From 216f63702fabd57ac570feebc56005b2a5cb3216 Mon Sep 17 00:00:00 2001 From: Joerg Sonnenberger Date: Tue, 10 Jan 2012 22:43:53 +0000 Subject: Default stack alignment for 32bit x86 should be 4 Bytes, not 8 Bytes. Add a test that checks the stack alignment of a simple function for Darwin, Linux and NetBSD for 32bit and 64bit mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147888 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/stack-align2.ll | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 test/CodeGen/X86/stack-align2.ll (limited to 'test/CodeGen/X86/stack-align2.ll') diff --git a/test/CodeGen/X86/stack-align2.ll b/test/CodeGen/X86/stack-align2.ll new file mode 100644 index 0000000..5523c0e --- /dev/null +++ b/test/CodeGen/X86/stack-align2.ll @@ -0,0 +1,25 @@ +; RUN: llc < %s -mtriple=i386-linux | FileCheck %s -check-prefix=LINUX-I386 +; RUN: llc < %s -mtriple=i386-netbsd | FileCheck %s -check-prefix=NETBSD-I386 +; RUN: llc < %s -mtriple=i686-apple-darwin8 | FileCheck %s -check-prefix=DARWIN-I386 +; RUN: llc < %s -mtriple=x86_64-linux | FileCheck %s -check-prefix=LINUX-X86_64 +; RUN: llc < %s -mtriple=x86_64-netbsd | FileCheck %s -check-prefix=NETBSD-X86_64 +; RUN: llc < %s -mtriple=x86_64-apple-darwin8 | FileCheck %s -check-prefix=DARWIN-X86_64 + +define i32 @test() nounwind { +entry: + call void @test2() + ret i32 0 + +; LINUX-I386: subl $12, %esp +; DARWIN-I386: subl $12, %esp +; NETBSD-I386-NOT: subl {{.*}}, %esp + +; LINUX-X86_64: pushq %{{.*}} +; LINUX-X86_64-NOT: subq {{.*}}, %rsp +; DARWIN-X86_64: pushq %{{.*}} +; DARWIN-X86_64-NOT: subq {{.*}}, %rsp +; NETBSD-X86_64: pushq %{{.*}} +; NETBSD-X86_64-NOT: subq {{.*}}, %rsp +} + +declare void @test2() -- cgit v1.1
