2011-05-17Fix a nasty bug where inside StringLiteralParser:Argyrios Kyrtzidis
1. We would assume that the length of the string literal token was at least 2 2. We would allocate a buffer with size length-2 And when the stars aligned (one of which would be an invalid source location due to stale PCH) The length would be 0 and we would try to allocate a 4GB buffer. Add checks for this corner case and a bunch of asserts. (We really really should have had an assert for 1.). Note that there's no test case since I couldn't get one (it was major PITA to reproduce), maybe later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131492 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-29Implement C++0x user-defined string literals.Sean Hunt
The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112458 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Introduce optional "Invalid" parameters to routines that invoke theDouglas Gregor
SourceManager's getBuffer() and, therefore, could fail, along with Preprocessor::getSpelling(). Use the Invalid parameters in the literal parsers (string, floating point, integral, character) to make them robust against errors that stem from, e.g., PCH files that are not consistent with the underlying file system. I still need to audit every use caller to all of these routines, to determine which ones need specific handling of error conditions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98608 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

2009-04-28Get rid of some useless uses of NoExtensions. The philosophy here is Eli Friedman
that if we're going to print an extension warning anyway, there's no point to changing behavior based on NoExtensions: it will only make error recovery worse. Note that this doesn't cause any behavior change because NoExtensions isn't used by the current front-end. I'm still considering what to do about the remaining use of NoExtensions in IdentifierTable.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70273 91177308-0d34-0410-b5e6-96231b3b80d8
