* Allow vecN<i32> and vecN<u32> in `dot()`, first changes
* Added a test case
* Fix the test
* Changes to baking of expressions, incl args of integer dot product
* Implemented requested changes for glsl backend
* Added support for integer dot product on MSL backend
* Removed outdated code for hlsl and wgls writers
* Implement in spv backend
* Commit modified outputs from running the tests
* cargo fmt
* Applied requested changes for both MSL and GLSL back
* Changes to spv back
* Committed all test output changes
* Cargo fmt
* Added a comment w.r.t. VK_KHR_shader_integer_dot_product
* Implemented requested svp change
* Minor change to test case
This is because I wanted to highlight the fact that the correct
id is used in the last sum of the integer dot product expression
* Changed function signature
since it could not fail, changed it to simply return `void`
* Rewrite front/back doc summaries
- Use line comments instead of block comments
- Standardize language for each front/backend
- Add reference link for each format
- Minor punctuation changes
* Add documentation for keywords module
* Clarify contents of keywords module in summary
* Refer to modules by their type name
* Add basic summary for valid module
* Adjust EarlyDepthTest and ConservativeDepth docs
* Remove "in" from list
* Adjust wording
* Standardize format of docstrings
* Adjust module links to be consistent with other links
* Add summary for reserved keywords list
* Remove extraneous doc spaces with `cargo fmt`
* Correct spelling of whether and rewrite some lines
* Fill out GLSL backend docs
* Remove unnecessary link targets
* Fill out DOT backend docs
* Change module line comments to block comments
* Remove unnecessary spaces
* Fix mistake during rebasing
* WGSL storage address space should always correspond to MSL device address space.
See MSL spec section 4.2.
* Update baselines
* Add error for storage address space if MSL version < 2.
* Update default MSL version to 2.0.
Fixes#1642.
Since 1d textures cannot have mipmaps, MSL requires that the `level` argument to
texel accesses and dimension queries be a constexpr 0. For our purposes, just
omit the level argument altogether.
* [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
* Add FindLsb / FindMsb
* Fixes and tests for FindLsb/FindMsb
* Add findLsb / findMsb as WGSL builtins
* Fix tests
* Fix incompatible type issue with MSL output
* Requested changes
* Test fewer cases of findLsb/findMsb
