* [OPENMP]Moved warning fo mapping non-trivially copiable types into aAlexey Bataev2019-12-061-16/+16
| | | | | | | separate group. Need to move this warning into a separate group to make easier to disable this warning, if required.
* [OPENMP]Simplify codegen for the outlined regions.Alexey Bataev2019-05-231-10/+10
| | | | | | | Simplified codegen for the outlined regions, excluding duplication code for handling variables with the reference types. llvm-svn: 361529

Compiler did not generate error reports for the variables used in other OpenMP regions. Patch fixes this. llvm-svn: 345533
* Revert "[CodeGenCXX] Treat 'this' as noalias in constructors"Sean Fertile2018-10-151-8/+8
| | | | | | | This reverts commit https://reviews.llvm.org/rL344150 which causes MachineOutliner related failures on the ppc64le multistage buildbot. llvm-svn: 344526
* [CodeGenCXX] Treat 'this' as noalias in constructorsAnton Bikineev2018-10-101-8/+8

* Change memcpy/memove/memset to have dest and source alignment attributes ↵Daniel Neilson2018-01-191-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | (Step 1). Summary: Upstream LLVM is changing the the prototypes of the @llvm.memcpy/memmove/memset intrinsics. This change updates the Clang tests for this change. The @llvm.memcpy/memmove/memset intrinsics currently have an explicit argument which is required to be a constant integer. It represents the alignment of the dest (and source), and so must be the minimum of the actual alignment of the two. This change removes the alignment argument in favour of placing the alignment attribute on the source and destination pointers of the memory intrinsic call. For example, code which used to read: call void @llvm.memcpy.p0i8.p0i8.i32(i8* %dest, i8* %src, i32 100, i32 4, i1 false) will now read call void @llvm.memcpy.p0i8.p0i8.i32(i8* align 4 %dest, i8* align 4 %src, i32 100, i1 false) At this time the source and destination alignments must be the same (Step 1). Step 2 of the change, to be landed shortly, will relax that contraint and allow the source and destination to have different alignments. llvm-svn: 322964
* [OPENMP] Support for -fopenmp-simd option with compilation of simd loopsAlexey Bataev2017-12-291-0/+16
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560
* [OPENMP] Simplify codegen for loop iteration variables in loop preamble.Alexey Bataev2017-12-081-1/+1
| | | | | | | Initial patch could cause trouble in the optimized code because of the incorrectly generated lifetime intrinsics. llvm-svn: 320191
* [OPENMP] Fix PR35486: crash when collapsing loops with dependent iteration ↵Alexey Bataev2017-12-041-0/+6
| | | | | | | | | | spaces. Though it is incorrect from point of view of OpenMP standard to have dependent iteration space in OpenMP loops, compiler should not crash. Patch fixes this problem. llvm-svn: 319700

| | | | | | | | | | | | | | [OpenMP] Initial implementation of code generation for pragma 'distribute parallel for' on host https://reviews.llvm.org/D29508 This patch makes the following additions: It abstracts away loop bound generation code from procedures associated with pragma 'for' and loops in general, in such a way that the same procedures can be used for 'distribute parallel for' without the need for a full re-implementation. It implements code generation for 'distribute parallel for' and adds regression tests. It includes tests for clauses. It is important to notice that most of the clauses are implemented as part of existing procedures. For instance, firstprivate is already implemented for 'distribute' and 'for' as separate pragmas. As the implementation of 'distribute parallel for' is based on the same procedures, then we automatically obtain implementation for such clauses without the need to add new code. However, this requires regression tests that verify correctness of produced code. llvm-svn: 301340

It abstracts away loop bound generation code from procedures associated with pragma 'for' and loops in general, in such a way that the same procedures can be used for 'distribute parallel for' without the need for a full re-implementation. 2. It implements code generation for 'distribute parallel for' and adds regression tests. It includes tests for clauses.

However, this requires regression tests that verify correctness of produced code. Looking forward to comments. llvm-svn: 301223
