From b40a90597b0b03eb04a14a494a43dcc7f58ae5f8 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Fri, 3 Dec 2010 01:55:30 +0000 Subject: [PATCH] Ignore decode table conflicts in the tMOVgpr2tgpr, tMOVgpr2gpr, and tMOVtgpr2gpr instructions. They are handled as special moves, but encoded as a normal move. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120779 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/TableGen/ARMDecoderEmitter.cpp | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/utils/TableGen/ARMDecoderEmitter.cpp b/utils/TableGen/ARMDecoderEmitter.cpp index 64e25c9ad8c..22b2c037368 100644 --- a/utils/TableGen/ARMDecoderEmitter.cpp +++ b/utils/TableGen/ARMDecoderEmitter.cpp @@ -1731,6 +1731,13 @@ ARMDEBackend::populateInstruction(const CodeGenInstruction &CGI, Name == "tSpill" || Name == "tLDRcp" || Name == "tRestore" || Name == "t2LEApcrelJT" || Name == "t2MOVCCi16") return false; + + // tMOVgpr2tgpr, tMOVgpr2gpr, and tMOVtgpr2gpr are used by the code + // generator for special kinds of moves, but are encoded the same.
