[LLVMdev] Fast-math flags in constant expressions
Hi,
I'm wondering why lib/AsmParser/LLParser handles fast-math flags in the
following IR:
...
%val = fmul nnan double 1.0, 1.0
...
but doesn't allow any flags if "fmul" is inside "phi":
...
%val = phi double [ fmul (double 1.0, double 1.0), %cond.true ],
[ fmul (double 1.0, double 1.0), %cond.false ]
...

[LLVMdev] Fast-math flags in constant expressions
...s that would be relevant if the expression can just be constant-folded away at full precision anyways.
