[LLVMdev] SimplifyLibCalls doesn't check TLI for LibFunc availability
Hi,
It looks like SimplifyLibCalls has a tendency to emit calls to libm functions without checking with TLI whether these calls are available.
For example, PowOpt has this code:
struct PowOpt : public UnsafeFPLibCallOptimization {
PowOpt(bool UnsafeFPShrink) : UnsafeFPLibCallOptimization(UnsafeFPShrink) {}
virtual Value *callOptimizer(Function *Callee, CallInst *CI, IRBuilder<> &B) {
Value *Ret = NULL;
if (UnsafeFPShrink && Callee->getName() == "pow" &&
