* Fix diagnostic pragmas.Argyrios Kyrtzidis2010-12-151-9/+5
| | | | | | | | | | | | Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state. Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect a lot of places, like C++ inline methods, template instantiations, the lexer, etc. Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location. Fixes rdar://8365684. llvm-svn: 121873
* push some source location information down through the compiler,Chris Lattner2010-04-201-8/+12

* Introduce a new BufferResult class to act as the return type ofDouglas Gregor2010-03-151-3/+3
| | | | | | | | | | | | | | SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). llvm-svn: 98585

* track "just a little more" location information for macro instantiations.Chris Lattner2009-02-151-3/+4
| | | | | | | | | | | | Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. llvm-svn: 64601

| | | | | | | | | | | | | | | "FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. llvm-svn: 62407

* PreprocessorLexer (and subclasses):Ted Kremenek2008-12-101-10/+2
| | | | | | | | - Added virtual method 'getSourceLocation()' (no arguments) that gets the location of the next "observable" location (e.g., next character, next token). PPLexerChange.cpp: - Implemented FIXME by using PreprocessorLexer::getSourceLocation() to get the location in the file we are returning to after lexing a #included file. This appears to be slightly faster than having the branch (i.e., 'if(CurLexer)'). It's also not a really hot part of the Preprocessor. llvm-svn: 60860
* Preprocessor:Ted Kremenek2008-12-021-2/+32
| | | | | | | | | - Added method "setPTHManager" that will be called by the driver to install a PTHManager for the Preprocessor. - Fixed some comments. - Added EnterSourceFileWithPTH to mirror EnterSourceFileWithLexer. llvm-svn: 60437

| | | | | | | | | | (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

* - Add Lexer::isPragma() accessor for clients of Lexer that aren't friends.Ted Kremenek2008-11-181-8/+14
| | | | | | | | | - Add static method to test if the current lexer is a non-macro/non-pragma lexer. - Refactor some code in PPLexerChange to use this static method. - No performance change. llvm-svn: 59486

* Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfoChris Lattner2008-09-261-13/+9
| | | | | | | | | | | to whether the fileid is a 'extern c system header' in addition to whether it is a system header, most of this is spreading plumbing around. Once we have that, PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to base the system header state on FileIDInfo instead of HeaderSearch. Finally, in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness of a file being entered can be set due to the #includer or the #includee. llvm-svn: 56688
* More #include cleaningDaniel Dunbar2008-08-111-1/+0
| | | | | | | | | | | - Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. llvm-svn: 54632
