From 5c0d6ed325417baa5d119af9c2b6790231d8565f Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Fri, 19 Oct 2007 10:41:11 +0000 Subject: Add support for byval function whose argument is not 32 bit aligned. To do this it is necessary to add a "always inline" argument to the memcpy node. For completeness I have also added this node to memmove and memset. I have also added getMem* functions, because the extra argument makes it cumbersome to use getNode and because I get confused by it :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43172 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/byval4.ll | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 test/CodeGen/X86/byval4.ll (limited to 'test/CodeGen/X86/byval4.ll') diff --git a/test/CodeGen/X86/byval4.ll b/test/CodeGen/X86/byval4.ll new file mode 100644 index 0000000..9ce635b --- /dev/null +++ b/test/CodeGen/X86/byval4.ll @@ -0,0 +1,28 @@ +; RUN: llvm-as < %s | llc -march=x86-64 | grep rep.movsl | count 2 +; RUN: llvm-as < %s | llc -march=x86 | grep rep.movsw | count 2 + +%struct.s = type { i16, i16, i16, i16, i16, i16 } + + +define void @g(i16 signext %a1, i16 signext %a2, i16 signext %a3, + i16 signext %a4, i16 signext %a5, i16 signext %a6) { +entry: + %a = alloca %struct.s, align 16 + %tmp = getelementptr %struct.s* %a, i32 0, i32 0 + store i16 %a1, i16* %tmp, align 16 + %tmp2 = getelementptr %struct.s* %a, i32 0, i32 1 + store i16 %a2, i16* %tmp2, align 16 + %tmp4 = getelementptr %struct.s* %a, i32 0, i32 2 + store i16 %a3, i16* %tmp4, align 16 + %tmp6 = getelementptr %struct.s* %a, i32 0, i32 3 + store i16 %a4, i16* %tmp6, align 16 + %tmp8 = getelementptr %struct.s* %a, i32 0, i32 4 + store i16 %a5, i16* %tmp8, align 16 + %tmp10 = getelementptr %struct.s* %a, i32 0, i32 5 + store i16 %a6, i16* %tmp10, align 16 + call void @f( %struct.s* %a byval ) + call void @f( %struct.s* %a byval ) + ret void +} + +declare void @f(%struct.s* byval) -- cgit v1.1
