This adds another volatile qualifier to a float variable declaration = in the weightCalcHelper() function, which otherwise produces slightly different float results on amd64 and i386 hosts. In turn, this can le= ad to different (but equivalent) register choices, and thus non-identical assembly code. See https://github.com/llvm/llvm-project/issues/99396 for more detail= s. Note this is a temporary fix, meant to merge in time for 13.4. As soon as upstream has a permanent solution we will import that.
