FENV_ACCESS and floating point LibFunc calls
Sounds like the select lowering issue is definitely separate from the FENV
work.
Is there a bug report with a C or IR example? You want to generate compare
and branch instead of a cmov for something like this?
int foo(float x) {
if (x < 42.0f)
return x;
return 12;
}
define i32 @foo(float %x) {
%cmp = fcmp olt float %x, 4.200000e+01
%conv = fptosi float %x to i32
%ret = select
