2014-10-22[modules] Initial support for explicitly loading .pcm files.Richard Smith1-1/+2
Implicit module builds are not well-suited to a lot of build systems. In particular, they fare badly in distributed build systems, and they lead to build artifacts that are not tracked as part of the usual dependency management process. This change allows explicitly-built module files (which are already supported through the -emit-module flag) to be explicitly loaded into a build, allowing build systems to opt to manage module builds and dependencies themselves. This is only the first step in supporting such configurations, and it should be considered experimental and subject to change or removal for now. llvm-svn: 220359
2014-10-15Frontend: Don't accept null DiagnosticsEngines when building ASTUnitsJustin Bogner1-17/+4
The various ways to create an ASTUnit all take a refcounted pointer to a diagnostics engine as an argument, and if it isn't pointing at anything they initialize it. This is a pretty confusing API, and it really makes more sense for the caller to initialize the thing since they control the lifetime anyway. This fixes the one caller that didn't bother initializing the pointer and asserts that the argument is initialized. llvm-svn: 219752
2014-10-14Frontend: Remove some unused arguments in ASTUnit (NFC)Justin Bogner1-5/+4
llvm-svn: 219747
2014-10-03ASTUnit: Replace out parameter with return value, we have NRVO for this.Benjamin Kramer1-22/+22
And elide the copy when pushing the return value into a vector. NFC. llvm-svn: 219001
2014-09-10Unique_ptrify PPCallbacks ownership.Craig Topper1-4/+7
Unique_ptr creation stil needs to be moved earlier at some of the call sites. llvm-svn: 217474
2014-08-29Improve unique_ptr-y ownership in ASTUnit::ComputePreambleDavid Blaikie1-47/+29
Rather than having a pair of pairs and a reference out parameter, build a structure with everything together and named. A raw pointer and a unique_ptr, rather than a raw pointer and a boolean, are used to communicate ownership transfer. It's possible one day we'll end up with a conditional pointer (probably represented by a raw pointer and a boolean) abstraction to use in places like this. Conditional ownership seems to be coming up more often than I'd hoped... llvm-svn: 216712
2014-08-28Don't create a null reference in ASTUnit::LoadFromCommandLine.Alexey Samsonov1-2/+3
This change is the last in the pack of five commits (also see r216691, r216694, r216695, and r216696) that reduces the number of test failures in "check-clang" invocation in UBSan bootstrap from 2443 down to 5. llvm-svn: 216697
2014-08-27Update for LLVM api change.Rafael Espindola1-9/+6

2014-08-18Simplify ASTUnit::Parse a bit by passing a std::unique_ptr to it.Rafael Espindola1-28/+19
llvm-svn: 215900
2014-08-13Small cleanup: Don't duplicate default behavior.Rafael Espindola1-2/+2
std::unique_ptr is null initialized and reset default to null. Thanks to David Blaikie for noticing. llvm-svn: 215560
2014-08-13Use std::unique_ptr to simplify memory management a bit.Rafael Espindola1-12/+6
llvm-svn: 215559
2014-08-12Use StringRef instead of MemoryBuffer&.Rafael Espindola1-2/+2
This code doesn't care where the data it is processing comes from, so a StringRef is probably the most natural interface. llvm-svn: 215448
2014-08-11Change MemoryBuffer* to MemoryBuffer& parameter to Lexer::ComputePreambleDavid Blaikie1-4/+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
2014-08-10Recommit 213307: unique_ptr-ify ownership of ASTConsumers (reverted in r213325)David Blaikie1-15/+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
2014-08-10unique_ptr-ify CompilerInstance::takeSemaDavid Blaikie1-1/+1
llvm-svn: 215321

llvm-svn: 215317
2014-07-17Revert "unique_ptr-ify ownership of ASTConsumers"David Blaikie1-17/+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
2014-07-17unique_ptr-ify ownership of ASTConsumersDavid Blaikie1-15/+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
2014-07-07Remove unused sys/stat.h includesAlp Toker1-1/+0
The facility was abstracted to LLVM in r187364. llvm-svn: 212441
2014-07-07Peel away old-style file remapping typedefs and cruftAlp Toker1-52/+30
llvm-svn: 212438
2014-07-06Use non-intrusive refcounting for TargetOptionsAlp Toker1-21/+18
llvm-svn: 212388
2014-07-06Use non-intrusive refcounting for LangOptionsAlp Toker1-2/+2
This type is only refcounted in a couple of places so making ownership explicit improves clarity. llvm-svn: 212387
2014-07-06Constify a read-only parameter and give function a better nameAlp Toker1-5/+5
This makes it clear that TargetInfo doesn't capture the LangOptions object, rather uses it to apply adjustments. llvm-svn: 212386
2014-07-05Track IntrusiveRefCntPtr::get() changes from LLVM r212366Alp Toker1-7/+7
llvm-svn: 212369
2014-06-30Consider module depedencies when checking a preamble in libclangBen Langmuir1-15/+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
2014-06-23Stop sharing the FileManager in ASTUnit::ParseBen Langmuir1-1/+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
2014-05-22[C++11] Use 'nullptr'. Frontend edition.Craig Topper1-65/+65
llvm-svn: 209389
2014-05-03Eliminate ASTContext's DelayInitialization flagAlp Toker1-8/+3
Having various possible states of initialization following construction doesn't add value here. Also remove the unused size_reserve parameter. llvm-svn: 207897
2014-05-02Reformat code following Preprocessor constructor updatesAlp Toker1-6/+5
Landing this separately to make the previous commits easy to follow at home. llvm-svn: 207826
2014-05-02Factor TargetInfo pointer/DelayInitialization bool pair out of Preprocessor ctorAlp Toker1-3/+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
2014-04-28Remove unused using statement.Nico Weber1-1/+0
llvm-svn: 207427
2014-04-25Push unique_ptr ownership of ASTUnits further back into their factories.David Blaikie1-13/+10
llvm-svn: 207237
2014-04-22Attempt to fix null ASTContext in ASTUnit error pathBen Langmuir1-1/+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
2014-04-18Don't read CompilerInstance fields that don't exist in ASTUnitBen Langmuir1-3/+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
2014-04-15Honour -ivfsoverlay in ASTUnit to match clangBen Langmuir1-8/+27
This allows code indexing, etc. to use the VFS in the same way as the compiler. llvm-svn: 206309

2014-03-09[libclang] Don't pad the main buffer for the preamble.Argyrios Kyrtzidis1-40/+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
2014-03-08[C++11] Replacing EnumDecl iterators enumerator_begin() and enumerator_end() ↵Aaron Ballman1-4/+3
with iterator_range enumerators(). Updating all of the usages of the iterators with range-based for loops. llvm-svn: 203353
2014-03-07Replace OwningPtr with std::unique_ptr.Ahmed Charles1-49/+36
This compiles cleanly with lldb/lld/clang-tools-extra/llvm. llvm-svn: 203279
2014-03-07[C++11] Replacing DeclBase iterators decls_begin() and decls_end() with ↵Aaron Ballman1-3/+2
iterator_range decls(). The same is true for the noload versions of these APIs. Updating all of the usages of the iterators with range-based for loops. llvm-svn: 203278
2014-03-07Change OwningPtr::take() to OwningPtr::release().Ahmed Charles1-5/+6
This is a precursor to moving to std::unique_ptr. llvm-svn: 203275
2014-03-02[C++11] Use std::atomic instead of LLVM's.Benjamin Kramer1-10/+6
No intended functionality change. llvm-svn: 202652

2014-02-27[ASTUnit] Fix use-after-free bug in ↵Argyrios Kyrtzidis1-22/+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
