From dc54d317e7a381ef8e4aca80d54ad1466bb85dda Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Mon, 9 Feb 2009 07:14:22 +0000 Subject: Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty suprise to some callers, e.g. register coalescer. For now, add an parameter that tells AnalyzeBranch whether it's safe to modify the mbb. A better solution is out there, but I don't have time to deal with it right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64124 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/XCore/XCoreInstrInfo.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/Target/XCore/XCoreInstrInfo.h') diff --git a/lib/Target/XCore/XCoreInstrInfo.h b/lib/Target/XCore/XCoreInstrInfo.h index a2c1e67c70..965ad367a9 100644 --- a/lib/Target/XCore/XCoreInstrInfo.h +++ b/lib/Target/XCore/XCoreInstrInfo.h @@ -56,7 +56,8 @@ public: virtual bool AnalyzeBranch(MachineBasicBlock &MBB, MachineBasicBlock *&TBB, MachineBasicBlock *&FBB, - SmallVectorImpl &Cond) const; + SmallVectorImpl &Cond, + bool AllowModify) const; virtual unsigned InsertBranch(MachineBasicBlock &MBB, MachineBasicBlock *TBB, MachineBasicBlock *FBB, -- cgit v1.2.3
