* Attempt to fix null ASTContext in ASTUnit error pathBen Langmuir2014-04-221-1/+4
| | | | | | | | | We don't need the ASTContext for the diagnostics, only the language options, which we can get from the compiler invocation. It worries me how many categorically different states the ASTUnit class can be in depending on how it is being constructed/used. llvm-svn: 206909
* Allow adding a value to a flag in diagnostics.Diego Novillo2014-04-211-0/+3
| | | | | | | | | | | | | | | | | Summary: This allows callers of Diags.Report() to append a value to the name of the flag associated with the diagnostic. This is useful in cases like the -Rpass flag, where we want the diagnostic to show the name of the pass that matched the pattern. Instead of showing "... [-Rpass]", this allows us to show "... [-Rpass=passname]". Reviewers: rsmith CC: cfe-commits Differential Revision: http://reviews.llvm.org/D3441 llvm-svn: 206826
* Don't build modules with (submodules with) missing headersBen Langmuir2014-04-181-1/+2
| | | | | | | | Unless they are in submodules that aren't available anyway, due to requirements not being met. Also, mark children as unavailable when the parent is. llvm-svn: 206664
* Don't read CompilerInstance fields that don't exist in ASTUnitBen Langmuir2014-04-181-3/+6
| | | | | | | When transferring data from a CompilerInstance in an error path we need to consider cases where the various fields are uninitialized. llvm-svn: 206644
* Teach users of OnDiskHashTable to define hash_value and offset typesJustin Bogner2014-04-181-2/+8
| | | | | | | | This paves the way to making OnDiskHashTable work with hashes that are not 32 bits wide and to making OnDiskHashTable work very large hash tables. The LLVM change to use these types is upcoming. llvm-svn: 206640

* Revert "Move -fms-extensions predefined macros into InitPreprocessor"Reid Kleckner2014-04-161-12/+0
| | | | | | | | | | This reverts commit r206413. This was proposed before, but it's not clear if this is really a good idea: http://reviews.llvm.org/D3034 llvm-svn: 206415
* Move -fms-extensions predefined macros into InitPreprocessorReid Kleckner2014-04-161-0/+12
| | | | | | | If someone on Linux asks for -fms-extensions, there's no reason not to define the feature test macros that MSVC defines. llvm-svn: 206413
* Add support for optimization reports.Diego Novillo2014-04-162-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds a new flag -Rpass=. The flag indicates the name of the optimization pass that should emit remarks stating when it made a transformation to the code. This implements the design I proposed in: https://docs.google.com/document/d/1FYUatSjZZO-zmFBxjOiuOzAy9mhHA8hqdvklZv68WuQ/edit?usp=sharing Other changes: - Add DiagnosticIDs::isRemark(). Use it in printDiagnosticOptions to print "-R" instead of "-W" in the diagnostic message. - In BackendConsumer::OptimizationRemarkHandler, get a SourceLocation object out of the file name, line and column number. Use that location in the call to Diags.Report(). - When -Rpass is used without debug info a note is emitted alerting the user that they need to use -gline-tables-only -gcolumn-info to get this information.

* Honour -ivfsoverlay in ASTUnit to match clangBen Langmuir2014-04-153-33/+62
| | | | | | | This allows code indexing, etc. to use the VFS in the same way as the compiler. llvm-svn: 206309
* Add module name and module map file to -module-file-infoBen Langmuir2014-04-141-0/+7
| | | | llvm-svn: 206217
* Allow multiple modules with the same name to coexist in the module cacheBen Langmuir2014-04-143-13/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To differentiate between two modules with the same name, we will consider the path the module map file that they are defined by* part of the ‘key’ for looking up the precompiled module (pcm file). Specifically, this patch renames the precompiled module (pcm) files from cache-path/<module hash>/Foo.pcm to cache-path/<module hash>/Foo-<hash of module map path>.pcm In addition, I’ve taught the ASTReader to re-resolve the names of imported modules during module loading so that if the header search context changes between when a module was originally built and when it is loaded we can rebuild it if necessary. For example, if module A imports module B first time: clang -I /path/to/A -I /path/to/B ... second time: clang -I /path/to/A -I /different/path/to/B ... will now rebuild A as expected. * in the case of inferred modules, we use the module map file that allowed the inference, not the __inferred_module.map file, since the inferred file path is the same for every inferred module. llvm-svn: 206201

* -fms-extensions: Don't define __PRETTY_FUNCTION__ to __FUNCTION__Reid Kleckner2014-04-071-4/+0
| | | | | | | This reverts r90596 from 2009. Having this macro definition makes Clang strictly less useful with -fms-extensions. llvm-svn: 205729

* ARM64: initial clang support commit.Tim Northover2014-03-291-0/+5
| | | | | | | | | | | This adds Clang support for the ARM64 backend. There are definitely still some rough edges, so please bring up any issues you see with this patch. As with the LLVM commit though, we think it'll be more useful for merging with AArch64 from within the tree. llvm-svn: 205100
* Reapply "OnDiskHashTable: Use EndianStream.h to write little endian ostreams"Justin Bogner2014-03-281-20/+39
| | | | | | | | | | | | | Committed this by accident before it was done last time. Original message: Rather than rolling our own functions to write little endian data to an ostream, we can use the support in llvm's EndianStream.h. No functional change. llvm-svn: 205061
* Revert "OnDiskHashTable: Use EndianStream.h to write little endian ostreams"Justin Bogner2014-03-281-39/+20

* Use the new Windows environment for target detectionSaleem Abdulrasool2014-03-271-34/+44
| | | | | | | | | This follows the LLVM change to canonicalise the Windows target triple spellings. Rather than treating each Windows environment as a single entity, the environments are now modelled properly as an environment. This is a mechanical change to convert the triple use to reflect that change. llvm-svn: 204978
* Support for -Wa,-compress-debug-sections.David Blaikie2014-03-271-0/+1
| | | | | | Also, while I'm here, support -nocompress-debug-sections too. llvm-svn: 204959
* Move the -i[no-]system-prefix options from CC1Options.td to Options.td.Alexander Kornienko2014-03-261-4/+4
| | | | | | | | | | | | | | | | Summary: This allows them to be used without -cc1 the same way as -I and -isystem. Renamed the options to --system-header-prefix=/--no-system-header-prefix to avoid interference with -isystem and make the intent of the option cleaner.

* [msan] -fsanitize-memory-track-origins=[level] flag and docs.Evgeniy Stepanov2014-03-201-2/+2
| | | | | | | | | This change turns -fsanitize-memory-track-origins into -fsanitize-memory-track-origins=[level] flag (keeping the old one for compatibility). Possible levels are 0 (off), 1 (default) and 2 (incredibly detailed). See docs (part of this patch) for more info. llvm-svn: 204346
* Creating a printing policy for "half":Yunzhong Gao2014-03-181-0/+3
| | | | | | | | | | | | Since "half" is an OpenCL keyword and clang accepts __fp16 as an extension for other languages, error messages and metadata (and hence debug info) should refer to the half-precision floating point as "__fp16" instead of "half" when compiling for non-OpenCL languages. This patch creates a new printing policy for half in a similar manner to what is done for bool and wchar_t. Differential Revision: http://llvm-reviews.chandlerc.com/D2952 llvm-svn: 204164
