2009-05-25Fix a couple of bugs:Chris Lattner
1. When we accept "#garbage" in asm-with-cpp mode, change the token kind of the # to unknown so that the preprocessor won't try to process it as a real #. This fixes a crash on the attached example 2. Fix macro definition extents processing to handle #foo at the end of a macro to say the definition ends with the foo, not the #. This is a follow-on fix to r72283, and rdar://6916026 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72388 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-19Fix PR4006, incorrect handling of __VA_ARGS__ when it was the first tokenChris Lattner
in a function-like macro body. This has the added bonus of moving some function-like macro specific code out of the object-like macro codepath. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69530 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18more fun with line markers: the digit string is required to be interpretedChris Lattner

2009-03-18when preprocessing a .S file, unknown directives should just be passed through,Chris Lattner
and the token after the # should be expanded if it is not a valid directive.

2009-01-26remove my hacks that aggressively threw away multiple Chris Lattner
instantiation history in an effort to speed up c99-intconst-1.c. Now that multiple nested instantiations are allowed, we just make them and don't pay the cost of lookups. With the other changes that went in before this, reverting this is actually a speedup for c99-intconst-1.c, speeding it up from 1.96s to 1.80s, and preserves much better loc info. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63036 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-26parse and enforce required constraints on #line directives. Right nowChris Lattner
we just discard them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62999 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Eagerly resolve the spelling location of the tokens in a definitionChris Lattner
of a macro. Since these tokens may themselves be from macro expansions, we need to resolve down to the spelling loc when the macro ends up being instantiated. Instead of resolving this for each token expanded from the macro definition, just do it once when the macro is defined. This speeds up clang on c99-intconst-1.c from 2.66s to 2.43s (9.5%), reducing the FileID lookups from 407244 linear and 114175649 binary to 2529040 linear and 64771121 binary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62993 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19do not use SourceManager::getFileCharacteristic(FileID), it is notChris Lattner
safe because a #line can change the file characteristic on a per-loc basis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62501 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16As a performance optimization, don't bother calling MacroInfo::isIdenticalTo Chris Lattner
if warnings in system headers are disabled. isIdenticalTo can end up calling the expensive getSpelling method, and other bad stuff and is completely unneeded if the warning will be discarded anyway. rdar://6502956 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62347 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-23PTH:Ted Kremenek
- Embed 'eom' tokens in PTH file. - Use embedded 'eom' tokens to not lazily generate them in the PTHLexer. This means that PTHLexer can always advance to the next token after reading a token (instead of buffering tokens using a copy). - Moved logic of 'ReadToken' into Lex. GetToken & ReadToken no longer exist. - These changes result in a 3.3% speedup (-Eonly) on Cocoa.h. - The code is a little gross. Many cleanups are possible and should be done. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61360 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-15Preprocessor: Allocate MacroInfo objects using a BumpPtrAllocator instead ↵Ted Kremenek
