2009-11-12Remove an overly-eager assertion when replacing tokens with anDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86904 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-26fix segfault (because of erasing after the vector boundaries) when the ↵Nuno Lopes
cached token position is at the end git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77159 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26This change refactors some of the low-level lexer interfaces a bit.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63028 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Remove Preprocessor::CacheTokens boolean data member. The same functionality ↵Argyrios Kyrtzidis
can be provided by using Preprocessor::isBacktrackEnabled(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59631 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-08Introduce annotation tokens, a special kind of token, created and used only ↵Argyrios Kyrtzidis
by the parser to replace a group of tokens with a single token encoding semantic information. Will be fully utilized later for C++ nested-name-specifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58911 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-10Allow the preprocessor to cache the lexed tokens, so that we can do ↵Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54611 91177308-0d34-0410-b5e6-96231b3b80d8
