* Improve the printing of ranges when macros are involved.Richard Trieu2015-09-241-2/+7

Also some improvements to backtrace printer for omitting different backtraces. Patch by Zhengkai Wu. Differential Revision: http://reviews.llvm.org/D12379 llvm-svn: 248454

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. llvm-svn: 245028

* Global inline assembler blocks are merged before parsing, so no specificJoerg Sonnenberger2015-03-161-14/+25
| | | | | | | | | | | | | location data is available. If pragma handling wants to look up the position, it finds the LLVM buffer and wants to compare it with the special built-in buffer, failing badly. Extend to the special handling of the built-in buffer to also check for the inline asm buffer. Expect only a single asm buffer. Sort it between the built-in buffers and the normal file buffers. Fixes the assert part of PR 22576. llvm-svn: 232389

* 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. llvm-svn: 211915

* 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. Fixes <rdar://problem/13299847> llvm-svn: 176142
* Replace some typically large vectors with SmallVector.Benjamin Kramer2013-02-221-1/+1
| | | | | | | | This may seem counter-intuitive but the POD-like optimization helps when the vectors grow into multimegabyte buffers. SmallVector calls realloc which knows how to twiddle virtual memory bits and avoids large copies. llvm-svn: 175906

| | | | | | | | | | | Previously, -Wunused-comparison ignored comparisons in both macro bodies and macro arguments, but we would still emit a -Wunused-value warning for either. Now we correctly emit -Wunused-comparison for expressions in macro arguments. Also, add isMacroBodyExpansion to SourceManager, to go along with isMacroArgExpansion. llvm-svn: 172279

* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-5/+5

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. llvm-svn: 169237

* Introduce a flag in SourceManager to treat non-system source filesArgyrios Kyrtzidis2012-07-111-3/+11
| | | | | | | | | | | | | | | | | | | | as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. 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 llvm-svn: 160074
