This PR (https://github.com/microsoft/DirectXShaderCompiler/pull/6598) pulls the upstream global reassociation algorithm change in DXC and can reduce redundant calculations obviously. However, from the testing result of a large offline suite of shaders, some shaders got worse compilation results and couldn't benefit from this upstream change. This PR adds a flag for the upstream global reassociation change. It would be easier to roll back if a shader get worse compilation result due to this upstream change. This is part 2 of the fix for #6593. |
