2011-07-06Build up statistics about the work done for analysis based warnings.Chandler Carruth
Special detail is added for uninitialized variable analysis as this has serious performance problems than need to be tracked. Computing some of this data is expensive, for example walking the CFG to determine its size. To avoid doing that unless the stats data is going to be used, we thread a bit into the Sema object to track whether detailed stats should be collected or not. This bit is used to avoid computations whereever the computations are likely to be more expensive than checking the state of the flag. Thus, counters are in some cases unconditionally updated, but the more expensive (and less frequent) aggregation steps are skipped. With this patch, we're able to see that for 'gcc.c': *** Analysis Based Warnings Stats: 232 functions analyzed (0 w/o CFGs). 7151 CFG blocks built. 30 average CFG blocks per function. 1167 max CFG blocks per function. 163 functions analyzed for uninitialiazed variables 640 variables analyzed. 3 average variables per function. 94 max variables per function. 96409 block visits. 591 average block visits per function. 61546 max block visits per function. And for the reduced testcase in PR10183: *** Analysis Based Warnings Stats: 98 functions analyzed (0 w/o CFGs). 8526 CFG blocks built. 87 average CFG blocks per function. 7277 max CFG blocks per function. 68 functions analyzed for uninitialiazed variables 1359 variables analyzed. 19 average variables per function. 1196 max variables per function. 2540494 block visits. 37360 average block visits per function. 2536495 max block visits per function. That last number is the somewhat scary one that indicates the problem in PR10183. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134494 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06When tree-transforming an expression sequence, always flag expandedJohn McCall
variadic argument pack expansions as having changed, rather than doing it for each changed expansion, which leaves out zero-argument packs with catastrophic consequences. Fixes PR10260. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134483 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-06Fixed enum types can be complete without actually being valid to useJohn McCall

2011-07-06Improve the Python bindings for libclang in a few ways, from EliDouglas Gregor
Bendersky. Specifically: * Implemented a new function in libclang: clang_isAttribute * Fixing TranslationUnit.get_includes to only go through the argument * buffer when it contains something. This fixed a crash on Windows * clang_getFileName returns CXString, not char*. Made appropriate * fixes in cindex.py - now the relevant tests pass and we can see the * full locations correctly again (previously there was garbage in * place of the file name) * Exposed clang_getCursorDisplayName to the python bindings git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134460 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Call objc_terminate() instead of abort() when a cleanup throws anJohn McCall
exception in Objective-C; in Objective-C++ we still use std::terminate(). This is only available in very recent runtimes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134456 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8
