* Allow linking multiple bitcode files.Artem Belevich2015-10-272-57/+69
| | | | | | | | | | | | | | | | | | Linking options for particular file depend on the option that specifies the file. Currently there are two: * -mlink-bitcode-file links in complete content of the specified file. * -mlink-cuda-bitcode links in only the symbols needed by current TU. Linked symbols are internalized. This bitcode linking mode is used to link device-specific bitcode provided by CUDA. Files are linked in order they are specified on command line. -mlink-cuda-bitcode replaces -fcuda-uses-libdevice flag. Differential Revision: http://reviews.llvm.org/D13913 llvm-svn: 251427

* clang-format: Add an additional value to AlignAfterOpenBracket: AlwaysBreak.Daniel Jasper2015-10-274-21/+44
| | | | | | | | | | | | | | | | | | | | Summary: If this option is set, clang-format will always insert a line wrap, e.g. before the first parameter of a function call unless all parameters fit on the same line. This obviates the need to make a decision on the alignment itself. Use this style for Google's JavaScript style and add some minor tweaks to correctly handle nested blocks etc. with it. Don't use this option for for/while loops. Reviewers: klimek Subscribers: klimek, cfe-commits Differential Revision: http://reviews.llvm.org/D14104 llvm-svn: 251405

* [AST] Re-add TypeLocs and NestedNameSpecifierLocs to the ParentMap.Benjamin Kramer2015-10-232-33/+84
| | | | | | | | | | | | | | | | | | | | This relands r250831 after some fixes to shrink the ParentMap overall with one addtional tweak: nodes with pointer identity (e.g. Decl* and friends) can be store more efficiently so I put them in a separate map. All other nodes (so far only TypeLoc and NNSLoc) go in a different map keyed on DynTypedNode. This further uglifies the code but significantly reduces memory overhead. Overall this change still make ParentMap significantly larger but it's nowhere as bad as before. I see about 25 MB over baseline (pre-r251008) on X86ISelLowering.cpp. If this becomes an issue we could consider splitting the maps further as DynTypedNode is still larger (32 bytes) than a single TypeLoc (16 bytes) but I didn't want to introduce even more complexity now.

* Define weak and __weak to mean ARC-style weak references, even in MRC.John McCall2015-10-2220-179/+330
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, __weak was silently accepted and ignored in MRC mode. That makes this a potentially source-breaking change that we have to roll out cautiously. Accordingly, for the time being, actual support for __weak references in MRC is experimental, and the compiler will reject attempts to actually form such references. The intent is to eventually enable the feature by default in all non-GC modes. (It is, of course, incompatible with ObjC GC's interpretation of __weak.) If you like, you can enable this feature with -Xclang -fobjc-weak but like any -Xclang option, this option may be removed at any point, e.g. if/when it is eventually enabled by default. This patch also enables the use of the ARC __unsafe_unretained qualifier in MRC. Unlike __weak, this is being enabled immediately. Since variables are essentially __unsafe_unretained by default in MRC, the only practical uses are (1) communication and (2) changing the default behavior of by-value block capture. As an implementation matter, this means that the ObjC ownership qualifiers may appear in any ObjC language mode, and so this patch removes a number of checks for getLangOpts().ObjCAutoRefCount that were guarding the processing of these qualifiers. I don't expect this to be a significant drain on performance; it may even be faster to just check for these qualifiers directly on a type (since it's probably in a register anyway) than to do N dependent loads to grab the LangOptions. rdar://9674298 llvm-svn: 251041
* [MS ABI] Don't crash when inheriting from base with trailing empty array memberDavid Majnemer2015-10-221-1/+1
| | | | | | | | | | We got this right for Itanium but not MSVC because CGRecordLayoutBuilder was checking if the base's size was zero when it should have been checking the non-virtual size. This fixes PR21040. llvm-svn: 251036

* [Tooling] Add a utility function to replace one nested name with another.Benjamin Kramer2015-10-222-0/+114
| | | | | | | | | | | | | | | | One problem in clang-tidy and other clang tools face is that there is no way to lookup an arbitrary name in the AST, that's buried deep inside Sema and might not even be what the user wants as the new name may be freshly inserted and not available in the AST. A common use case for lookups is replacing one nested name with another while minimizing namespace qualifications, so replacing 'ns::foo' with 'ns::bar' will use just 'bar' if we happen to be inside the namespace 'ns'. This adds a little helper utility for exactly that use case. Differential Revision: http://reviews.llvm.org/D13931 llvm-svn: 251022

* [analyzer] Bug identificationGabor Horvath2015-10-226-10/+262
| | | | | | | | | | | | | | | | This patch adds hashes to the plist and html output to be able to identfy bugs for suppressing false positives or diff results against a baseline. This hash aims to be resilient for code evolution and is usable to identify bugs in two different snapshots of the same software. One missing piece however is a permanent unique identifier of the checker that produces the warning. Once that issue is resolved, the hashes generated are going to change. Until that point this feature is marked experimental, but it is suitable for early adoption. Differential Revision: http://reviews.llvm.org/D10305 Original patch by: Bence Babati! llvm-svn: 251011
* [AST] Remove redundant template keywords.Benjamin Kramer2015-10-221-3/+3
| | | | | | GCC complains about them, clang does not. llvm-svn: 251009
* [AST] Store Decl* and Stmt* directly into the ParentMap.Benjamin Kramer2015-10-221-14/+29
| | | | | | | | | | | | | | | | | | These are by far the most common types to be parents in the AST so it makes sense to optimize for them. Put them directly into the value of the map. This currently saves 32 bytes per parent in the map and a pointer indirection at the cost of some additional complexity in the code. Sadly this means we cannot return an ArrayRef from getParents anymore, add a proxy class that can own a single DynTypedNode and otherwise behaves exactly the same as ArrayRef. For example on a random large file (X86ISelLowering.cpp) this reduces the size of the parent map by 24 MB. Differential Revision: http://reviews.llvm.org/D13976 llvm-svn: 251008
* [MS ABI] Mangle static anonymous unionsDavid Majnemer2015-10-222-13/+4
| | | | | | | | | | | | We believed that internal linkage variables at global scope which are not variable template specializations did not have to be mangled. However, static anonymous unions have no identifier and therefore must be mangled. This fixes PR18204. llvm-svn: 250997
* clang driver toolchain refactoringXinliang David Li2015-10-224-55/+47
| | | | | | | | | | | | | | In this patch, the file static method addProfileRT is moved to be a virtual member function of base ToolChain class. This allows derived toolchain to override the default behavior easily and make it consistent with Darwin toolchain (a TODO was added for this refactoring - now removed). A new helper method is also introduced to test if instrumentation profile option is turned on or not. Differential Revision: http://reviews.llvm.org/D13326 llvm-svn: 250994
