* Improve the printing of ranges when macros are involved.Richard Trieu2015-09-241-2/+7
| | | | | | | | | | | | | Trace the ranges through the macro backtrace better. This allows better range highlighting through all levels of the macro bracktrace. Also some improvements to backtrace printer for omitting different backtraces. Patch by Zhengkai Wu.

This allows a smaller set of files to be sent to a remote build worker when building with explicit modules (for instance, module map files need not be sent along with the corresponding precompiled modules). This doesn't actually make the embedded files visible to header search, so it's not useful as a packaging format for public header files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@245028 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove 'const' from MemoryBuffers used through the SourceManagerDavid Blaikie2014-06-271-26/+21
| | | | | | | | | | | | | | This removes a const_cast added in r211884 that occurred due to an inconsistency in how MemoryBuffers are handled between some parts of clang and LLVM. MemoryBuffers are immutable and the general convention in the LLVM project is to omit const from immutable types as it's simply redundant/verbose (see llvm::Type, for example). While this change doesn't remove "const" from /every/ MemoryBuffer, it at least makes this chain of ownership/usage consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211915 91177308-0d34-0410-b5e6-96231b3b80d8

* Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.Ted Kremenek2013-02-271-1/+31
| | | | | | | | | | | | | | | | | | | | | | isBeforeInTranslationUnit() uses a cache to reduce the expensive work to compute a common ancestor for two FileIDs. This work is very expensive, so even caching the latest used FileIDs was a big win. A closer analysis of the cache before, however, shows that the cache access pattern would oscillate between a working set of FileIDs, and thus caching more pairs would be profitable. This patch adds a side table for extending caching. This side table is bounded in size (experimentally determined in this case from a simple Objective-C project), and when the table gets too large we fall back to the single entry caching before as before. On Sketch (a small example Objective-C project), this optimization reduces -fsyntax-only time on SKTGraphicView.m by 5%. This is for a project that is already using PCH.

Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160074 91177308-0d34-0410-b5e6-96231b3b80d8
