From bfb44ef9cb430ef35ee1192388a08dbb283d0632 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Fri, 8 Feb 2013 21:48:29 +0000 Subject: Revert "Add LLVMContext::emitWarning methods and use them. " This reverts r171041. This was a nice idea that didn't work out well. Clang warnings need to be associated with warning groups so that they can be selectively disabled, promoted to errors, etc. This simplistic patch didn't allow for that. Enhancing it to provide some way for the backend to specify a front-end warning type seems like overkill for the few uses of this, at least for now. llvm-svn: 174748 --- llvm/lib/CodeGen/IntrinsicLowering.cpp | 36 +++++++++++++--------------------- 1 file changed, 14 insertions(+), 22 deletions(-) (limited to 'llvm/lib/CodeGen/IntrinsicLowering.cpp') diff --git a/llvm/lib/CodeGen/IntrinsicLowering.cpp b/llvm/lib/CodeGen/IntrinsicLowering.cpp index 16e7968eb45..07f0ccf52f8 100644 --- a/llvm/lib/CodeGen/IntrinsicLowering.cpp +++ b/llvm/lib/CodeGen/IntrinsicLowering.cpp @@ -413,30 +413,22 @@ void IntrinsicLowering::LowerIntrinsicCall(CallInst *CI) { } case Intrinsic::stacksave: + case Intrinsic::stackrestore: { if (!Warned) - Context.emitWarning("this target does not support the " - "llvm.stacksave intrinsic"); - Warned = true; - CI->replaceAllUsesWith(Constant::getNullValue(CI->getType())); - break; - - case Intrinsic::stackrestore: - if (!Warned) - Context.emitWarning("this target does not support the " - "llvm.stackrestore intrinsic"); + errs() << "WARNING: this target does not support the llvm.stack" + << (Callee->getIntrinsicID() == Intrinsic::stacksave ? + "save" : "restore") << " intrinsic.\n"; Warned = true; + if (Callee->getIntrinsicID() == Intrinsic::stacksave) + CI->replaceAllUsesWith(Constant::getNullValue(CI->getType())); break; + } case Intrinsic::returnaddress: - Context.emitWarning("this target does not support the " - "llvm.returnaddress intrinsic"); - CI->replaceAllUsesWith(ConstantPointerNull::get( - cast(CI->getType()))); - break; - case Intrinsic::frameaddress: - Context.emitWarning("this target does not support the " - "llvm.frameaddress intrinsic"); + errs() << "WARNING: this target does not support the llvm." + << (Callee->getIntrinsicID() == Intrinsic::returnaddress ? + "return" : "frame") << "address intrinsic.\n"; CI->replaceAllUsesWith(ConstantPointerNull::get( cast(CI->getType()))); break; @@ -446,12 +438,12 @@ void IntrinsicLowering::LowerIntrinsicCall(CallInst *CI) { case Intrinsic::pcmarker: break; // Simply strip out pcmarker on unsupported architectures - case Intrinsic::readcyclecounter: - Context.emitWarning("this target does not support the " - "llvm.readcyclecounter intrinsic; " - "it is being lowered to a constant 0"); + case Intrinsic::readcyclecounter: { + errs() << "WARNING: this target does not support the llvm.readcyclecoun" + << "ter intrinsic.
