2012-01-12[analyzer] Add taint transfer by strcpy & others (part 1).Anna Zaks
To simplify the process: Refactor taint generation checker to simplify passing the information on which arguments need to be tainted from pre to post visit. Todo: We need to factor out the code that sema is using to identify the string and memcpy functions and use it here and in the CString checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148010 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-11Fix the caching in CorrectTypo so that other non-keyword identifiersKaelyn Uhrain
are still added if the cached correction fails validation. Also fix a copy-and-paste error in a comment from my previous commit. Finally, add an example of the benefit the typo correction callback adds to TryNamespaceTypoCorrection--which happens to also tickle the above caching problem, as the only way a non-namespace Decl would be added to the possible corrections is if it was cached as the correction for a previous instance of the same typo where the typo was corrected to a non-namespace via a different code path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147968 91177308-0d34-0410-b5e6-96231b3b80d8

Also includes two examples of the callback: a wrapper/replacement for the CorrectTypoContext enum, and a conversion of the two calls to CorrectTypo in SemaDeclCXX.cpp (one of which provides verifiable improvement to the typo correction, as demonstrated in the added test). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147962 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-11Remove '#if 0' from ExprEngine::InlineCall(), and start fresh by wiring up ↵Ted Kremenek
inlining for straight C calls. My hope is to reimplement this from first principles based on the simplifications of removing unneeded node builders and re-evaluating how C++ calls are handled in the CFG. The hope is to turn inlining "on-by-default" as soon as possible with a core set of things working well, and then expand over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147904 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-10The `-fwritable-strings' flag doesn't make the backing store strings of allBill Wendling
CFStrings writable. The strings (both Unicode and ASCII) should reside in a read-only section. E.g., __TEXT,__cstring instead of __DATA,__data.
