From 028dba376ae90c82b44d72ddb3ed97849484aab4 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Wed, 23 Jan 2013 17:52:29 +0000 Subject: Revert "InstCombine: Clean up weird code that talks about a modulus that's long gone." This causes crashes during the build of compiler-rt during selfhost. Add a testcase for coverage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173279 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/InstCombine/getelementptr.ll | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'test/Transforms/InstCombine/getelementptr.ll') diff --git a/test/Transforms/InstCombine/getelementptr.ll b/test/Transforms/InstCombine/getelementptr.ll index 1c120ecbe9..03e26eb67e 100644 --- a/test/Transforms/InstCombine/getelementptr.ll +++ b/test/Transforms/InstCombine/getelementptr.ll @@ -492,3 +492,19 @@ define void @three_gep_f(%three_gep_t2* %x) { declare void @three_gep_g(i32*) declare void @three_gep_h(%three_gep_t2*) + +%struct.ham = type { i32, %struct.zot*, %struct.zot*, %struct.zot* } +%struct.zot = type { i64, i8 } + +define void @test39(%struct.ham* %arg, i8 %arg1) nounwind { + %tmp = getelementptr inbounds %struct.ham* %arg, i64 0, i32 2 + %tmp2 = load %struct.zot** %tmp, align 8 + %tmp3 = bitcast %struct.zot* %tmp2 to i8* + %tmp4 = getelementptr inbounds i8* %tmp3, i64 -8 + store i8 %arg1, i8* %tmp4, align 8 + ret void + +; CHECK: @test39 +; CHECK: getelementptr inbounds %struct.ham* %arg, i64 0, i32 2 +; CHECK: getelementptr inbounds i8* %tmp3, i64 -8 +} -- cgit v1.2.3
