2012-02-07Make parsing of objc @implementations more robust.Argyrios Kyrtzidis
Parsing of @implementations was based on modifying global state from the parser; the logic for late parsing of methods was spread in multiple places making it difficult to have a robust error recovery. -it was difficult to ensure that we don't neglect parsing the lexed methods. -it was difficult to setup the original objc container context for parsing the lexed methods after completing ParseObjCAtImplementationDeclaration and returning to top level context. Enhance parsing of @implementations by centralizing it in Parser::ParseObjCAtImplementationDeclaration(). ParseObjCAtImplementationDeclaration now returns only after an @implementation is fully parsed; all the data and logic for late parsing of methods is now in one place. This allows us to provide code-completion for late parsed methods with mis-matched braces. rdar://10775381 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149987 91177308-0d34-0410-b5e6-96231b3b80d8

parsing or false to abort parsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144943 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-25Introduce a -cc1 option "-emit-module", that creates a binary moduleDouglas Gregor
from the given source. -emit-module behaves similarly to -emit-pch, except that Sema is somewhat more strict about the contents of -emit-module. In the future, there are likely to be more interesting differences. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138595 91177308-0d34-0410-b5e6-96231b3b80d8

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
