2016-04-28[OPENMP] Simplified interface for codegen of tasks, NFC.Alexey Bataev1-12/+3
Reduced number of arguments in member functions of runtime support library for task-based directives. llvm-svn: 267863
2016-04-27[OPENMP] Fix for codegen of captured variables in inlined directives.Alexey Bataev1-0/+5
Currently there is a problem with codegen of inlined directives inside lambdas, it may cause a crash during codegen because of incorrect capturing of variables. Patch fixes this problem. llvm-svn: 267677
2016-04-25[OPENMP 4.5] Codegen for 'taskloop' directive.Alexey Bataev1-0/+20
The taskloop construct specifies that the iterations of one or more associated loops will be executed in parallel using OpenMP tasks. The iterations are distributed across tasks created by the construct and scheduled to be executed. The next code will be generated for the taskloop directive: #pragma omp taskloop num_tasks(N) lastprivate(j) for( i=0; i<N*GRAIN*STRIDE-1; i+=STRIDE ) { int th = omp_get_thread_num(); #pragma omp atomic counter++; #pragma omp atomic th_counter[th]++; j = i; } Generated code: task = __kmpc_omp_task_alloc(NULL,gtid,1,sizeof(struct task),sizeof(struct shar),&task_entry); psh = task->shareds; psh->pth_counter = &th_counter; psh->pcounter = &counter; psh->pj = &j; task->lb = 0; task->ub = N*GRAIN*STRIDE-2; task->st = STRIDE; __kmpc_taskloop( NULL, // location gtid, // gtid task, // task structure 1, // if clause value &task->lb, // lower bound &task->ub, // upper bound STRIDE, // loop increment 0, // 1 if nogroup specified 2, // schedule type: 0-none, 1-grainsize, 2-num_tasks N, // schedule value (ignored for type 0) (void*)&__task_dup_entry // tasks duplication routine ); llvm-svn: 267395
2016-04-22[OPENMP] Fix for LCV in simd directives in explicit clauses.Alexey Bataev1-1/+13
If loop control variable for simd-based directives is explicitly marked as linear/lastprivate in clauses, codegen for such construct would crash. Patch fixes this problem. llvm-svn: 267101
2016-04-08revert SVN r265702, r265640Saleem Abdulrasool1-1/+1
Revert the two changes to thread CodeGenOptions into the TargetInfo allocation and to fix the layering violation by moving CodeGenOptions into Basic. Code Generation is arguably not particularly "basic". This addresses Richard's post-commit review comments. This change purely does the mechanical revert and will be followed up with an alternate approach to thread the desired information into TargetInfo. llvm-svn: 265806
2016-04-07Basic: move CodeGenOptions from FrontendSaleem Abdulrasool1-1/+1
This is a mechanical move of CodeGenOptions from libFrontend to libBasic. This fixes the layering violation introduced earlier by threading CodeGenOptions into TargetInfo. It should also fix the modules based self-hosting builds. NFC. llvm-svn: 265702

2016-03-29[OPENMP] Allow runtime insert its own code inside OpenMP regions.Alexey Bataev1-0/+7
Solution unifies interface of RegionCodeGenTy type to allow insert runtime-specific code before/after main codegen action defined in CGStmtOpenMP.cpp file. Runtime should not define its own RegionCodeGenTy for general OpenMP directives, but must be allowed to insert its own (required) code to support target specific codegen. llvm-svn: 264700

2016-03-21Revert "Convert some ObjC msgSends to runtime calls."Pete Cooper1-6/+2
This reverts commit r263607. This change caused more objc_retain/objc_release calls in the IR but those are then incorrectly optimized by the ARC optimizer. Work is going to have to be done to ensure the ARC optimizer doesn't optimize user written RR, but that should land before this change. This change will also need to be updated to take account for any changes required to ensure that user written calls to RR are distinct from those inserted by ARC. llvm-svn: 263984
2016-03-16Convert some ObjC msgSends to runtime calls.Pete Cooper1-2/+6
It is faster to directly call the ObjC runtime for methods such as retain/release instead of sending a message to those functions. This patch adds support for converting messages to retain/release/alloc/autorelease to their equivalent runtime calls. Tests included for the positive case of applying this transformation, negative tests that we ensure we only convert "alloc" to objc_alloc, not "alloc2", and also a driver test to ensure we enable this only for supported runtime versions.

2016-02-04[PGO] cc1 option name change for profile instrumentationRong Xu1-1/+1
This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level.

2016-01-27Emit calls to objc_unsafeClaimAutoreleasedReturnValue whenJohn McCall1-0/+6
reclaiming a call result in order to ignore it or assign it to an __unsafe_unretained variable. This avoids adding an unwanted retain/release pair when the return value is not actually returned autoreleased (e.g. when it is returned from a nonatomic getter or a typical collection accessor). This runtime function is only available on the latest Apple OS releases; the backwards-compatibility story is that you don't get the optimization unless your deployment target is recent enough.

2015-12-02[OpenMP] Update target directive codegen to use 4.5 implicit data mappings.Samuel Antao1-5/+2
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.
