DAG: Pass flags to FoldConstantArithmetic (#93663)

arsenm · web-flow · commit 84b026690ded · 2024-06-06T16:44:07.000+02:00
There is simply way too much going on inside getNode. The complicated
constant folding of vector handling works by looking for build_vector
operands, and then tries to getNode the scalar element and then checks
if
constants were the result. As a side effect, this produces unused scalar
operation nodes (previously, without flags). If the vector operation
were later scalarized, it would find the flagless constant folding
temporary and lose the flag. I don't think this is a reasonable way for
constant folding to operate, but for now fix this by ensuring flags
on the original operation are preserved in the temporary.
    
This yields a clear code improvement for AMDGPU when f16 isn't legal.
The Wasm cases switch from using a libcall to compare and select. We are
evidently
missing the fcmp+select to fminimum/fmaximum handling, but this would be
further
improved when that's handled. AArch64 also avoids the libcall, but looks
worse and
has a different call for some reason.
