Demo illustrating the problem
Hello,
I seem to get an infinite loop with simple function calling a f64 intrinsic.
I reproduced the problem with lli/llc with the following snippet:
declare double @llvm.floor.f64(double) #0
define double @floor(double) {
entry:
%tmp = call double @llvm.floor.f64(double %0)
ret double %tmp
}
define void @main() {
call double @floor(double 0.0)
ret void
}
attributes #0 = { nounwind readnone speculatable }
Changing the name of @floor, or switching to f32 seem to resolve the problem.
Using revision 315749.</pre>
