From 281ae5abf57a4d318d308c0dd1326ff65d540b78 Mon Sep 17 00:00:00 2001 From: Michael Liao Date: Wed, 17 Oct 2012 02:22:27 +0000 Subject: Fix setjmp on models with non-Small code model nor non-Static relocation model - MBB address is only valid as an immediate value in Small & Static code/relocation models. On other models, LEA is needed to load IP address of the restore MBB. - A minor fix of MBB in MC lowering is added as well to enable target relocation flag being propagated into MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166084 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/sjlj.ll | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) (limited to 'test') diff --git a/test/CodeGen/X86/sjlj.ll b/test/CodeGen/X86/sjlj.ll index d594e98299..681db00943 100644 --- a/test/CodeGen/X86/sjlj.ll +++ b/test/CodeGen/X86/sjlj.ll @@ -1,5 +1,7 @@ ; RUN: llc < %s -mtriple=i386-pc-linux -mcpu=corei7 -relocation-model=static | FileCheck --check-prefix=X86 %s -; RUN: llc < %s -mtriple=x86_64-pc-linux -mcpu=corei7 | FileCheck --check-prefix=X64 %s +; RUN: llc < %s -mtriple=i386-pc-linux -mcpu=corei7 -relocation-model=pic | FileCheck --check-prefix=PIC86 %s +; RUN: llc < %s -mtriple=x86_64-pc-linux -mcpu=corei7 -relocation-model=static | FileCheck --check-prefix=X64 %s +; RUN: llc < %s -mtriple=x86_64-pc-linux -mcpu=corei7 -relocation-model=pic | FileCheck --check-prefix=PIC64 %s @buf = internal global [5 x i8*] zeroinitializer @@ -20,14 +22,26 @@ define i32 @sj0() nounwind { ret i32 %r ; X86: sj0 ; x86: movl %ebp, buf -; x86: movl ${{.*LBB.*}}, buf+4 ; X86: movl %esp, buf+8 +; x86: movl ${{.*LBB.*}}, buf+4 ; X86: ret +; PIC86: sj0 +; PIC86: movl %ebp, buf@GOTOFF(%[[GOT:.*]]) +; PIC86: movl %esp, buf@GOTOFF+8(%[[GOT]]) +; PIC86: leal {{.*LBB.*}}@GOTOFF(%[[GOT]]), %[[LREG:.*]] +; PIC86: movl %[[LREG]], buf@GOTOFF+4 +; PIC86: ret ; X64: sj0 ; x64: movq %rbp, buf(%rip) ; x64: movq ${{.*LBB.*}}, buf+8(%rip) ; X64: movq %rsp, buf+16(%rip) ; X64: ret +; PIC64: sj0 +; PIC64: movq %rbp, buf(%rip) +; PIC64: movq %rsp, buf+16(%rip) +; PIC64: leaq {{.*LBB.*}}(%rip), %[[LREG:.*]] +; PIC64: movq %[[LREG]], buf+8(%rip) +; PIC64: ret } define void @lj0() nounwind { -- cgit v1.2.3
