guiand added a comment.
I've run across an issue when bootstrapping clang, that manifests itself in the
following code when compiled with optimizations:
#include <math.h>
float my_exp2(float a) {
return pow(2.0, a);
}
With this code, the call to `pow` is lifted to a `exp2`, and then the resulting
call causes `llvm::verifyFunction` to fail. The error is that attributes are
present past the end of the argument list.
I'm thinking that whatever code does the lifting here fails to remove the
attribute list corresponding to the `2.0` parameter here.
Could anyone point me to where I might need to make a change for that?
