From 25f5cbcd13acc06c3b7d1cd9904b95b70cb4a641 Mon Sep 17 00:00:00 2001 From: Chad Rosier Date: Tue, 2 Oct 2012 21:49:07 +0000 Subject: [ms-inline asm] Add basic support for wildcard MCParsedAsmOperands. This type of operand is specific to MS-style inline assembly and should not be generated when parsing normal assembly. The purpose of the wildcard operands are to allow the AsmParser to match multiple instructions (i.e., MCInsts) to a given ms-style asm statement. For the time being the matcher just returns the first match. This patch only implements wildcard matches for memory operands. Support for register wildcards will be added in the near future. llvm-svn: 165057 --- llvm/include/llvm/MC/MCParser/MCParsedAsmOperand.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'llvm/include') diff --git a/llvm/include/llvm/MC/MCParser/MCParsedAsmOperand.h b/llvm/include/llvm/MC/MCParser/MCParsedAsmOperand.h index 0ce32d617ef..06e9dc90652 100644 --- a/llvm/include/llvm/MC/MCParser/MCParsedAsmOperand.h +++ b/llvm/include/llvm/MC/MCParser/MCParsedAsmOperand.h @@ -34,6 +34,13 @@ public: /// isMem - Is this a memory operand? virtual bool isMem() const = 0; + /// isMSAsmWildcard - Is this a wildcard operand?
