From 4869d346e3c50fd7182c275a21169722161d541c Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 6 Nov 2010 19:57:21 +0000 Subject: add (and document) the ability for alias results to have fixed physical registers. Start moving fp comparison aliases to the .td file (which default to using %st1 if nothing is specified). llvm-svn: 118352 --- llvm/utils/TableGen/CodeGenInstruction.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'llvm/utils/TableGen/CodeGenInstruction.h') diff --git a/llvm/utils/TableGen/CodeGenInstruction.h b/llvm/utils/TableGen/CodeGenInstruction.h index ac593dfb17d..9cd23e6fa82 100644 --- a/llvm/utils/TableGen/CodeGenInstruction.h +++ b/llvm/utils/TableGen/CodeGenInstruction.h @@ -275,18 +275,22 @@ namespace llvm { public: enum { K_Record, - K_Imm + K_Imm, + K_Reg } Kind; ResultOperand(StringRef N, Record *r) : Name(N), R(r), Kind(K_Record) {} ResultOperand(int64_t I) : Imm(I), Kind(K_Imm) {} + ResultOperand(Record *r) : R(r), Kind(K_Reg) {} bool isRecord() const { return Kind == K_Record; } bool isImm() const { return Kind == K_Imm; } + bool isReg() const { return Kind == K_Reg; } StringRef getName() const { assert(isRecord()); return Name; } Record *getRecord() const { assert(isRecord()); return R; } int64_t getImm() const { assert(isImm()); return Imm; } + Record *getRegister() const { assert(isReg()); return R; } }; /// ResultOperands - The decoded operands for the result instruction. -- cgit v1.2.3
