* Remove an overly-eager assertion when replacing tokens with anDouglas Gregor2009-11-121-2/+0
| | | | | | | | | | | annotation token, because some of the tokens we're annotating might not be in the set of cached tokens (we could have consumed them unconditionally). Also, move the tentative parsing from ParseTemplateTemplateArgument into the one caller that needs it, improving recovery. llvm-svn: 86904

* This change refactors some of the low-level lexer interfaces a bit.Chris Lattner2009-01-261-1/+1
| | | | | | | | | | | | | Token now has a class of kinds for "literals", which include numeric constants, strings, etc. These tokens can optionally have a pointer to the start of the token in the lexer buffer. This makes it faster to get spelling and do other gymnastics, because we don't have to go through source locations. This change is performance neutral, but will make other changes more feasible down the road. llvm-svn: 63028
* Remove Preprocessor::CacheTokens boolean data member. The same functionality ↵Argyrios Kyrtzidis2008-11-191-4/+1

efficient lookahead and backtracking. 1) New public methods added: -EnableBacktrackAtThisPos -DisableBacktrack -Backtrack -isBacktrackEnabled 2) LookAhead() implementation is replaced with a more efficient one. 3) LookNext() is removed. llvm-svn: 54611
