2012-11-16[libclang] When caching code-completion results, pass the ↵Argyrios Kyrtzidis
CachedCompletionAllocator to the CodeCompletionTUInfo that is going to be used to get the results. Previously we would use ASTUnit's CodeCompletionTUInfo which has its own allocator that will go away when we reparse. That could result in a use-after-free bug when getting the parent context name from a CodeCompletionString.

2012-11-05Frontend: Add support for reading named pipes as the main file.Daniel Dunbar

2012-11-05Add -fsanitize=<sanitizers> argument to driver and frontend, and addRichard Smith

Right now, the different modes can't be combined, but the intention is that combining UBSan and the other sanitizers will be permitted in the near future. Currently, the UBSan checks will all be enabled if any of them is; that will be fixed by the next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167411 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-31[PCH] Remove the stat cache from the PCH file.Argyrios Kyrtzidis
The stat cache became essentially useless ever since we started validating all file entries in the PCH. But the motivating reason for removing it now is that it also affected correctness in this situation: -You have a header without include guards (using "#pragma once" or #import) -When creating the PCH: -The same header is referenced in an #include with different filename cases. -In the PCH, of course, we record only one file entry for the header file -But we cache in the PCH file the stat info for both filename cases -Then the source files are updated and the header file is updated in a way that its size and modification time are the same but its inode changes -When using the PCH: -We validate the headers, we check that header file and we create a file entry with its current inode -There's another #include with a filename with different case than the previously created file entry -In order to get its stat info we go through the cached stat info of the PCH and we receive the old inode -because of the different inodes, we think they are different files so we go ahead and include its contents. Removing the stat cache will potentially break clients that are attempting to use the stat cache as a way of avoiding having the actual input files available. If that use case is important, patches are welcome to bring it back in a way that will actually work correctly (i.e., emit a PCH that is self-contained, coping with literal strings, line/column computations, etc.).

2012-10-24Teach the PCH validator to check the preprocessor options, especiallyDouglas Gregor
the macros that are #define'd or #undef'd on the command line. This checking happens much earlier than the current macro-definition checking and is far cleaner, because it does a direct comparison rather than a diff of the predefines buffers. Moreover, it allows us to use the result of this check to skip over PCH files within a directory that have non-matching -D's or -U's on the command line. Finally, it improves the diagnostics a bit for mismatches, fixing <rdar://problem/8612222>. The old predefines-buffer diff'ing will go away in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166641 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-23[analyzer] Replace -analyzer-no-eagerly-trim-egraph with graph-trim-interval.Jordan Rose
After every 1000 CFGElements processed, the ExplodedGraph trims out nodes that satisfy a number of criteria for being "boring" (single predecessor, single successor, and more). Rather than controlling this with a cc1 option, which can only disable this behavior, we now have an analyzer-config option, 'graph-trim-interval', which can change this interval from 1000 to something else. Setting the value to 0 disables reclamation. The next commit relies on this behavior to actually test anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166528 91177308-0d34-0410-b5e6-96231b3b80d8
