* [analyzer] Don't process autorelease counts in synthesized function bodies.Jordan Rose2013-08-012-3/+409
| | | | | | | | | | | | | | | We process autorelease counts when we exit functions, but if there's an issue in a synthesized body the report will get dropped. Just skip the processing for now and let it get handled when the caller gets around to processing autoreleases. (This is still suboptimal: objects autoreleased in the caller context should never be warned about when exiting a callee context, synthesized or not.) Second half of <rdar://problem/14611722> llvm-svn: 187625
* [analyzer] Silently drop all reports within synthesized bodies.Jordan Rose2013-08-012-157/+196
| | | | | | | | | | | | | | | | | | | | | Much of our diagnostic machinery is set up to assume that the report end path location is valid. Moreover, the user may be quite confused when something goes wrong in our BodyFarm-synthesized function bodies, which may be simplified or modified from the real implementations. Rather than try to make this all work somehow, just drop the report so that we don't try to go on with an invalid source location. Note that we still handle reports whose /paths/ go through invalid locations, just not those that are reported in one. We do have to be careful not to lose warnings because of this. The impetus for this change was an autorelease being processed within the synthesized body, and there may be other possible issues that are worth reporting in some way. We'll take these as they come, however. <rdar://problem/14611722> llvm-svn: 187624

* Use llvm::sys::fs::UniqueID for windows and unix.Rafael Espindola2013-08-0110-249/+197
| | | | | | | | | | | | | | | | | | | This unifies the unix and windows versions of FileManager::UniqueDirContainer and FileManager::UniqueFileContainer by using UniqueID. We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we want to be able to construct fake ones, and file_status has different members on unix and windows. What the patch does is: * Record only the information that clang is actually using. * Use llvm::sys::fs::status instead of stat and fstat. * Use llvm::sys::fs::UniqueID * Delete the old windows versions of UniqueDirContainer and UniqueFileContainer since the "unix" one now works on windows too. llvm-svn: 187619

* DebugInfo: Don't prefer declarations over definitions in -flimit-debug-info in CDavid Blaikie2013-08-013-7/+17
| | | | | | | | | Without an ODR, the -flimit-debug-info debug info size optimization of emitting declarations for fully defined types when only a declaration is needed by the TU, is incorrect. Emit the full definition whenever it's available in non-C++. llvm-svn: 187611
* DebugInfo: Emit template arguments for limited types used for context.David Blaikie2013-08-012-11/+14
| | | | | | | | We emit definitions with no members when a nested type is referenced/required (GCC does the same, to be fair) but failed to attach the template arguments in such a case. llvm-svn: 187608

* With help from chapuni on IRC, I think this is right now. =] The issueChandler Carruth2013-07-311-8/+8
| | | | | | | | | | | | | | | | is that the command is quoted differently from the arguments. The command has '\' and the argument has '\\'. This is made unclear because FileCheck escapes the single matched '\' when it prints the contents of the variable, thus fooling me into thinking it had matched '\\' as intended. The solution is to bind the gcc_install variable in the argument list rather than out of the command. To do so we also have to be a bit more careful so that we don't get stray other things into the '.*' regex. Also, because of the argument difference, '\\\\' is the correct formulation before crtbegin, go back to that. llvm-svn: 187489
