From 7540565863c11ae3a65fe1a8159cedc0caf55c07 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sun, 17 Aug 2003 23:20:40 +0000 Subject: [PATCH] Fix ABI issue: Longs really do need to be only 4 byte aligned on X86. This bug caused miscompilation of programs using 'struct stat', but only if compiled with support for 64-bit filesystems. This could in theory effect other things, but only if the LLVM code shared data structures with native code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7928 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86TargetMachine.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/Target/X86/X86TargetMachine.cpp b/lib/Target/X86/X86TargetMachine.cpp index e3cc88078cf..6a88390963c 100644 --- a/lib/Target/X86/X86TargetMachine.cpp +++ b/lib/Target/X86/X86TargetMachine.cpp @@ -39,7 +39,8 @@ X86TargetMachine::X86TargetMachine(unsigned Config) (Config & TM::EndianMask) == TM::LittleEndian, (Config & TM::PtrSizeMask) == TM::PtrSize64 ? 8 : 4, (Config & TM::PtrSizeMask) == TM::PtrSize64 ? 8 : 4, - (Config & TM::PtrSizeMask) == TM::PtrSize64 ? 8 : 4), + (Config & TM::PtrSizeMask) == TM::PtrSize64 ? 8 : 4, + 4, (Config & TM::PtrSizeMask) == TM::PtrSize64 ? 8 : 4), FrameInfo(TargetFrameInfo::StackGrowsDown, 8/*16 for SSE*/, 4) { }
