters:
-
- --help
- Show this message.
-
- --mutator_type=
- Determines the type of the mutator to debug. This must be
- one of `fuzz`, `reduce` or `opt` (without `). This parameter
- is REQUIRED.
-
- --original_binary=
- The path to the SPIR-V binary that the faulty mutator was
- initialized with. This will be dumped on errors by the fuzzer
- if `--error_dir` is specified. This parameter is REQUIRED.
-
- --seed=
- The seed for the random number generator that was used to
- initialize the mutator. This value is usually printed to
- the console when the mutator produces an invalid binary.
- It is also dumped into the log file if `--error_dir` is
- specified. This must fit in uint32_t. This parameter is
- REQUIRED.

-/// ones used by the fuzzer. To debug some mutator you just need to specify the
-/// mutator type, the seed and the path to the SPIR-V binary that triggered the
-/// error. This tool will run the mutator on the binary until the error is
-/// produced or the mutator returns `kLimitReached`.
-///
-/// Note that this is different from debugging the fuzzer by specifying input
-/// files to test. The difference is that the latter will not execute any
-/// mutator (it will only run the LLVMFuzzerTestOneInput function) whereas this
-/// tool is useful when one of the spirv-tools mutators crashes or produces an
-/// invalid binary in LLVMFuzzerCustomMutator.

-/// A Variable statement.
-///
-/// An instance of this class represents one of four constructs in WGSL: "var"
-/// declaration, "let" declaration, "override" declaration, or formal parameter
-/// to a function.
-///
-/// 1. A "var" declaration is a name for typed storage. Examples:
-///
-/// // Declared outside a function, i.e. at module scope, requires
-/// // a storage class.
-/// var<workgroup> width : i32; // no initializer
-/// var<private> height : i32 = 3; // with initializer
-///
-/// // A variable declared inside a function doesn't take a storage class,
-/// // and maps to SPIR-V Function storage.
-/// var computed_depth : i32;
-/// var area : i32 = compute_area(width, height);
-///
-/// 2. A "let" declaration is a name for a typed value. Examples:
-///
-/// let twice_depth : i32 = width + width; // Must have initializer
-///
-/// 3. An "override" declaration is a name for a pipeline-overridable constant.
-/// Examples:
-///
-/// override radius : i32 = 2; // Can be overridden by name.
-/// @id(5) override width : i32 = 2; // Can be overridden by ID.
-/// override scale : f32; // No default - must be overridden.
-///
-/// 4. A formal parameter to a function is a name for a typed value to
-/// be passed into a function. Example:
-///
-/// fn twice(a: i32) -> i32 { // "a:i32" is the formal parameter
-/// return a + a;
-/// }
-///
-/// From the WGSL draft, about "var"::
-///
-/// A variable is a named reference to storage that can contain a value of a
-/// particular type.
-///
-/// Two types are associated with a variable: its store type (the type of
-/// value that may be placed in the referenced storage) and its reference
-/// type (the type of the variable itself). If a variable has store type T
-/// and storage class S, then its reference type is pointer-to-T-in-S.
-///
-/// This class uses the term "type" to refer to:
-/// the value type of a "let",
-/// the value type of an "override",
-/// the value type of the formal parameter,
-/// or the store type of the "var".
-//
-/// Setting is_const:
-/// - "var" gets false
-/// - "let" gets true
-/// - "override" gets true
-/// - formal parameter gets true
-///
-/// Setting is_overrideable:
-/// - "var" gets false
-/// - "let" gets false
-/// - "override" gets true
-/// - formal parameter gets false
-///
-/// Setting storage class:
-/// - "var" is StorageClass::kNone when using the
-/// defaulting syntax for a "var" declared inside a function.
-/// - "let" is always StorageClass::kNone.
-/// - formal parameter is always StorageClass::kNone.

-/// A structured control flow construct, consisting of a set of basic blocks.
-/// A construct is a span of blocks in the computed block order,
-/// and will appear contiguously in the WGSL source.
-///
-/// SPIR-V (2.11 Structured Control Flow) defines:
-/// - loop construct
-/// - continue construct
-/// - selection construct
-/// We also define a "function construct" consisting of all the basic blocks in
-/// the function.
-///
-/// The first block in a construct (by computed block order) is called a
-/// "header". For the constructs defined by SPIR-V, the header block is the
-/// basic block containing the merge instruction. The header for the function
-/// construct is the entry block of the function.
-///
-/// Given two constructs A and B, we say "A encloses B" if B is a subset of A,
-/// i.e. if every basic block in B is also in A. Note that a construct encloses
-/// itself.
-///
-/// In a valid SPIR-V module, constructs will nest, meaning given
-/// constructs A and B, either A encloses B, or B encloses A, or
-/// or they are disjoint (have no basic blocks in commont).
-///
-/// A loop in a high level language translates into either:
-//
-/// - a single-block loop, where the loop header branches back to itself.
-/// In this case this single-block loop consists only of the *continue
-/// construct*. There is no "loop construct" for this case.
-//
-/// - a multi-block loop, where the loop back-edge is different from the loop
-/// header.
-/// This case has both a non-empty loop construct containing at least the
-/// loop header, and a non-empty continue construct, containing at least the
-/// back-edge block.
-///
-/// We care about two kinds of selection constructs:
-///
-/// - if-selection: where the header block ends in OpBranchConditional
-///
-/// - switch-selection: where the header block ends in OpSwitch

-// Terms:
-// CFG: the control flow graph of the function, where basic blocks are the
-// nodes, and branches form the directed arcs. The function entry block is
-// the root of the CFG.
-//
-// Suppose H is a header block (i.e. has an OpSelectionMerge or OpLoopMerge).
-// Then:
-// - Let M(H) be the merge block named by the merge instruction in H.
-// - If H is a loop header, i.e. has an OpLoopMerge instruction, then let
-// CT(H) be the continue target block named by the OpLoopMerge
-// instruction.
-// - If H is a selection construct whose header ends in
-// OpBranchConditional with true target %then and false target %else,
-// then TT(H) = %then and FT(H) = %else
-//
-// Determining output block order:
-// The "structured post-order traversal" of the CFG is a post-order traversal
-// of the basic blocks in the CFG, where:
-// We visit the entry node of the function first.
-// When visiting a header block:
-// We next visit its merge block
-// Then if it's a loop header, we next visit the continue target,
-// Then we visit the block's successors (whether it's a header or not)
-// If the block ends in an OpBranchConditional, we visit the false target
-// before the true target.
-//
-// The "reverse structured post-order traversal" of the CFG is the reverse
-// of the structured post-order traversal.
-// This is the order of basic blocks as they should be emitted to the WGSL
-// function. It is the order computed by ComputeBlockOrder, and stored in
-// the |FunctionEmiter::block_order_|.
-// Blocks not in this ordering are ignored by the rest of the algorithm.
-//
-// Note:
-// - A block D in the function might not appear in this order because
-// no block in the order branches to D.
-// - An unreachable block D might still be in the order because some header
-// block in the order names D as its continue target, or merge block,
-// or D is reachable from one of those otherwise-unreachable continue
-// targets or merge blocks.
-//
-// Terms:
-// Let Pos(B) be the index position of a block B in the computed block order.
-//
-// CFG intervals and valid nesting:
-//
-// A correctly structured CFG satisfies nesting rules that we can check by
-// comparing positions of related blocks.
-//
-// If header block H is in the block order, then the following holds:
-//
-// Pos(H) < Pos(M(H))
-//
-// If CT(H) exists, then:
-//
-// Pos(H) <= Pos(CT(H))
-// Pos(CT(H)) < Pos(M)
-//
-// This gives us the fundamental ordering of blocks in relation to a
-// structured construct:
-// The blocks before H in the block order, are not in the construct
-// The blocks at M(H) or later in the block order, are not in the construct
-// The blocks in a selection headed at H are in positions [ Pos(H),
-// Pos(M(H)) ) The blocks in a loop construct headed at H are in positions
-// [ Pos(H), Pos(CT(H)) ) The blocks in the continue construct for loop
-// headed at H are in
-// positions [ Pos(CT(H)), Pos(M(H)) )
-//
-// Schematically, for a selection construct headed by H, the blocks are in
-// order from left to right:
-//
-// ...a-b-c H d-e-f M(H) n-o-p...
-//
-// where ...a-b-c: blocks before the selection construct
-// where H and d-e-f: blocks in the selection construct
-// where M(H) and n-o-p...: blocks after the selection construct
-//
-// Schematically, for a loop construct headed by H that is its own
-// continue construct, the blocks in order from left to right:
-//
-// ...a-b-c H=CT(H) d-e-f M(H) n-o-p...
-//
-// where ...a-b-c: blocks before the loop
-// where H is the continue construct; CT(H)=H, and the loop construct
-// is *empty*
-// where d-e-f... are other blocks in the continue construct
-// where M(H) and n-o-p...: blocks after the continue construct
-//
-// Schematically, for a multi-block loop construct headed by H, there are
-// blocks in order from left to right:
-//
-// ...a-b-c H d-e-f CT(H) j-k-l M(H) n-o-p...
-//
-// where ...a-b-c: blocks before the loop

-// in GLSL (and C). In GLSL and C, those forward-flow edges don't have a

-/// This is the implementation of the SPIR-V parser for Tint.
-
-/// Notes on terminology:
-///
-/// A WGSL "handle" is an opaque object used for accessing a resource via
-/// special builtins. In SPIR-V, a handle is stored a variable in the
-/// UniformConstant storage class. The handles supported by SPIR-V are:
-/// - images, both sampled texture and storage image
-/// - samplers
-/// - combined image+sampler
-/// - acceleration structures for raytracing.
-///
-/// WGSL only supports samplers and images, but calls images "textures".
-/// When emitting errors, we aim to use terminology most likely to be
-/// familiar to Vulkan SPIR-V developers. We will tend to use "image"
-/// and "sampler" instead of "handle".

+/// let twice_depth : i32 = width + width; // Must have initializer
+///
+/// 3. An "override" declaration is a name for a pipeline-overridable constant.
+/// Examples:
+///
+/// override radius : i32 = 2; // Can be overridden by name.
+/// @id(5) override width : i32 = 2; // Can be overridden by ID.
+/// override scale : f32; // No default - must be overridden.
+///
+/// 4. A formal parameter to a function is a name for a typed value to
+/// be passed into a function. Example:
+///
+/// fn twice(a: i32) -> i32 { // "a:i32" is the formal parameter
+/// return a + a;
+/// }
+///
+/// From the WGSL draft, about "var"::
+///
+/// A variable is a named reference to storage that can contain a value of a
+/// particular type.
+///
+/// Two types are associated with a variable: its store type (the type of
+/// value that may be placed in the referenced storage) and its reference
+/// type (the type of the variable itself). If a variable has store type T
+/// and storage class S, then its reference type is pointer-to-T-in-S.
+///
+/// This class uses the term "type" to refer to:
+/// the value type of a "let",
+/// the value type of an "override",
+/// the value type of the formal parameter,
+/// or the store type of the "var".
+//
+/// Setting is_const:
+/// - "var" gets false
+/// - "let" gets true
+/// - "override" gets true
+/// - formal parameter gets true
+///
+/// Setting is_overrideable:
+/// - "var" gets false
+/// - "let" gets false
+/// - "override" gets true
+/// - formal parameter gets false
+///
+/// Setting storage class:
+/// - "var" is StorageClass::kNone when using the
+/// defaulting syntax for a "var" declared inside a function.
+/// - "let" is always StorageClass::kNone.
+/// - formal parameter is always StorageClass::kNone.

+/// Switch is used to dispatch one of the provided callback case handler

+/// handlers. Switch will sequentially check the type of `object` against each
+/// of the switch case handler functions, and will invoke the first case handler
+/// function which has a parameter type that matches the object type. When a
+/// case handler is matched, it will be called with the single argument of
+/// `object` cast to the case handler's parameter type. Switch will invoke at
+/// most one case handler. Each of the case functions must have the signature
+/// `R(T*)` or `R(const T*)`, where `T` is the type matched by that case and `R`
+/// is the return type, consistent across all case handlers.
+///
+/// An optional default case function with the signature `R(Default)` can be
+/// used as the last case. This default case will be called if all previous
+/// cases failed to match.
+///
+/// If `object` is nullptr and a default case is provided, then the default case
+/// will be called. If `object` is nullptr and no default case is provided, then
+/// no cases will be called.
+///
+/// Example:
+/// ```
+/// Switch(object,
+/// [&](TypeA*) { /* ... */ },
+/// [&](TypeB*) { /* ... */ });

+/// Switch(object,

+ -tint_fuzzing_target=
+ Specifies the shading language to target during fuzzing.
+ This must be one or a combination of `wgsl`, `spv`, `hlsl`,
+ `msl` (without `) separated by commas. By default it's

+This fuzzer uses SPIR-V binaries to fuzz the Tint compiler. It uses SPIRV-Tools
+to mutate those binaries. The fuzzer works on a corpus of SPIR-V shaders.
+For each shader from the corpus it uses one of `spirv-fuzz`, `spirv-reduce` or
+`spirv-opt` to mutate it and then runs the shader through the Tint compiler in
+two steps:
+- Converts the mutated shader to WGSL.
+- Converts WGSL to some target language specified in the CLI arguments.
+
+Below is a list of all supported parameters for this fuzzer. You may want to
+run it with -help=1 to check out libfuzzer parameters.
+
+Fuzzer parameters:
+
+ -tint_error_dir
+ The directory that will be used to output invalid SPIR-V
+ binaries to. This is especially useful during debugging
+ mutators. The directory must have the following subdirectories:
+ - spv/ - will be used to output errors, produced during
+ the conversion from the SPIR-V to WGSL.
+ - wgsl/ - will be used to output errors, produced during
+ the conversion from the WGSL to `--fuzzing_target`.
+ - mutator/ - will be used to output errors, produced by
+ the mutators.
+ By default invalid files are not printed out.
+
+ -tint_fuzzing_target
+ The type of backend to target during fuzzing. This must
+ be one or a combination of `wgsl`, `spv`, `msl` or `hlsl`
+ (without `) separated by commas. By default it's
+ `wgsl,spv,msl,hlsl`.
+
+ -tint_help
+ Show this message. Note that there is also a -help=1
+ parameter that will display libfuzzer's help message.
+
+ -tint_mutator_cache_size=
+ The maximum size of the cache that stores
+ mutation sessions. This must fit in uint32_t.
+ By default it's 20.
+
+ -tint_mutator_type=
+ Determines types of the mutators to run. This must be one or
+ a combination of `fuzz`, `opt`, `reduce` (without `) separated by
+ comma. If a combination is specified, each element in the
+ combination will have an equal chance of mutating a SPIR-V
+ binary during a mutation session (i.e. if no mutator exists
+ for that binary in the mutator cache). By default, the
+ parameter's value is `fuzz,opt,reduce`.
+)";
+
+const char* const kMutatorDebuggerHelpMessage = R"(
+This tool is used to debug *mutators*. It uses CLI arguments similar to the
+ones used by the fuzzer. To debug some mutator you just need to specify the
+mutator type, the seed and the path to the SPIR-V binary that triggered the
+error. This tool will run the mutator on the binary until the error is
+produced or the mutator returns `kLimitReached`.
+
+Note that this is different from debugging the fuzzer by specifying input
+files to test. The difference is that the latter will not execute any
+mutator (it will only run the LLVMFuzzerTestOneInput function) whereas this
+tool is useful when one of the SPIRV-Tools mutators crashes or produces an
+invalid binary in LLVMFuzzerCustomMutator.
+
+Debugger parameters:
+
+ --help
+ Show this message.
+
+ --mutator_type=
+ Determines the type of the mutator to debug. This must be
+ one of `fuzz`, `reduce` or `opt` (without `). This parameter
+ is REQUIRED.
+
+ --original_binary=
+ The path to the SPIR-V binary that the faulty mutator was
+ initialized with. This will be dumped on errors by the fuzzer
+ if `--error_dir` is specified. This parameter is REQUIRED.
+
+ --seed=
+ The seed for the random number generator that was used to
+ initialize the mutator. This value is usually printed to
+ the console when the mutator produces an invalid binary.
+ It is also dumped into the log file if `--error_dir` is
+ specified. This must fit in uint32_t. This parameter is
+ REQUIRED.

+/// A structured control flow construct, consisting of a set of basic blocks.
+/// A construct is a span of blocks in the computed block order,
+/// and will appear contiguously in the WGSL source.
+///
+/// SPIR-V (2.11 Structured Control Flow) defines:
+/// - loop construct
+/// - continue construct
+/// - selection construct
+/// We also define a "function construct" consisting of all the basic blocks in
+/// the function.
+///
+/// The first block in a construct (by computed block order) is called a
+/// "header". For the constructs defined by SPIR-V, the header block is the
+/// basic block containing the merge instruction. The header for the function
+/// construct is the entry block of the function.
+///
+/// Given two constructs A and B, we say "A encloses B" if B is a subset of A,
+/// i.e. if every basic block in B is also in A. Note that a construct encloses
+/// itself.
+///
+/// In a valid SPIR-V module, constructs will nest, meaning given
+/// constructs A and B, either A encloses B, or B encloses A, or
+/// or they are disjoint (have no basic blocks in commont).
+///
+/// A loop in a high level language translates into either:
+//
+/// - a single-block loop, where the loop header branches back to itself.
+/// In this case this single-block loop consists only of the *continue
+/// construct*. There is no "loop construct" for this case.
+//
+/// - a multi-block loop, where the loop back-edge is different from the loop
+/// header.
+/// This case has both a non-empty loop construct containing at least the
+/// loop header, and a non-empty continue construct, containing at least the
+/// back-edge block.
+///
+/// We care about two kinds of selection constructs:
+///
+/// - if-selection: where the header block ends in OpBranchConditional
+///
+/// - switch-selection: where the header block ends in OpSwitch
+///

+//
+// Suppose H is a header block (i.e. has an OpSelectionMerge or OpLoopMerge).
+// Then:
+// - Let M(H) be the merge block named by the merge instruction in H.
+// - If H is a loop header, i.e. has an OpLoopMerge instruction, then let
+// CT(H) be the continue target block named by the OpLoopMerge
+// instruction.
+// - If H is a selection construct whose header ends in
+// OpBranchConditional with true target %then and false target %else,
+// then TT(H) = %then and FT(H) = %else
+//
+// Determining output block order:
+// The "structured post-order traversal" of the CFG is a post-order traversal
+// of the basic blocks in the CFG, where:
+// We visit the entry node of the function first.
+// When visiting a header block:
+// We next visit its merge block
+// Then if it's a loop header, we next visit the continue target,
+// Then we visit the block's successors (whether it's a header or not)
+// If the block ends in an OpBranchConditional, we visit the false target
+// before the true target.
+//
+// The "reverse structured post-order traversal" of the CFG is the reverse
+// of the structured post-order traversal.
+// This is the order of basic blocks as they should be emitted to the WGSL
+// function. It is the order computed by ComputeBlockOrder, and stored in
+// the |FunctionEmiter::block_order_|.
+// Blocks not in this ordering are ignored by the rest of the algorithm.
+//
+// Note:
+// - A block D in the function might not appear in this order because
+// no block in the order branches to D.
+// - An unreachable block D might still be in the order because some header
+// block in the order names D as its continue target, or merge block,
+// or D is reachable from one of those otherwise-unreachable continue
+// targets or merge blocks.
+//
+// Terms:
+// Let Pos(B) be the index position of a block B in the computed block order.
+//
+// CFG intervals and valid nesting:
+//
+// A correctly structured CFG satisfies nesting rules that we can check by
+// comparing positions of related blocks.
+//
+// If header block H is in the block order, then the following holds:
+//
+// Pos(H) < Pos(M(H))
+//
+// If CT(H) exists, then:
+//
+// Pos(H) <= Pos(CT(H))
+// Pos(CT(H)) < Pos(M)
+//
+// This gives us the fundamental ordering of blocks in relation to a
+// structured construct:
+// The blocks before H in the block order, are not in the construct
+// The blocks at M(H) or later in the block order, are not in the construct
+// The blocks in a selection headed at H are in positions [ Pos(H),
+// Pos(M(H)) ) The blocks in a loop construct headed at H are in positions
+// [ Pos(H), Pos(CT(H)) ) The blocks in the continue construct for loop
+// headed at H are in
+// positions [ Pos(CT(H)), Pos(M(H)) )
+//
+// Schematically, for a selection construct headed by H, the blocks are in
+// order from left to right:
+//
+// ...a-b-c H d-e-f M(H) n-o-p...
+//
+// where ...a-b-c: blocks before the selection construct
+// where H and d-e-f: blocks in the selection construct
+// where M(H) and n-o-p...: blocks after the selection construct
+//
+// Schematically, for a loop construct headed by H that is its own
+// continue construct, the blocks in order from left to right:
+//
+// ...a-b-c H=CT(H) d-e-f M(H) n-o-p...
+//
+// where ...a-b-c: blocks before the loop
+// where H is the continue construct; CT(H)=H, and the loop construct
+// is *empty*
+// where d-e-f... are other blocks in the continue construct
+// where M(H) and n-o-p...: blocks after the continue construct
+//
+// Schematically, for a multi-block loop construct headed by H, there are

+/// Notes on terminology:
+///
+/// A WGSL "handle" is an opaque object used for accessing a resource via
+/// special builtins. In SPIR-V, a handle is stored a variable in the
+/// UniformConstant storage class. The handles supported by SPIR-V are:
+/// - images, both sampled texture and storage image
+/// - samplers
+/// - combined image+sampler
+/// - acceleration structures for raytracing.
+///
+/// WGSL only supports samplers and images, but calls images "textures".
+/// When emitting errors, we aim to use terminology most likely to be
+/// familiar to Vulkan SPIR-V developers. We will tend to use "image"
+/// and "sampler" instead of "handle".

+/// related to the type of the variable in the shader. For example,
+/// `VertexFormat::kVec2F16` tells us that the buffer will contain `f16`
+/// elements, to be read as vec2. In the shader, a user would make a `vec2<f32>`
+/// to be able to use them. The conversion between `f16` and `f32` will need to
+/// be handled by us (using unpack functions).
+///
+/// To be clear, there won't be types such as `f16` or `u8` anywhere in WGSL
+/// code, but these are types that the data may arrive as. We need to convert
+/// these smaller types into the base types such as `f32` and `u32` for the

-/// The transform config determines whether to use global variables, structures,
-/// or parameters for the shader inputs and outputs, and optionally adds
-/// additional builtins to the shader interface.

-/// return 0.0;
-/// }
-/// var col : f32 = (coord.x * locations.loc1);

-/// to be able to use them. The conversion between `f16` and `f32` will need to
-/// be handled by us (using unpack functions).
-///
-/// To be clear, there won't be types such as `f16` or `u8` anywhere in WGSL
