* Change MemoryBuffer* to MemoryBuffer& parameter to Lexer::ComputePreambleDavid Blaikie2014-08-111-4/+4
| | | | | | | | | | | | | (dropping const from the reference as MemoryBuffer is immutable already, so const is just redundant - and while I'd personally put const everywhere, that's not the LLVM Way (see llvm::Type for another example of an immutable type where "const" is omitted for brevity)) Changing the pointer argument to a reference parameter makes call sites identical between callers with unique_ptrs or raw pointers, minimizing the churn in a pending unique_ptr migrations. llvm-svn: 215391
* Recommit 213307: unique_ptr-ify ownership of ASTConsumers (reverted in r213325)David Blaikie2014-08-101-15/+17
| | | | | | | | After post-commit review and community discussion, this seems like a reasonable direction to continue, making ownership semantics explicit in the source using the type system. llvm-svn: 215323

* Revert "unique_ptr-ify ownership of ASTConsumers"David Blaikie2014-07-171-17/+15
| | | | | | | | | This reverts commit r213307. Reverting to have some on-list discussion/confirmation about the ongoing direction of smart pointer usage in the LLVM project. llvm-svn: 213325
* unique_ptr-ify ownership of ASTConsumersDavid Blaikie2014-07-171-15/+17
| | | | | | | | | (after fixing a bug in MultiplexConsumer I noticed the ownership of the nested consumers was implemented with raw pointers - so this fixes that... and follows the source back to its origin pushing unique_ptr ownership up through there too) llvm-svn: 213307
* Remove unused sys/stat.h includesAlp Toker2014-07-071-1/+0
| | | | | | The facility was abstracted to LLVM in r187364. llvm-svn: 212441
* Peel away old-style file remapping typedefs and cruftAlp Toker2014-07-071-52/+30
| | | | llvm-svn: 212438
* Use non-intrusive refcounting for TargetOptionsAlp Toker2014-07-061-21/+18
| | | | llvm-svn: 212388
* Use non-intrusive refcounting for LangOptionsAlp Toker2014-07-061-2/+2
| | | | | | | This type is only refcounted in a couple of places so making ownership explicit improves clarity. llvm-svn: 212387
* Constify a read-only parameter and give function a better nameAlp Toker2014-07-061-5/+5
| | | | | | | This makes it clear that TargetInfo doesn't capture the LangOptions object, rather uses it to apply adjustments. llvm-svn: 212386
* Track IntrusiveRefCntPtr::get() changes from LLVM r212366Alp Toker2014-07-051-7/+7
| | | | llvm-svn: 212369
* Consider module depedencies when checking a preamble in libclangBen Langmuir2014-06-301-15/+9
| | | | | | | | | | | | | Add module dependencies (header files, module map files) to the list of files to check when deciding whether to rebuild a preamble. That fixes using preambles with module imports so long as they are in non-overridden files. My intent is to use to unify the existing dependency collectors to the new “DependencyCollectory” interface from this commit, starting with the DependencyFileGenerator. llvm-svn: 212060
* Stop sharing the FileManager in ASTUnit::ParseBen Langmuir2014-06-231-1/+7
| | | | | | | | | | We were using old stat values for any files that had previously been looked up, leading to badness. There might be a more elegant solution in invalidating the cache for those file (since we already know which ones they are), but it seems too likely there are existing references to them hiding somewhere. llvm-svn: 211504

| | | | llvm-svn: 209389
* Eliminate ASTContext's DelayInitialization flagAlp Toker2014-05-031-8/+3
| | | | | | | | | Having various possible states of initialization following construction doesn't add value here. Also remove the unused size_reserve parameter. llvm-svn: 207897
* Reformat code following Preprocessor constructor updatesAlp Toker2014-05-021-6/+5
| | | | | | Landing this separately to make the previous commits easy to follow at home. llvm-svn: 207826
* Factor TargetInfo pointer/DelayInitialization bool pair out of Preprocessor ctorAlp Toker2014-05-021-3/+2
| | | | | | | | The Preprocessor::Initialize() function already offers a clear interface to achieve this, further reducing the confusing number of states a newly constructed preprocessor can have. llvm-svn: 207825

* 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
* 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
* Honour -ivfsoverlay in ASTUnit to match clangBen Langmuir2014-04-151-8/+27
| | | | | | | This allows code indexing, etc. to use the VFS in the same way as the compiler. llvm-svn: 206309

* [libclang] Don't pad the main buffer for the preamble.Argyrios Kyrtzidis2014-03-091-40/+6
| | | | | | | | | Padding does not seem to be useful currently, and it leads to bogus location if an error points to the end of the file. rdar://15836513 llvm-svn: 203370

* [ASTUnit] Fix use-after-free bug in ↵Argyrios Kyrtzidis2014-02-271-22/+8
| | | | | | | | | | | | | | | ASTUnit::getMainBufferWithPrecompiledPreamble(). With r197755 we started reading the contents of buffer file entries, but the buffers may point to ASTReader blobs that have been disposed. Fix this by having the CompilerInstance object keep a reference to the ASTReader as well as having the ASTContext keep reference to the ExternalASTSource. This was very difficult to construct a test case for. rdar://16149782 llvm-svn: 202346
* Recommit virtual file systemBen Langmuir2014-02-201-3/+3
| | | | | | | | | | | Previously reverted in r201755 due to causing an assertion failure. I've removed the offending assertion, and taught the CompilerInstance to create a default virtual file system inside createFileManager. In the future, we should be able to reach into the CompilerInvocation to customize this behaviour without breaking clients that don't care. llvm-svn: 201818

* Use the same SourceManager for ModuleMaps and compilations.Manuel Klimek2013-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows using virtual file mappings on the original SourceManager to map in virtual module.map files. Without this patch, the ModuleMap search will find a module.map file (as the FileEntry exists in the FileManager), but will be unable to get the content from the SourceManager (as ModuleMap previously created its own SourceManager). Two problems needed to be fixed which this patch exposed: 1. Storing the inferred module map When writing out a module, the ASTWriter stores the names of the files in the main source manager; when loading the AST again, the ASTReader errs out if such a file is found missing, unless it is overridden. Previously CompilerInstance's compileModule method would store the inferred module map to a temporary file; the problem with this approach is that now that the module map is handled by the main source manager, the ASTWriter stores the name of the temporary module map as source to the compilation; later, when the module is loaded, the temporary file has already been deleted, which leads to a compilation error. This patch changes the inferred module map to instead inject a virtual file into the source manager. This both saves some disk IO, and works with how the ASTWriter/ASTReader handle overridden source files. 2. Changing test input in test/Modules/Inputs/* Now that the module map file is handled by the main source manager, the VerifyDiagnosticConsumer will not ignore diagnostics created while parsing the module map file. The module test test/Modules/renamed.m uses -I test/Modules/Inputs and triggers recursive loading of all module maps in test/Modules/Inputs, some of which had conflicting names, thus leading errors while parsing the module maps. Those diagnostics already occur on trunk, but before this patch they would not break the test, as they were ignored by the VerifyDiagnosticConsumer. This patch thus changes the module maps that have been recently introduced which broke the invariant of compatible modules maps in test/Modules/Inputs. llvm-svn: 193314
