* [OPENMP]Moved warning fo mapping non-trivially copiable types into aAlexey Bataev2019-12-061-36/+36
| | | | | | | separate group. Need to move this warning into a separate group to make easier to disable this warning, if required.
* 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
| | | | | | | | | This is currently a clang extension and a resolution of the defect report in the C++ Standard. Differential Revision: https://reviews.llvm.org/D46441 llvm-svn: 344150
* [OPENMP] Emit warning for non-trivial types in map clauses.Alexey Bataev2018-02-271-36/+36
| | | | | | | If the mapped type is non-trivial, the warning message is emitted for better user experience. llvm-svn: 326251
* Change memcpy/memove/memset to have dest and source alignment attributes ↵Daniel Neilson2018-01-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | (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/+24
| | | | | | | | | only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560
* [OpenMP] Use fopenmp prefix for all options introduced by the offloading ↵Samuel Antao2016-06-301-18/+18
| | | | | | | | | | | | | | implementation. Summary: This patch changes the options used by offloading to start with -fopenmp instead of -fomp. This makes the option naming more consistent and materializes a suggestion by Richard Smith in http://reviews.llvm.org/D9888.

* [OpenMP] Cast captures by copy when passed to fork call so that they are ↵Samuel Antao2016-06-161-7/+13
| | | | | | | | | | | | | | | | | compatible to what the runtime library expects. Summary: This patch fixes an issue detected when firstprivate variables are passed to an OpenMP outlined function vararg list. Currently they are not compatible with what the runtime library expects causing malfunction in some targets. This patch fixes the issue by moving the casting logic already in place for offloading to the common code that creates the outline function and arguments and updates the regression tests accordingly.

* [OPENMP] Pass scalar firstprivate vars by value.Alexey Bataev2016-05-171-35/+23
| | | | | | | | For better performance and to unify code with offloading part we pass scalar firstprivate values by value, instead of by reference. It will remove some extra copying operations. llvm-svn: 269751
* [OpenMP] Replace offloading option that start with -o with -fo.Samuel Antao2016-03-141-18/+18
| | | | | | | | | | | | | | | Summary: The current offloading implementation is using -omptargets and -omp-host-ir-file-path options in the frontend. This causes the user a lot of trouble due to to the conflicts with the -o option. E.g. if the user misspells omptargets he will end up with a file with a weird name. This patches replaces these two options with -fomptargets and -fomp-host-ir-file-path to avoid these issues, and it is also more consistent with the other options like -fopenmp.

* [OPENMP] firstprivate and private clauses of teams, host codegenerationCarlo Bertolli2016-03-031-0/+289
Add code generation support for firstprivate and private clauses of teams on the host. Add extensive regression tests including lambda functions and vla testing. http://reviews.llvm.org/D17582 llvm-svn: 262663
