This patch adds OMPD functions defined in 5.5.2 of the OpenMP 5.0 API
documentation. It adds per-process and per-device functions, defines
related handle data types. It also introduces ompd-types.h to Makefile.
2020-07-08 Tony Sim <y2s1...@gmail.com>
libgomp/ChangeLog:
* Makefile.am (libgompd_la_SOURCES): Add ompd-proc.c.
(nodist_libsubinclude_HEADERS): Add ompd-types.h.
* Makefile.in: Regenerate.
* libgompd.h (ompd_address_space_handle_t): Add definition.
* ompd-proc.c: New file.
* ompd-types.h: New file.
