2015-09-24Improve the printing of ranges when macros are involved.Richard Trieu1-2/+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. Differential Revision: http://reviews.llvm.org/D12379 llvm-svn: 248454
2015-08-14[modules] Add an experimental -cc1 feature to embed the contents of an inputRichard Smith1-0/+7
file in the .pcm files. 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
2015-08-13Add SourceManager::dump() to dump the current set of SLocEntries.Richard Smith1-0/+57

2015-08-12[modules] If loading a .pcm file would cause us to run out of source ↵Richard Smith1-1/+3

2015-04-06Prefer uninitialized memory for scratch space.Benjamin Kramer1-2/+2
No functional change intended. llvm-svn: 234184
2015-03-16Global inline assembler blocks are merged before parsing, so no specificJoerg Sonnenberger1-14/+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
2014-11-19Standardize on StringMap::insert, removing uses of StringMap::GetOrCreateValue.David Blaikie1-11/+5
llvm-svn: 222306
2014-10-26Make VFS and FileManager match the current MemoryBuffer API.Benjamin Kramer1-10/+11
This eliminates converting back and forth between the 3 formats and gives us a more homogeneous interface. llvm-svn: 220657

2014-07-07Remove unused sys/stat.h includesAlp Toker1-1/+0
The facility was abstracted to LLVM in r187364. llvm-svn: 212441
2014-06-27Remove 'const' from MemoryBuffers used through the SourceManagerDavid Blaikie1-26/+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
2014-05-08[C++11] Use 'nullptr'.Craig Topper1-17/+18

2014-04-15[Allocator] Make the ContentCache object actually carry the 8-byteChandler Carruth1-12/+4
alignment constraint rather than using the allocator function's over alignment "feature". This was the only use of the "feature" which I plan to remove next. =] Attaching the alignment to the type seems cleaner and more principled anyways. llvm-svn: 206324

llvm-svn: 195024
2013-09-27SourceManager: Open code isInMainFile.Benjamin Kramer1-0/+30
- We really shouldn't compute line numbers for every file that is asked if it's the main file, it destroys the lazy computation. - Invalid locations are no longer accounted to the main file, no other functionality change. llvm-svn: 191535

2013-04-13Introduce SourceManager::getDecomposedIncludedLoc, that returns the ↵Argyrios Kyrtzidis1-11/+30
"included/expanded in" decomposed location of the given FileID. The main benefit is to speed-up SourceManager::isBeforeInTranslationUnit which is common to query the included/expanded location of the same FileID multiple times. llvm-svn: 179435

2013-02-27Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.Ted Kremenek1-1/+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
2013-02-22Replace some typically large vectors with SmallVector.Benjamin Kramer1-1/+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

Post-commit CR feedback from Jordan Rose regarding r175594. llvm-svn: 175679
2013-01-12Fix -Wunused-comparison for comparisons in arguments to function-like macros.Matt Beaumont-Gay1-2/+9
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
2012-12-16Don't use SourceLineCache in getColumnNumber if LastLineNoResult is past the ↵Craig Topper1-1/+2
end of the cache. Fixes PR14570. llvm-svn: 170281
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-5/+5
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. llvm-svn: 169237
2012-11-14Add -cc1 option -fno-diagnostics-use-presumed-location, a handy mode forRichard Smith1-2/+3
working with preprocessed testcases. This causes source locations in diagnostics to point at the spelling location instead of the presumed location, while still keeping the semantic effects of the line directives (entering and leaving system-header mode, primarily). llvm-svn: 168004
2012-10-20When associating file ranges of macro arguments with theirArgyrios Kyrtzidis1-37/+82

2012-10-19Teach getColumnNumber to use the line cache to get the start of the line if ↵Craig Topper1-0/+11
