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,...
Although DXC applied the upstream change, Reassociate: add global reassociation algorithm (https://github.com/llvm/llvm-project/commit/b8a330c) in this PR (https://github.com/microsoft/DirectXShaderCompiler/pull/6598), it still might overlook some obvious common factors. One case has been observed is:...

**Description** DXC is missing common factor optimization in some cases. Here's an example code: ``` cbuffer TemporalAAData : register ( b10 ) { float2 viewportRelativeSize ; float4 outputDimensions ; }...
