* Move state var to private class member.Jim Grosbach2011-09-141-1/+1
| | | | llvm-svn: 139697
* First step in supporting #line directives in assembler. This step parses theKevin Enderby2011-09-131-1/+22
| | | | | | | | | #line directives with the needed support in the lexer. Next will be to build a simple file/line# table mapping source SMLoc's for later use by diagnostics. And the last step will be to get the diagnostics to use the mapping for file and line numbers. llvm-svn: 139669
* allow \r's in .s files.Chris Lattner2011-08-041-1/+1
| | | | llvm-svn: 136908
* Basic support for macros with explicit arguments.Rafael Espindola2011-06-051-0/+1

| | | | | | test for invalid hexadecimals. llvm-svn: 129326
* Lex, and then fail on invalid constants.Eric Christopher2011-04-111-1/+1
| | | | | | | | Testcase forthcoming. rdar://8490596 llvm-svn: 129309
* Clean up assembly statement separator support.Jim Grosbach2011-03-241-4/+14
| | | | | | | | The MC asm lexer wasn't honoring a non-default (anything but ';') statement separator. Fix that, and generalize a bit to support multi-character statement separators. llvm-svn: 128227
* More whitespace cleanup...Jim Grosbach2011-02-111-40/+40
| | | | llvm-svn: 125388
* Generalize a previous change, fixing PR8855 - an valid large immediateChris Lattner2010-12-251-6/+6
| | | | | | rejected by the mc assembler. llvm-svn: 122557
* Add missing standard headers. Patch by Joerg Sonnenberger!Nick Lewycky2010-12-191-0/+1
| | | | llvm-svn: 122193
* Add support for lexing single quotes like 'c'.Roman Divacky2010-12-181-0/+37
| | | | | | This fixed 8615. llvm-svn: 122150
* MC/AsmLexer: Fix bug in source location for Slash token.Daniel Dunbar2010-10-251-1/+1
| | | | llvm-svn: 117298
* MC/AsmParser: Handle exponents in floating point literals.Daniel Dunbar2010-09-271-9/+30
| | | | llvm-svn: 114861
* MC/AsmParser: Handle a missed case of floating literals in the lexer.Daniel Dunbar2010-09-241-1/+1
| | | | llvm-svn: 114733
* MC/Lexer: Add 'Real' token type for floating point literals.Daniel Dunbar2010-09-241-5/+24
| | | | llvm-svn: 114718
* fix rdar://7997827 - Accept and ignore LL and ULL suffixes on integer literals.Chris Lattner2010-08-241-2/+26
| | | | | | Also fix 0b010 syntax to actually work while we're at it :-) llvm-svn: 111876
* MC: Move getLoc() to MCAsmLexer().Daniel Dunbar2010-07-121-5/+0

* Convert some tab stops into spaces.Duncan Sands2010-07-121-1/+1
| | | | llvm-svn: 108130
* Add support for parsing the ELF .type assembler directive.Matt Fleming2010-05-211-0/+1

* Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and notKevin Enderby2010-05-181-1/+1
| | | | | | | CurPtr[0] == '\n' when testing the character after a "0b" when looking to see if it part of a something like "jmp 0b". llvm-svn: 104039
* Fixed the problem with a branch to "0b" that was not parsed by llvm-mcKevin Enderby2010-05-181-1/+0
| | | | | | | correctly. The Lexer was incorrectly eating the newline casusing it to branch to address 0. Updated the test case to use a "0:" label and a branch to "0b". llvm-svn: 104038
* Added support in MC for Directional Local Labels.Kevin Enderby2010-05-171-5/+7
| | | | llvm-svn: 103989
