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
2012-02-29Allocate TargetLibraryInfo for the CodeGen passes. Otherwise, it's instantiatedChad Rosier
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

2012-02-29Add support for handling captured variables in lambda debug info.Eric Christopher

2012-02-26Ensure that we delete destructors in the right cases. Specifically:Richard Smith
- variant members with nontrivial destructors make the containing class's destructor deleted - check for a virtual destructor after checking for overridden methods in the base class(es) - check for an inaccessible operator delete for a class with a virtual destructor. Do not try to call an anonymous union field's destructor from the destructor of the containing class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151483 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-25CodeGen support for global variables of type std::initializer_list<X>.Sebastian Redl
This emits a backing array with internal linkage and fills it with data, then has the initializer_list point at the array. Dynamic initialization and global destructors are correctly supported. What doesn't work is nested initializer_lists. I have no idea how to get them to work, either. However, these should be very rare, and so I'll just call it a known bug and declare generalized initializers DONE! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151457 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-22Generate an AST for the conversion from a lambda closure type to aDouglas Gregor
block pointer that returns a block literal which captures (by copy) the lambda closure itself. Some aspects of the block literal are left unspecified, namely the capture variable (which doesn't actually exist) and the body (which will be filled in by IRgen because it can't be written as an AST). Because we're switching to this model, this patch also eliminates tracking the copy-initialization expression for the block capture of the conversion function, since that information is now embedded in the synthesized block literal. -1 side tables FTW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151131 91177308-0d34-0410-b5e6-96231b3b80d8
