From 369de261e7cb2ec17b135d827af639300943562e Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Wed, 17 Jun 2009 00:48:26 +0000 Subject: [PATCH] Do not use first actual instruction's location for prologue. The debug wants to skip prologue while setting a breakpoint for the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73592 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86RegisterInfo.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/lib/Target/X86/X86RegisterInfo.cpp b/lib/Target/X86/X86RegisterInfo.cpp index b461b8a7a9c..a2f319f9a7a 100644 --- a/lib/Target/X86/X86RegisterInfo.cpp +++ b/lib/Target/X86/X86RegisterInfo.cpp @@ -729,8 +729,7 @@ void X86RegisterInfo::emitPrologue(MachineFunction &MF) const { bool needsFrameMoves = (MMI && MMI->hasDebugInfo()) || !Fn->doesNotThrow() || UnwindTablesMandatory; - DebugLoc DL = (MBBI != MBB.end() ?
