* Delay emitting members of dllexport classes until the class is fully parsed ↵Hans Wennborg2015-08-154-41/+72
| | | | | | | | | | | | | | | | | (PR23542) This enables Clang to correctly handle code such as: struct __declspec(dllexport) S { int x = 42; }; where it would otherwise error due to trying to generate the default constructor before the in-class initializer for x has been parsed.

| | | | | | | | | | | | | | | Add checkers that detect code-level localizability issues for OS X / iOS: - A path sensitive checker that warns about uses of non-localized NSStrings passed to UI methods expecting localized strings. - A syntax checker that warns against not including a comment in NSLocalizedString macros.

* [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.Alexey Bataev2015-08-145-40/+218
| | | | | | | blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables. We have to rebuild several expression to be sure that all variables are unique. llvm-svn: 245041
* Add structed way to express command line options in the compilation database.Manuel Klimek2015-08-141-27/+42
| | | | | | | | | | | | | | | | | | | | Currently, arguments are passed via the string attribute 'command', assuming a shell-escaped / quoted command line to extract the original arguments. This works well enough on Unix systems, but turns out to be problematic for Windows tools to generate. This CL adds a new attribute 'arguments', an array of strings, which specifies the exact command line arguments. If 'arguments' is available in the compilation database, it is preferred to 'commands'. Currently there is no plan to retire 'commands': there are enough different use cases where users want to create their own mechanism for creating compilation databases, that it doesn't make sense to force them all to implement shell command line parsing. Patch by Daniel Dilts. llvm-svn: 245036

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
* unique_ptrify ConsumedBlockInfo analysis to make it move assignableDavid Blaikie2015-08-141-72/+55
| | | | | | | | | ConsumedBlockInfo objects were move assigned, but only in a state where the dtor was a no-op anyway. Subtle and easily could've happened in ways that wouldn't've been safe - so this change makes it safe no matter what state the ConsumedBlockInfo object is in. llvm-svn: 244998

* Avoid iteration invalidation issues around MaterializedTemporaryExprDavid Majnemer2015-08-132-8/+9
| | | | | | | | | | | | | | | | We risk iterator invalidation issues if we use a DenseMap to hold the backing storage for an APValue. Instead, BumpPtrAllocate them and use APValue * as our DenseMap value. Also, don't assume that MaterializedGlobalTemporaryMap won't regrow between when we initially perform a lookup and later on when we actually try to insert into it. This fixes PR24289.

| | | | | | | | | | | | | files: include the .pcm file itself in the .d output, rather than including its own input files. Other forms of module file continue to be transparent for .d output. Arguably, the input files for the .pcm file are still inputs to the compilation, but that's unnecessary for make-like build systems (where the mtime of the .pcm file is sufficient) and harmful for smarter build systems that know about module files and want to track only the local dependencies. llvm-svn: 244923
* Turn off __has_feature(cxx_rtti) when -fno-rtti-data is presentReid Kleckner2015-08-131-1/+1

* [Modules] Add Darwin-specific compatibility module map parsing hacksBen Langmuir2015-08-132-7/+100
| | | | | | | | | | | | | | | | This preserves backwards compatibility for two hacks in the Darwin system module map files: 1. The use of 'requires excluded' to make headers non-modular, which should really be mapped to 'textual' now that we have this feature. 2. Silently removes a bogus cplusplus requirement from IOKit.avc. Once we start diagnosing missing requirements and headers on auto-imports these would have broken compatibility with existing Darwin SDKs. llvm-svn: 244912

* Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.Ivan Krasin2015-08-134-27/+54
| | | | | | | | | | | | | | | | | | | Summary: Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer, Control Flow Integrity and others, use blacklists to specify which types / functions should not be instrumented to avoid false positives or suppress known failures. This change adds the blacklist filenames to the list of dependencies of the rules, generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain C/C++/ObjC files need to be recompiled (if a blacklist is updated).
