* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-091-5/+5
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* [ObjC] Warn on unguarded use of partial declarationErik Pilkington2016-08-161-0/+4
| | | | | | | | | | | | | | This commit adds a traversal of the AST after Sema of a function that diagnoses unguarded references to declarations that are partially available (based on availability attributes). This traversal is only done when we would otherwise emit -Wpartial-availability.

| | | | | | | | | | | | | | | keys, and PointerIntPairs where the pointee types are incomplete out-of-line to where we have the complete type. This is the standard pattern used throughout the AST library to address the inherently mutually cross referenced nature of the AST. This is part of a series of patches to allow LLVM to check for complete pointee types when computing its pointer traits. This is absolutely necessary to get correct (or reproducible) results for things like how many low bits are guaranteed to be zero. llvm-svn: 256612

* [OpenMP] Update target directive codegen to use 4.5 implicit data mappings.Samuel Antao2015-12-021-0/+27
| | | | | | | | | | | | | | | Summary: This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed. Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.

* Move functions declared in Stmt{ObjC,CXX}.h and OpenMPClause.h intoJames Y Knight2015-10-021-1258/+0
| | | | | | | | | | | their associated .cpp file. Previous refactorings long long ago had split out the above categories of classes from Stmt.h into their own header files, but failed to also split the Stmt.cpp implementation file similarly. Do so for readability's sake. llvm-svn: 249131
* [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.Alexey Bataev2015-09-251-6/+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
* [OPENMP 4.0] Add 'if' clause for 'cancel' directive.Alexey Bataev2015-09-181-6/+11
| | | | | | Add parsing, sema analysis and codegen for 'if' clause in 'cancel' directive. llvm-svn: 247976
* [OPENMP] Emit __kmpc_cancel_barrier() and code for 'cancellation point' only ↵Alexey Bataev2015-09-151-15/+19
| | | | | | | | | | | | | | 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
* [OpenMP] Make the filetered clause iterator a real iterator and type safe.Benjamin Kramer2015-08-301-12/+0
| | | | | | | | | This replaces the filtered generic iterator with a type-specfic one based on dyn_cast instead of comparing the kind enum. This allows us to use range-based for loops and eliminates casts. No functionality change intended. llvm-svn: 246384
* [OPENMP 4.0] Initial support for array sections.Alexey Bataev2015-08-251-0/+1
| | | | | | | | Adds parsing/sema analysis/serialization/deserialization for array sections in OpenMP constructs (introduced in OpenMP 4.0). Currently it is allowed to use array sections only in OpenMP clauses that accepts list of expressions. Differential Revision: http://reviews.llvm.org/D10732 llvm-svn: 245937
* [OPENMP 4.1] Initial support for modifiers in 'linear' clause.Alexey Bataev2015-08-201-2/+3
| | | | | | | | | | | | | | | | | | | | | | OpenMP 4.1 adds 3 optional modifiers to 'linear' clause. Format of 'linear' clause has changed to: ``` linear(linear-list[ : linear-step]) ``` where linear-list is one of the following ``` list modifier(list) ``` where modifier is one of the following: ``` ref (C++) val (C/C++) uval (C++) ``` Patch adds parsing and sema analysis for these modifiers. llvm-svn: 245550
* [OPENMP 4.1] Allow variables with reference types in private clauses.Alexey Bataev2015-08-181-8/+14
| | | | | | OpenMP 4.1 allows to use variables with reference types in all private clauses (private, firstprivate, lastprivate, linear etc.). Patch allows to use such variables and fixes codegen for linear variables with reference types. llvm-svn: 245268
* [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.Alexey Bataev2015-08-141-0/+11
| | | | | | | 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
* [OPENMP 4.1] Allow references in init expression for loop-based constructs.Alexey Bataev2015-08-061-0/+12
| | | | | | OpenMP 4.1 allows to use variables with reference types in private clauses and, therefore, in init expressions of the cannonical loop forms. llvm-svn: 244209
* [ASTContext] Add a templated convenience wrapper for Allocate.Benjamin Kramer2015-08-041-1/+1
| | | | | | | | | This brings ASTContext closer to LLVM's Allocator concept. Ideally we would just derive ASTContext from llvm::AllocatorBase, but that does not work because ASTContext's allocator is mutable and we allocate using const ASTContext& everywhere. llvm-svn: 243972

* [UB] When attaching empty strings to the AST, use an empty StringRefChandler Carruth2015-08-041-0/+2
| | | | | | | | rather than forcing the bump pointer allocator to produce a viable pointer. This also fixes UB when we would try to memcpy from the null incoming StringRef. llvm-svn: 243947

* [AST] Remove StmtRange in favor of an iterator_range.Benjamin Kramer2015-07-181-1/+1
| | | | | | | | | StmtRange was just a convenient wrapper for two StmtIterators before we had real range support. This removes some of the implicit conversions StmtRange had leading to slightly more verbose code but also should make more obvious what's going on. No functional change intended. llvm-svn: 242615
* Fix alignment issues in Clang.James Y Knight2015-07-171-3/+2
| | | | | | | | | | | | | | | | | Some const-correctness changes snuck in here too, since they were in the area of code I was modifying. This seems to make Clang actually work without Bus Error on 32bit-sparc. Follow-up patches will factor out a trailing-object helper class, to make classes using the idiom of appending objects to other objects easier to understand, and to ensure (with static_assert) that required alignment guarantees continue to hold.

* [OPENMP] Support for '#pragma omp taskgroup' directive.Alexey Bataev2015-06-181-1/+22
| | | | | | | | | | | | | Added parsing, sema analysis and codegen for '#pragma omp taskgroup' directive (OpenMP 4.0). The code for directive is generated the following way: #pragma omp taskgroup <body> void __kmpc_taskgroup(<loc>, thread_id); <body> void __kmpc_end_taskgroup(<loc>, thread_id); llvm-svn: 240011
* [OPENMP] Remove last iteration separation for loop-based constructs.Alexey Bataev2015-06-161-5/+5
| | | | | | Previously the last iteration for simd loop-based OpenMP constructs were generated as a separate code. This feature is not required and codegen is simplified. llvm-svn: 239810
