2007-10-09Make a significant change to invert the control flow handlingChris Lattner
predefined macros. Previously, these were handled by the driver, now they are handled by the preprocessor. Some fallout of this: 1. Instead of preprocessing two buffers (the predefines, then the main source file) we now start preprocessing the main source file and inject the predefines as a "psuedo #include" from the main source file. 2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify Preprocessor::isInPrimaryFile. 3. The driver doesn't have to know about standard #defines, the preprocessor knows, which is nice for people wanting to define their own drivers. 4. This allows us to put normal tokens in the predefine buffer, for example a definition for __builtin_va_list that is target-specific, and a typedef for id in objc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42818 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07move IdentifierTable.h from liblex to libbasic.Chris Lattner

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
2007-10-05Layering refinements for selectors (suggested by Chris). Specifics...Steve Naroff
- Add SelectorTable, which enables us to remove MultiKeywordSelector from the public header. - Remove FoldingSet from IdentifierInfo.h and Preprocessor.h. - Remove Parser::ObjcGetUnarySelector and Parser::ObjcGetKeywordSelector, they are subsumed by SelectorTable. - Add MultiKeywordSelector to IdentifierInfo.cpp. - Move a bunch of selector related methods from ParseObjC.cpp to IdentifierInfo.cpp. - Added some comments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42643 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-28Yesterday I discovered that 78% of all selectors in "Cocoa.h" take 0/1 argument.Steve Naroff
This motivated implementing a devious clattner inspired solution:-) This approach uses a small value "Selector" class to point to an IdentifierInfo for the 0/1 case. For multi-keyword selectors, we instantiate a MultiKeywordSelector object (previously known as SelectorInfo). Now, the incremental cost for selectors is only 24,800 for Cocoa.h! This saves 156,592 bytes, or 86%!! The size reduction is also the result of getting rid of the AST slot, which was not strictly necessary (we will associate a selector with it's method using another table...most likely in Sema). This change was critical to make now, before we have too many clients. I still need to add some comments to the Selector class...will likely add later today/tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42452 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-27Add SelectorInfo (similar in spirit to IdentifierInfo). The key difference ↵Steve Naroff
is SelectorInfo is not string-oriented, it is a unique aggregate of IdentifierInfo's (using a folding set). SelectorInfo also has a richer API that simplifies the parser/action interface. 3 noteworthy benefits: #1: It is cleaner. I never "liked" storing keyword selectors (i.e. foo:bar:baz) in the IdentifierTable. #2: It is more space efficient. Since Cocoa keyword selectors can be quite long, this technique is space saving. For Cocoa.h, pulling the keyword selectors out saves ~180k. The cost of the SelectorInfo data is ~100k. Saves ~80k, or 43%. #3: It results in many API simplifications. Here are some highlights: - Removed 3 actions (ActOnKeywordMessage, ActOnUnaryMessage, & one flavor of ObjcBuildMethodDeclaration that was specific to unary messages). - Removed 3 funky structs from DeclSpec.h (ObjcKeywordMessage, ObjcKeywordDecl, and ObjcKeywordInfo). - Removed 2 ivars and 2 constructors from ObjCMessageExpr (fyi, this space savings has not been measured). I am happy with the way it turned out (though it took a bit more hacking than I expected). Given the central role of selectors in ObjC, making sure this is "right" will pay dividends later. Thanks to Chris for talking this through with me and suggesting this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42395 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

specifying the start of a token and a logical (phase 3) character number, returns a sloc representing the input character corresponding to it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39905 91177308-0d34-0410-b5e6-96231b3b80d8
