2010-02-12Fix PR6282: the include guard optimization cannot happen if theChris Lattner
guard macro is already defined for the first occurrence of the header. If it is, the body will be skipped and not be properly analyzed for the include guard optimization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95972 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08When placing an annotation token over an existing annotation token, make ↵Sebastian Redl

2010-02-03don't inform comment handlers about comments in #if 0 blocks,Chris Lattner
doing so invalidates the file guard optimization and is not in the spirit of "#if 0" because it is supposed to completely skip everything, even if it isn't lexically valid. Patch by Abramo Bagnara! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95253 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22Teach CIndex's cursor visitor to restrict its traversal to a specificDouglas Gregor
region of interest (if provided). Implement clang_getCursor() in terms of this traversal rather than using the Index library; the unified cursor visitor is more complete, and will be The Way Forward. Minor other tweaks needed to make this work: - Extend Preprocessor::getLocForEndOfToken() to accept an offset from the end, making it easy to move to the last character in the token (rather than just past the end of the token). - In Lexer::MeasureTokenLength(), the length of whitespace is zero. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94200 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22revert my patch for rdar://7520940 that warns when a published headerChris Lattner
is #included with "foo.h" style syntax instead of framework syntax. It produced too much noise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94120 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-13Add a bunch more feature-checking macros for C++0x features. Some of these areSean Hunt
disabled with the intent that users can start with them now and not have to change a thing to have them work when we implement the features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93312 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93141 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-10Do not parse hexadecimal floating point literals in C++0x mode because they areSean Hunt
incompatible with user-defined literals, specifically with the following form: 0x1p+1 The preprocessing-number token extends only as far as the 'p'; the '+' is not included. Previously we could get away with this extension as p was an invalid suffix, but now with user-defined literals, 'p' might well be a valid suffix and we are forced to consider it as such. This patch also adds a warning in non-0x C++ modes telling the user that this extension is incompatible with C++0x that is enabled by default (previously and with other languages, we warn only with a compliance option such as -pedantic). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93135 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-17reimplement r90860, fixing a couple of problems:Chris Lattner
1. Don't make a copy of LangOptions every time a lexer is created. 2. Don't make CharInfo global mutable state. 3. Fix the implementation to properly treat ^Z as EOF instead of as horizontal whitespace, which matches the semantic implemented by VC++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91586 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15enable reuse of MacroArgs objects. This is a small (2.5%) win Chris Lattner
on PR5610 (2.185 -> 2.130s). The big issue is that this is making insanely huge macro argument lists with over a million tokens in it. The reason that mallco and free are so expensive is that we are actually going to the kernel to get it, and switching to a bump pointer allocator won't change this in an interesting way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91449 91177308-0d34-0410-b5e6-96231b3b80d8
