From a9d6680cb1db34f6eedf7f5f1875da1dd47ba8ca Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Mon, 31 May 2010 06:16:35 +0000 Subject: The memcpy intrinsic only takes i8* for %src and %dst, so cast them to that first. Fixes PR7265. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105206 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../SimplifyLibCalls/2010-05-30-memcpy-Struct.ll | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 test/Transforms/SimplifyLibCalls/2010-05-30-memcpy-Struct.ll (limited to 'test/Transforms/SimplifyLibCalls') diff --git a/test/Transforms/SimplifyLibCalls/2010-05-30-memcpy-Struct.ll b/test/Transforms/SimplifyLibCalls/2010-05-30-memcpy-Struct.ll new file mode 100644 index 0000000..f67bae7 --- /dev/null +++ b/test/Transforms/SimplifyLibCalls/2010-05-30-memcpy-Struct.ll @@ -0,0 +1,20 @@ +; RUN: opt -simplify-libcalls %s -S -o - | FileCheck %s +; PR7265 + +target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64" +target triple = "x86_64-unknown-linux-gnu" + +%union.anon = type { i32, [4 x i8] } + +@.str = private constant [3 x i8] c"%s\00" ; <[3 x i8]*> [#uses=2] + +define void @CopyEventArg(%union.anon* %ev) nounwind { +entry: + %call = call i32 (i8*, i8*, ...)* @sprintf(i8* undef, i8* getelementptr inbounds ([3 x i8]* @.str, i64 0, i64 0), %union.anon* %ev) nounwind ; [#uses=0] +; CHECK: bitcast %union.anon* %ev to i8* +; CHECK: call void @llvm.memcpy.p0i8.p0i8.i64 + ret void +} + +declare i32 @sprintf(i8*, i8*, ...) + -- cgit v1.1
