* Add the concept of "modifiers" to the clang diagnostic format Chris Lattner2008-11-213-66/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strings. This allows us to have considerable flexibility in how these things are displayed and provides extra information that allows us to merge away diagnostics that are very similar. Diagnostic modifiers are a string of characters with the regex [-a-z]+ that occur between the % and digit. They may optionally have an argument that can parameterize them. For now, I've added two example modifiers. One is a very useful tool that allows you to factor commonality across diagnostics that need single words or phrases combined. Basically you can use %select{a|b|c}4 with with an integer argument that selects either a/b/c based on an integer value in the range [0..3). The second modifier is also an integer modifier, aimed to help English diagnostics handle plurality. "%s3" prints to 's' if integer argument #3 is not 1, otherwise it prints to nothing. I'm fully aware that 's' is an English concept and doesn't apply to all situations (mouse vs mice). However, this is very useful and we can add other crazy modifiers once we add support for polish! ;-) I converted a couple C++ diagnostics over to use this as an example, I'd appreciate it if others could merge the other likely candiates. If you have other modifiers that you want, lets talk on cfe-dev. llvm-svn: 59803

* move the diagnostic location and ID out of DiagnosticInfo and store it inChris Lattner2008-11-211-8/+13
| | | | | | | | | | the Diagnostic class. Since we can already only have one diagnostic in flight at a time, this shrinks DiagnosticInfo. This reduces DiagnosticInfo to being basically a rather crazy smart pointer to a DiagnosticInfo :) llvm-svn: 59798

* Change -verify mode to find the "expected-error" and "expected-warning" stringsChris Lattner2008-11-212-22/+15
| | | | | | | | with a raw lexer instead of a PP lexer. This means that -verify doesn't scan #include'd headers for expected-error/warning strings, and it also means that it doesn't ignore them in #if 0. llvm-svn: 59774

| | | | | | | | | | - Rename 'CurToken' and 'LastToken' to 'CurTokenIdx' and 'LastTokenIdx' respectively. - Add helper methods GetToken(), AdvanceToken(), AtLastToken() to abstract away details of the token stream. This also allows us to easily replace their implementation later. llvm-svn: 59733

* De-unionize fields in Token class.Daniel Dunbar2008-11-201-25/+25
| | | | | | | | | | | | - This is fairly gross but although the code is conceptually the same, introducting the union causes gcc 4.2 on x86 (darwin, if that matters) to pessimize LexTokenInternal which is critical to our preprocessor performance. This speeds up -Eonly lexing of Cocoa.h by ~4.7% in my timings and reduces the code size of LexTokenInternal by 8.6%. llvm-svn: 59725
* Rewrote PTHLexer::Lex by digging through the sources of Lexer again. Now we ↵Ted Kremenek2008-11-201-28/+37
| | | | | | can do basic macro expansion using the PTHLexer. llvm-svn: 59724
* Add ugly "test harness" for PTHLexer that is not enabled by default. TheTed Kremenek2008-11-201-6/+49
| | | | | | | | | | (temporary hack) to test the PTHLexer is that whenever we would create a Lexer object we instead raw lex a memory buffer first and then use the PTHLexer. This logic exists only to driver the PTHLexer and will be removed/changed in the future. Note that the regular path using normal Lexer objects is what is used by default. llvm-svn: 59723
* Added virtual method 'IndirectLex' to PTHLexer. This will likely get ↵Ted Kremenek2008-11-201-0/+4

* remove the type_info identifier cache. Compared to the costChris Lattner2008-11-203-17/+7
| | | | | | | | | | | of doing the lookup_decl, the hash lookup is cheap. Also, typeid doesn't happen enough in real world code to worry about it. I'd like to eventually get rid of KnownFunctionIDs from Sema also, but today is not that day. llvm-svn: 59711
* compared to the rest of the code in Sema::GetStdNamespace(),Chris Lattner2008-11-203-3/+2
| | | | | | | looking up the "std" identifier is trivial. Just do it, particularly since this is only done if the namespace hasn't already been looked up. llvm-svn: 59710
