2012-12-06[libclang] Introduce a new indexing mode where we skip function bodiesArgyrios Kyrtzidis
that were already parsed in the same "indexing session". An indexing session is defined as using the same CXIndexAction object for multiple clang_indexSourceFile calls. Passing CXIndexOpt_SkipParsedBodiesInSession as an indexing option will enable the mode where we try to skip bodies that were already parsed in another translation unit. If a function's body was skipped, the "flags" field in the CXIdxDeclInfo structure will have "CXIdxDeclFlag_Skipped" bit was set. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169539 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-06[analyzer] Simplify RetainCountChecker's handling of dead symbols.Jordan Rose
Previously we made three passes over the set of dead symbols, and removed them from the state /twice/. Now we combine the autorelease pass and the symbol death pass, and only have to remove the bindings for the symbols that leaked. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169527 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-06[analyzer] Use a smarter algorithm to find the last block in an inlined call.Jordan Rose
Previously we would search for the last statement, then back up to the entrance of the block that contained that statement.

2012-12-06[analyzer] Aggressively cut back on the canonicalization in RegionStore.Jordan Rose
Whenever we touch a single bindings cluster multiple times, we can delay canonicalizing it until the final access. This has some interesting implications, in particular that we shouldn't remove an /empty/ cluster from the top-level map until canonicalization. This is good for a 2% speedup or so on the test case in <rdar://problem/12810842> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169523 91177308-0d34-0410-b5e6-96231b3b80d8

This feature was probably intended to improve diagnostics, but was currently only used when dumping the Environment.

2012-12-06Rework the bitfield access IR generation to address PR13619 andChandler Carruth
generally support the C++11 memory model requirements for bitfield accesses by relying more heavily on LLVM's memory model. The primary change this introduces is to move from a manually aligned and strided access pattern across the bits of the bitfield to a much simpler lump access of all bits in the bitfield followed by math to extract the bits relevant for the particular field. This simplifies the code significantly, but relies on LLVM to intelligently lowering these integers. I have tested LLVM's lowering both synthetically and in benchmarks. The lowering appears to be functional, and there are no really significant performance regressions. Different code patterns accessing bitfields will vary in how this impacts them. The only real regressions I'm seeing are a few patterns where the LLVM code generation for loads that feed directly into a mask operation don't take advantage of the x86 ability to do a smaller load and a cheap zero-extension. This doesn't regress any benchmark in the nightly test suite on my box past the noise threshold, but my box is quite noisy. I'll be watching the LNT numbers, and will look into further improvements to the LLVM lowering as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169489 91177308-0d34-0410-b5e6-96231b3b80d8
