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

We creating and free thousands of MacroArgs objects (and the related std::vectors hanging off them) for the testcase in PR5610 even though there are only ~20 live at a time.

2009-12-02Extend the source manager with the ability to override the contents ofDouglas Gregor
files with the contents of an arbitrary memory buffer. Use this new functionality to drastically clean up the way in which we handle file truncation for code-completion: all of the truncation/completion logic is now encapsulated in the preprocessor where it belongs (<rdar://problem/7434737>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90300 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01pass the reason for failure up from MemoryBuffer and report itChris Lattner

2009-11-30Fix PR5633 by making the preprocessor handle the case where we canChris Lattner
stat a file but where mmaping it fails. In this case, we emit an error like: t.c:1:10: fatal error: error opening file '../../foo.h' instead of "cannot find file". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90110 91177308-0d34-0410-b5e6-96231b3b80d8
