Joachim Protze	e2f5444c9c	[OpenMP][Tests] Enable nvptx64 testing for most libomptarget tests ... Also add $BUILD/lib to the LIBRARY_PATH to fix https://bugs.llvm.org/show_bug.cgi?id=46836. Reviewed By: JonChesterfield Differential Revision: https://reviews.llvm.org/D84557	2020-07-28 11:08:24 +02:00
Gheorghe-Teodor Bercea	a1d20506e7	[OpenMP][libomptarget] Add support for unified memory for regular maps ... Summary: This patch adds support for using unified memory in the case of regular maps that happen when a target region is offloaded to the device. For cases where only a single version of the data is required then the host address can be used. When variables need to be privatized in any way or globalized, then the copy to the device is still required for correctness.

Gheorghe-Teodor Bercea	9e9c918259	[OpenMP][libomptarget] Enable requires flags for target libraries. ... Summary: Target link variables are currently implemented by creating a copy of the variables on the device side and unified memory never gets exploited. When the prgram uses the: ``` #pragma omp requires unified_shared_memory ``` directive in conjunction with a declare target link, the linked variable is no longer allocated on the device and the host version is used instead. This behavior is overridden by performing an explicit mapping. A Clang side patch is required.
