gcc/
* doc/install.texi: Remove entry about --with-hsa-kmt-lib.
libgomp/
* plugin/hsa.h: New file.
* plugin/hsa_ext_finalize.h: New file.
* plugin/configfrag.ac: Remove hsa-kmt-lib test. Added checks for
header file unistd.h, and functions secure_getenv, __secure_getenv,
getuid, geteuid, getgid and getegid.
* plugin/Makefrag.am (libgomp_plugin_hsa_la_CPPFLAGS): Added
-D_GNU_SOURCE.
* plugin/plugin-hsa.c: Include config.h, inttypes.h and stdbool.h.
Handle various cases of secure_getenv presence, add an implementation
when we can test effective UID and GID.
(struct hsa_runtime_fn_info): New structure.
(hsa_runtime_fn_info hsa_fns): New variable.
(hsa_runtime_lib): Likewise.
(support_cpu_devices): Likewise.
(init_enviroment_variables): Load newly introduced ENV
variables.
(hsa_warn): Call hsa run-time functions via hsa_fns structure.
(hsa_fatal): Likewise.
(DLSYM_FN): New macro.
(init_hsa_runtime_functions): New function.
(suitable_hsa_agent_p): Call hsa run-time functions via hsa_fns
structure. Depending on environment, also allow CPU devices.
(init_hsa_context): Call hsa run-time functions via hsa_fns structure.
(get_kernarg_memory_region): Likewise.
(GOMP_OFFLOAD_init_device): Likewise.
(destroy_hsa_program): Likewise.
(init_basic_kernel_info): New function.

(GOMP_OFFLOAD_run): Outline most functionality to run_kernel.
(GOMP_OFFLOAD_fini_device): Call hsa run-time functions via hsa_fns
structure.
* testsuite/lib/libgomp.exp: Remove hsa_kmt_lib support.
* testsuite/libgomp-test-support.exp.in: Likewise.
* Makefile.in: Regenerated.
