示例1: CastToCStr
/// EmitFPutS - Emit a call to the puts function. Str is required to be a
/// pointer and File is a pointer to FILE.
Value *llvm::EmitFPutS(Value *Str, Value *File, IRBuilder<> &B,
const DataLayout *TD, const TargetLibraryInfo *TLI) {
if (!TLI->has(LibFunc::fputs))
return 0;
Module *M = B.GetInsertBlock()->getParent()->getParent();
AttributeSet AS[3];
AS[0] = AttributeSet::get(M->getContext(), 1, Attribute::NoCapture);
AS[1] = AttributeSet::get(M->getContext(), 2, Attribute::NoCapture);
AS[2] = AttributeSet::get(M->getContext(), AttributeSet::FunctionIndex,
Attribute::NoUnwind);
StringRef FPutsName = TLI->getName(LibFunc::fputs);
Constant *F;
if (File->getType()->isPointerTy())

/// an integer and File is a pointer to FILE.
