From 4dd82f6aaa483ef11bd74795c81cfc30b52821af Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Thu, 19 Feb 2009 09:16:38 +0000 Subject: [PATCH] Print out a new label only if the debug location *tuple* is different. The debug locations may change, but the tuples may be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65039 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/DebugLoc.h | 7 +++++++ utils/TableGen/AsmWriterEmitter.cpp | 15 +++++++++------ 2 files changed, 16 insertions(+), 6 deletions(-) diff --git a/include/llvm/CodeGen/DebugLoc.h b/include/llvm/CodeGen/DebugLoc.h index 505292846dd..d5ad9dcafd9 100644 --- a/include/llvm/CodeGen/DebugLoc.h +++ b/include/llvm/CodeGen/DebugLoc.h @@ -27,6 +27,13 @@ namespace llvm { DebugLocTuple(unsigned s, unsigned l, unsigned c) : Src(s), Line(l), Col(c) {}; + + bool operator==(const DebugLocTuple &DLT) const { + return Src == DLT.Src && Line == DLT.Line && Col == DLT.Col; + } + bool operator!=(const DebugLocTuple &DLT) const { + return !(*this == DLT); + } }; /// DebugLoc - Debug location id.
