* Move clang tests that depend on llvm/ADT/Statistic.h to a subdir.Jan Wen Voung2013-03-081-16/+0
| | | | | | | | | | The subdirectory has a lit.local.cfg that marks the tests unsupported if llvm was built without Asserts. There will be a patch in LLVM that disables statistics gathering when built without Asserts so that full Release builds can be faster. Statistics can also be enabled by building with -DLLVM_ENABLE_STATS. llvm-svn: 176730

* [analyzer] Optimization heuristic: do not reanalyze every ObjC method asAnna Zaks2012-12-071-1/+1
| | | | | | | | | | | | | | | | | | top level. This heuristic is already turned on for non-ObjC methods (inlining-mode=noredundancy). If a method has been previously analyzed, while being inlined inside of another method, do not reanalyze it as top level. This commit applies it to ObjCMethods as well. The main caveat here is that to catch the retain release errors, we are still going to reanalyze all the ObjC methods but without inlining turned on. Gives 21% performance increase on one heavy ObjC benchmark, which suffered large performance regressions due to ObjC inlining. llvm-svn: 169639
* [analyzer] -analyzer-ipa=inlining is now the default. Remove it from tests.Jordan Rose2012-08-211-1/+1
| | | | | | | | | | | | | The actual change here is a little more complicated than the summary above. What we want to do is have our generic inlining tests run under whatever mode is the default. However, there are some tests that depend on the presence of C++ inlining, which still has some rough edges. These tests have been explicitly marked as -analyzer-ipa=inlining in preparation for a new mode that limits inlining to C functions and blocks. This will be the default until the false positives for C++ have been brought down to manageable levels. llvm-svn: 162317
* [analyzer] PCH deserialization optimization.Anna Zaks2012-04-121-0/+17
We should not deserialize unused declarations from the PCH file. Achieve this by storing the top level declarations during parsing (HandleTopLevelDecl ASTConsumer callback) and analyzing/building a call graph only for those. Tested the patch on a sample ObjC file that uses PCH. With the patch, the analyzes is 17.5% faster and clang consumes 40% less memory. Got about 10% overall build/analyzes time decrease on a large Objective C project. A bit of CallGraph refactoring/cleanup as well.. llvm-svn: 154625
