From ece2c04d532d46405c085769d03173b392813eb3 Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Sun, 16 Dec 2007 15:51:49 +0000 Subject: Make instcombine promote inline asm calls to 'nounwind' calls. Remove special casing of inline asm from the inliner. There is a potential problem: the verifier rejects invokes of inline asm (not sure why). If an asm call is not marked "nounwind" in some .ll, and instcombine is not run, but the inliner is run, then an illegal module will be created. This is bad but I'm not sure what the best approach is. I'm tempted to remove the check in the verifier... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45073 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/InlineFunction.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'lib/Transforms/Utils/InlineFunction.cpp') diff --git a/lib/Transforms/Utils/InlineFunction.cpp b/lib/Transforms/Utils/InlineFunction.cpp index e9f6b28e98..3d31f71300 100644 --- a/lib/Transforms/Utils/InlineFunction.cpp +++ b/lib/Transforms/Utils/InlineFunction.cpp @@ -69,9 +69,8 @@ static void HandleInlinedInvoke(InvokeInst *II, BasicBlock *FirstNewBlock, if (!isa(I)) continue; CallInst *CI = cast(I); - // If this call cannot unwind or is an inline asm, don't - // convert it to an invoke. - if (CI->isNoUnwind() || isa(CI->getCalledValue())) + // If this call cannot unwind, don't convert it to an invoke. + if (CI->isNoUnwind()) continue; // Convert this function call into an invoke instruction. -- cgit v1.2.3
