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

by the BAA pass, which uses the default TargetLibraryInfo constructor. Unfortunately, the default TargetLibraryInfo constructor assumes all library calls are available and thus ignores -fno-builtin. rdar://10947759 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151745 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-29[analyzer] Malloc: A pointer might escape through CFContainers APIs,Anna Zaks
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). Malloc, KeyChainAPI and RetainRelease checkers could all use it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151737 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-29Reapply r151638 and r151641.James Molloy
The bug that was caught by Apple's internal buildbots was valid and also showed another bug in my implementation. These are now fixed, with regression tests added to catch them both (not Darwin-specific).
