Igor Shaposhnik 8df5421e2e [glsl-out] Add stage postfix to generated global name (#1616) 2021-12-23 22:19:07 -05:00
Jay Oster 924ab17b62 Fixes for fma function (#1580) 
* [hlsl-out] Write `mad` intrinsic for `fma` function

- This should be enough because we only support f32 for now.
- Adds a new test for WGSL functions, in the spirit of operators.wgsl.
- Closes #1579

* Add FMA feature to glsl backend

- I think this is right. Just iterate all known expressions in all
  functions and entry points to locate any `fma` function call.
  Should not need to walk the statement DAG.

* Transform GLSL fma function into an airthmetic expression when necessary

* Add tests for GLSL fma function tranformation

* Remove the hazard comment from the webgl test input

* Add helper method for fma function support checks

* Address review comment

João Capucho 9c75f3cdce glsl-in: Flatten entry point arguments 
The IR doesn't allow having structs has bindings for entry point
input/output, so the glsl frontend must flatten them.

Glsl defines that the locations are sequential from the block base location.
