* [MSVC] 'property' with an empty array in array subscript expression.Alexey Bataev2015-11-252-0/+18
| | | | | | | | | | | | MSVC supports 'property' attribute and allows to apply it to the declaration of an empty array in a class or structure definition. For example: ``` __declspec(property(get=GetX, put=PutX)) int x[]; ``` The above statement indicates that x[] can be used with one or more array indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i); Differential Revision: http://reviews.llvm.org/D13336 llvm-svn: 254067

* Add support for GCC's '__auto_type' extension, per the GCC manual:Richard Smith2015-11-112-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | https://gcc.gnu.org/onlinedocs/gcc/Typeof.html Differences from the GCC extension: * __auto_type is also permitted in C++ (but only in places where it could appear in C), allowing its use in headers that might be shared across C and C++, or used from C++98 * __auto_type can be combined with a declarator, as with C++ auto (for instance, "__auto_type *p") * multiple variables can be declared in a single __auto_type declaration, with the C++ semantics (the deduced type must be the same in each case) This patch also adds a missing restriction on applying typeof to a bit-field, which GCC has historically rejected in C (due to lack of clarity as to whether the operand should be promoted). The same restriction also applies to __auto_type in C (in both GCC and Clang). This also fixes PR25449. Patch by Nicholas Allegra! llvm-svn: 252690

| | | | | | | | | we can't load that file due to a configuration mismatch, and implicit module building is disabled, and the user turns off the error-by-default warning for that situation, then fall back to textual inclusion for the module rather than giving an error if any of its headers are included. llvm-svn: 252114
* [Sema] Implement __make_integer_seqDavid Majnemer2015-11-044-0/+11
| | | | | | | | | | | | | | | | | | This new builtin template allows for incredibly fast instantiations of templates like std::integer_sequence. Performance numbers follow: My work station has 64 GB of ram + 20 Xeon Cores at 2.8 GHz. __make_integer_seq<std::integer_sequence, int, 90000> takes 0.25 seconds. std::make_integer_sequence<int, 90000> takes unbound time, it is still running. Clang is consuming gigabytes of memory. Differential Revision: http://reviews.llvm.org/D13786 llvm-svn: 252036
* Introduce module file extensions to piggy-back data onto module files.Douglas Gregor2015-11-035-50/+273
| | | | | | | | | | | | | | | | | | | | | Introduce the notion of a module file extension, which introduces additional information into a module file at the time it is built that can then be queried when the module file is read. Module file extensions are identified by a block name (which must be unique to the extension) and can write any bitstream records into their own extension block within the module file. When a module file is loaded, any extension blocks are matched up with module file extension readers, that are per-module-file and are given access to the input bitstream. Note that module file extensions can only be introduced by programmatic clients that have access to the CompilerInvocation. There is only one such extension at the moment, which is used for testing the module file extension harness. As a future direction, one could imagine allowing the plugin mechanism to introduce new module file extensions. llvm-svn: 251955
* Eliminate "rewritten decls" from the AST writer. NFCDouglas Gregor2015-11-032-23/+10

* Stop back-patching 'readonly' Objective-C properties with 'readwrite' ones.Douglas Gregor2015-11-031-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A 'readonly' Objective-C property declared in the primary class can effectively be shadowed by a 'readwrite' property declared within an extension of that class, so long as the types and attributes of the two property declarations are compatible. Previously, this functionality was implemented by back-patching the original 'readonly' property to make it 'readwrite', destroying source information and causing some hideously redundant, incorrect code. Simplify the implementation to express how this should actually be modeled: as a separate property declaration in the extension that shadows (via the name lookup rules) the declaration in the primary class. While here, correct some broken Fix-Its, eliminate a pile of redundant code, clean up the ARC migrator's handling of properties declared in extensions, and fix debug info's naming of methods that come from categories. A wonderous side effect of doing this write is that it eliminates the "AddedObjCPropertyInClassExtension" method from the AST mutation listener, which in turn eliminates the last place where we rewrite entire declarations in a chained PCH file or a module file. This change (which fixes rdar://problem/18475765) will allow us to eliminate the rewritten-decls logic from the serialization library, and fixes a crash (rdar://problem/23247794) illustrated by the test/PCH/chain-categories.m example. llvm-svn: 251874
* Fix missing builtin identifier infos with PCH+modulesBen Langmuir2015-10-281-2/+4
| | | | | | | | | | | | | | Use the *current* state of "is-moduleness" rather than the state at serialization time so that if we read a builtin identifier from a module that wasn't "interesting" to that module, we will still write it out to a PCH that imports that module. Otherwise, we would get mysterious "unknown builtin" errors when using PCH+modules. rdar://problem/23287656 llvm-svn: 251565

* Fix use-after-free in ModuleManagerBen Langmuir2015-10-211-0/+3
| | | | | | | | | | | | | When removing out-of-date modules we might have left behind a VisitOrder that contains pointers to freed ModuleFiles. This was very rarely seen, because it only happens when modules go out of date and the VisitOrder happens to have the right size to not be recomputed. Thanks ASan! rdar://23181512 llvm-svn: 250963

* [modules] Fix merging of __va_list_tag's implicit special member functions.Richard Smith2015-10-131-6/+31
| | | | | | | | | | | We model predefined declarations as not being from AST files, but in most ways they act as if they come from some implicit prebuilt module file imported before all others. Therefore, if we see an update to the predefined 'struct __va_list_tag' declaration (and we've already loaded any modules), it needs a corresponding update record, even though it didn't technically come from an AST file. llvm-svn: 250134

* [OPENMP 4.1] Add 'simd' clause for 'ordered' directive.Alexey Bataev2015-09-282-0/+7
| | | | | | | | | | | Parsing and sema analysis for 'simd' clause in 'ordered' directive. Description If the simd clause is specified, the ordered regions encountered by any thread will use only a single SIMD lane to execute the ordered regions in the order of the loop iterations. Restrictions An ordered construct with the simd clause is the only OpenMP construct that can appear in the simd region llvm-svn: 248696

* [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.Alexey Bataev2015-09-252-1/+12
| | | | | | | | OpenMP 4.1 extends format of '#pragma omp ordered'. It adds 3 additional clauses: 'threads', 'simd' and 'depend'. If no clause is specified, the ordered construct behaves as if the threads clause had been specified. If the threads clause is specified, the threads in the team executing the loop region execute ordered regions sequentially in the order of the loop iterations. The loop region to which an ordered region without any clause or with a threads clause binds must have an ordered clause without the parameter specified on the corresponding loop directive. llvm-svn: 248569

* Module Debugging: Use the clang module signature as the module's dwo_idAdrian Prantl2015-09-221-1/+2
| | | | | | | | | | | when building a module. Clang already records the module signature when building a skeleton CU to reference a clang module. Matching the id in the skeleton with the one in the module allows a DWARF consumer to verify that they found the correct version of the module without them needing to know about the clang module format. llvm-svn: 248345

| | | | | | | | | | | | | | | | | | Summary: This change adds support for `__builtin_ms_va_list`, a GCC extension for variadic `ms_abi` functions. The existing `__builtin_va_list` support is inadequate for this because `va_list` is defined differently in the Win64 ABI vs. the System V/AMD64 ABI. Depends on D1622.

| | | | | | | | | | | | | | if 'cancel' is found. Patch improves codegen for OpenMP constructs. If the OpenMP region does not have internal 'cancel' construct, a call to 'void __kmpc_barrier()' runtime function is generated for all implicit/explicit barriers. If the region has inner 'cancel' directive, then ``` if (__kmpc_cancel_barrier()) exit from outer construct; ``` code is generated. Also, the code for 'canellation point' directive is not generated if parent directive does not have 'cancel' directive. llvm-svn: 247681
