From b0a258be2f154e83ef6ffe5f2437aa648a1279ca Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Sun, 11 Jul 2010 05:17:06 +0000 Subject: [PATCH] Remove copyRegToReg from TargetInstrInfo so it is not longer accesible. Use a COPY instruction instead for register copies, or TII::copyPhysReg() after COPY instructions are lowered. Targets should implement copyPhysReg instead of copyRegToReg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108075 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/TargetInstrInfo.h | 25 ++++++++++++------------- 1 file changed, 12 insertions(+), 13 deletions(-) diff --git a/include/llvm/Target/TargetInstrInfo.h b/include/llvm/Target/TargetInstrInfo.h index b505d16b576..6a4573b4fde 100644 --- a/include/llvm/Target/TargetInstrInfo.h +++ b/include/llvm/Target/TargetInstrInfo.h @@ -353,19 +353,6 @@ public: return false; } - /// copyRegToReg - Emit instructions to copy between a pair of registers.
