2008-03-09Rename MacroExpander.cpp/h -> TokenLexer.cpp/hChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48072 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-09rename the MacroExpander class to TokenLexer. It handles bothChris Lattner
token streams and macro lexing, so a more generic name is useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48071 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-09rename MacroTokens -> Tokens. When this is a token stream, there is no macroChris Lattner
involved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48070 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Implement support for the extremely atrocious MS /##/ extension, Chris Lattner
which pastes together a comment. This is only enabled with -fms-extensions of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Fix a bug where we would incorrectly emit a "cannot paste" error Chris Lattner
message when handling the GNU ", ## __VA_ARGS__" extension. While I'm at it, flag uses of this as extensions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46503 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09Switch lexer/pp over to new Token::is/isNot apiChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42799 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07improve layering:Chris Lattner
Now instead of IdentifierInfo knowing anything about MacroInfo, only the preprocessor knows. This makes MacroInfo truly private to the Lex library (and its direct clients) instead of being accessed in the Basic library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42727 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-22Fix a really subtle bug in the macro expander caching code, whereChris Lattner
redefinition of a macro could cause invalid memory to be deleted. Found preprocessing 253.perlbmk. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40380 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20At one point there were going to be lexer and parser tokens.Chris Lattner
Since that point is now long gone, we should rename LexerToken to Token, as it is the only kind of token we have. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40105 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20simplify the lexer ctor to take a SLoc instead of a sloc and a redundant ↵Chris Lattner
buffer*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40104 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20Reimplement SourceLocation. Instead of having a Chris Lattner
fileid/offset pair, it now contains a bit discriminating between mapped locations and file locations. This separates the tables for macros and files in SourceManager, and allows better separation of concepts in the rest of the compiler. This allows us to have *many* macro instantiations before running out of 'addressing space'. This is also more efficient, because testing whether something is a macro expansion is now a bit test instead of a table lookup (which also used to require having a srcmgr around, now it doesn't). This is fully functional, but there are several refinements and optimizations left. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40103 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-19Fix a stringizing bug that Neil noticed. We should preprocess this:Chris Lattner
#define t(x) #x t(a c) to "a c", not "ac". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40060 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-15remove obsolete comment.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39868 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-15Change SourceManager::getInstantiationLoc to take virtual locations, doing itsChris Lattner
virtual->physical mapping explicitly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39867 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-15Cache macro expander objects to avoid thrashing malloc in heavy expansion ↵Chris Lattner
situations. This doesn't significantly improve carbon.h, but it does speed up INPUTS/macro_pounder_obj.c by 48% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39864 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-14expose an iterator interface to getReplacementTokens instead of the ↵Chris Lattner
datastructure itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39860 91177308-0d34-0410-b5e6-96231b3b80d8
