Zhaoming Jiang	0d3d3210d4	tint/writer/glsl: Support for F16 type, constructor, and convertor ... This patch make GLSL writer support emitting f16 types, f16 literals, f16 constructor and convertor. Unittests are also implemented, and end-to-end testcases are updated for GLSL extension requirement. The GLSL writer will require `GL_AMD_gpu_shader_half_float` extension if f16 WGSL extension is enabled, emit f16 literal as `1.23hf`, and map f16 types as follow: WGSL type -> GLSL type f16 -> float16_t vec2<f16> -> f16vec2 vec3<f16> -> f16vec3 vec4<f16> -> f16vec4 mat2x2<f16> -> f16mat2 mat2x3<f16> -> f16mat2x3 mat2x4<f16> -> f16mat2x4 mat3x2<f16> -> f16mat3x2 mat3x3<f16> -> f16mat3 mat3x4<f16> -> f16mat3x4 mat4x2<f16> -> f16mat4x2 mat4x3<f16> -> f16mat4x3 mat4x4<f16> -> f16mat4 Bug: tint:1473, tint:1502 Change-Id: I7e788f82be2873911961c891a644200c1cbb74db Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/95684 Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Zhaoming Jiang <zhaoming.jiang@intel.com> Reviewed-by: Ben Clayton <bclayton@google.com>	2022-07-11 03:02:28 +00:00
Ben Clayton	7f2b8cd8fc	tint: Refactor Extensions / Enables. ... * Extract ast::Enable::ExtensionKind to ast::Extension. * Move the parsing out of ast::Enable and next to ast/extension.h * Change the ast::Enable constructor to take the Extension, instead of a std::string. It's the WGSL parser's responsibility to parse, not the AST nodes. * Add ProgramBuilder::Enable() helper. * Keep ast::Module simple - keep track of the declared AST Enable nodes, don't do any deduplicating of the enabled extensions. * Add the de-duplicated ast::Extensions to the sem::Module. * Remove the kInternalExtensionForTesting enum value - we have kF16 now, which can be used instead for testing. * Rename kNoExtension to kNone.
