Returns whether two operands are registers and are equal.
This is used by the tied-operands checks in the AsmMatcher. This method can be overridden to allow e.g. a sub- or super-register as the tied operand.

MatchAndEmitInstruction - Recognize a series of operands of a parsed instruction as an actual MCInst and emit it to the specified MCStreamer.
This returns false on success and returns true on failure to match.
On failure, the target parser is responsible for emitting a diagnostic explaining the match failure.
Allows targets to let registers opt out of clobber lists.

ParseDirective - Parse a target specific assembler directive This method is deprecated, use 'parseDirective' instead.
The parser is positioned following the directive name. The target specific directive parser should parse the entire directive doing or recording any target specific work, or return true and do nothing if the directive is not target specific. If the directive is specific for the target, the entire line is parsed up to and including the end-of-statement token and false is returned.
DirectiveID | - the identifier token of the directive. |

Parses a target-specific assembler directive.
The parser is positioned following the directive name. The target-specific directive parser should parse the entire directive doing or recording any target-specific work, or emit an error. On success, the entire line should be parsed up to and including the end-of-statement token. On failure, the parser is not required to read to the end of the line. If the directive is not target-specific, no tokens should be consumed and NoMatch is returned.

ParseInstruction - Parse one assembly instruction.
The parser is positioned following the instruction name. The target specific instruction parser should parse the entire instruction and construct the appropriate MCInst, or emit an error. On success, the entire line should be parsed up to and including the end-of-statement token. On failure, the parser is not required to read to the end of the line.
Name | - The instruction name. |
NameLoc | - The source location of the name. |
Operands | [out] - The list of parsed operands, this returns ownership of them to the caller. |

tryParseRegister - parse one register if possible
Check whether a register specification can be parsed at the current location, without failing the entire parse if it can't. Must not consume tokens if the parse fails.
|
inlinevirtual |
Allow a target to add special case operand matching for things that tblgen doesn't/can't handle effectively.
For example, literal immediates on ARM. TableGen expects a token operand, but the parser will recognize them as immediates.
