2012-03-03Frontend: Default to creating output files using temporary files + rename.Daniel Dunbar
- This is a more reliable default, as it behaves better on failure and also ensures that we create *new* files (instead of reusing existing inodes). This is useful for other applications (like lldb) which want to cache inode's to know when a file has been rewritten. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151961 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-03Frontend: Don't automatically create missing directories when using ↵Daniel Dunbar

2012-03-02[analyzer] Rename clang::CallGraph into clang::idx::CallGraph + renameAnna Zaks
the corresponding files to avoid confusion. This is a preparation to adding an AST-based call graph to Analysis. The existing call graph works with indexer entries. We might be able to refactor it to use the AST based graph in the future. (Minimal testing here as the only example that uses the API has been completely broken, does not compile.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151950 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Add a flag -fthread-sanitizer.Kostya Serebryany
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151846 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Implement "optimization" for lambda-to-block conversion which inlines the ↵Eli Friedman
generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap. Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal. With ARC, the effect is much less obvious because the lifetime of blocks is already managed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-29Allow operator keywords to be #defined in ms-ext mode.Nico Weber
Fixes PR10606. I'm not sure if this is the best way to go about it, but I locally enabled this code path without the msext conditional, and all tests pass, except for test/Preprocessor/cxx_oper_keyword.cpp which explicitly checks that operator keywords can't be redefined. I also parsed chromium/win with a clang with and without this patch. It introduced no new errors, but removes 43 existing errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151768 91177308-0d34-0410-b5e6-96231b3b80d8

funopen, setvbuf. Teach the checker and the engine about these APIs to resolve malloc false positives. As I am adding more of these APIs, it is clear that all this should be factored out into a separate callback (for example, region escapes).
