From af33b7b4a775073585f2037bf4cb56f1cd87d13c Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Wed, 4 Aug 2010 23:36:02 +0000 Subject: The lower invoke pass needs to have unreachable code elimination run after it because it could create such things. This fixes a MingW buildbot test failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110279 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/2010-08-04-MingWCrash.ll | 39 +++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 test/CodeGen/X86/2010-08-04-MingWCrash.ll (limited to 'test/CodeGen/X86/2010-08-04-MingWCrash.ll') diff --git a/test/CodeGen/X86/2010-08-04-MingWCrash.ll b/test/CodeGen/X86/2010-08-04-MingWCrash.ll new file mode 100644 index 0000000000..98a0887c0e --- /dev/null +++ b/test/CodeGen/X86/2010-08-04-MingWCrash.ll @@ -0,0 +1,39 @@ +; RUN: llc < %s -mtriple=i386-pc-mingw32 + +define void @func() nounwind { +invoke.cont: + %call = tail call i8* @malloc() + %a = invoke i32 @bar() + to label %bb1 unwind label %lpad + +bb1: + ret void + +lpad: + %exn = tail call i8* @llvm.eh.exception() nounwind + %eh.selector = tail call i32 (i8*, i8*, ...)* @llvm.eh.selector(i8* %exn, i8* bitcast (i32 (...)* @__gxx_personality_v0 to i8*), i32 1, i8* null) nounwind + %ehspec.fails = icmp slt i32 %eh.selector, 0 + br i1 %ehspec.fails, label %ehspec.unexpected, label %cleanup + +cleanup: + tail call void @_Unwind_Resume_or_Rethrow(i8* %exn) noreturn nounwind + unreachable + +ehspec.unexpected: + tail call void @__cxa_call_unexpected(i8* %exn) noreturn nounwind + unreachable +} + +declare noalias i8* @malloc() + +declare i8* @llvm.eh.exception() nounwind readonly + +declare i32 @__gxx_personality_v0(...) + +declare i32 @llvm.eh.selector(i8*, i8*, ...) nounwind + +declare void @_Unwind_Resume_or_Rethrow(i8*) + +declare void @__cxa_call_unexpected(i8*) + +declare i32 @bar() -- cgit v1.2.3
