tint: optimize compile time for const_eval_*_test files The reason for slow compile times is because the very large variants of builder::Value<T>s combined with the many std::visits over these variants result in many combinatorial instantiations of the visit callbacks. To address this, I added a polymorphic base class ValueBase to Value<T>, and replaced most of the std::visit-based compile time code with runtime virtual calls. For the two heaviest users of std::visit over the large variants, compiles times dropped more than half (clang-10, debug): const_eval_binary_op_test.cc: 19.079s to 7.736s const_eval_unary_op_test.cc: 10.021s to 4.789s Bug: tint:1711 Change-Id: Iba05e6ae1004ef0814250e2a8ea50aa2b26b85f2 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/105782 Reviewed-by: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements 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:
