2013-03-25Try harder to be signal-safe inside our signal handler. The most prominent ↵Nick Lewycky
behavioural difference is that we no longer clean the token before emitting it. This fixes a bug where clang hangs in the middle of crashing because the crash handler calls malloc from inside a crash that happened inside of free. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177919 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-27Move PrettyStackTraceParserEntry to ParseAST.cppNico Weber
r128056 moved PrettyStackTraceParserEntry construction from Parser.h to ParseAST.cpp, so there's no need to keep this class in a header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168731 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-05Have the parser initialize Sema before it consumes the firstDouglas Gregor
token. This is important because the first token could actually be after an #include that triggers a module import, which might use either Sema or the AST consumer before it would have been initialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167423 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-04Drop the ASTContext.h include from Stmt.h and fix up transitive users.Benjamin Kramer
This required moving the ctors for IntegerLiteral and FloatingLiteral out of line which shouldn't change anything as they are usually called through Create methods that are already out of line. ASTContext::Deallocate has been a nop for a long time, drop it from ASTVector and make it independent from ASTContext.h Pass the StorageAllocator directly to AccessedEntity so it doesn't need to have a definition of ASTContext around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159718 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Revert predefined decl tracking.Meador Inge
r158085 added some logic to track predefined declarations. The main reason we had predefined declarations in the input was because the __builtin_va_list declarations were injected into the preprocessor input. As of r158592 we explicitly build the __builtin_va_list declarations. Therefore the predefined decl tracking is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158732 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-06Add pedantic warning -Wempty-translation-unit (C11 6.9p1).Jordan Rose
In standard C since C89, a 'translation-unit' is syntactically defined to have at least one "external-declaration", which is either a decl or a function definition. In Clang the latter gives us a declaration as well. The tricky bit about this warning is that our predefines can contain external declarations (__builtin_va_list and the 128-bit integer types). Therefore our AST parser now makes sure we have at least one declaration that doesn't come from the predefines buffer. Also, remove bogus warning about empty source files. This doesn't catch source files that only contain comments, and never fired anyway because of our predefines.

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

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.

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
