Add two new compiler flags, -fopenmp-ompt and -fopenmp-ompt-detailed, that
cause the compiler to emit OMPT-aware runtime entry points around OpenMP
worksharing constructs. With -fopenmp-ompt, the _start and _end variants
are called instead of the plain worksharing functions; with
-fopenmp-ompt-detailed, a _dispatch stub is additionally called after the
chunk bounds are computed. New stubs are added to libgomp as placeholders
for future OMPT callback invocations.
gcc/ChangeLog:
* common.opt (fopenmp-ompt): New option.
(fopenmp-ompt-detailed): New option.
* omp-builtins.def (BUILT_IN_GOMP_SINGLE_START_WITH_END): New builtin.
(BUILT_IN_GOMP_SINGLE_END): New builtin.
(BUILT_IN_GOMP_MASKED_END): New builtin.
(BUILT_IN_GOMP_LOOP_STATIC_WORKSHARING_START): New builtin.
(BUILT_IN_GOMP_LOOP_STATIC_WORKSHARING_END): New builtin.
(BUILT_IN_GOMP_LOOP_STATIC_WORKSHARING_DISPATCH): New builtin.
(BUILT_IN_GOMP_DISTRIBUTE_STATIC_WORKSHARING_START): New builtin.
(BUILT_IN_GOMP_DISTRIBUTE_STATIC_WORKSHARING_END): New builtin.
(BUILT_IN_GOMP_DISTRIBUTE_STATIC_WORKSHARING_DISPATCH): New builtin.
* omp-expand.cc (expand_omp_for_static_nochunk): With -fopenmp-ompt,
emit _start and _end variants instead of the plain worksharing call;
with -fopenmp-ompt-detailed, also emit _dispatch.
(expand_omp_for_static_chunk): Likewise.
* omp-low.cc (lower_omp_single_simple): With -fopenmp-ompt, use
GOMP_single_start_with_end instead of GOMP_single_start.
(lower_omp_single): With -fopenmp-ompt, emit GOMP_single_end.
(lower_omp_master): With -fopenmp-ompt, emit GOMP_masked_end.
* opts.cc (finish_options): Diagnose -fopenmp-ompt and
-fopenmp-ompt-detailed used without -fopenmp.
libgomp/ChangeLog:
* libgomp.map (GOMP_6.0.2): Export new entry points.
* loop.c (GOMP_loop_static_worksharing): Move here from parallel.c.
(GOMP_loop_static_worksharing_start): New function.
(GOMP_loop_static_worksharing_dispatch): New stub.
(GOMP_loop_static_worksharing_end): New stub.
(GOMP_has_masked_thread_num): Move here from parallel.c.
(GOMP_masked_end): New stub.
* parallel.c (GOMP_loop_static_worksharing): Move to loop.c.
(GOMP_has_masked_thread_num): Move to loop.c.
* single.c (GOMP_single_start_with_end): New function.
(GOMP_single_end): New stub.
(GOMP_single_copy_start): Fix trailing whitespace.
* teams.c (GOMP_distribute_static_worksharing_start): New function.
(GOMP_distribute_static_worksharing_dispatch): New stub.
(GOMP_distribute_static_worksharing_end): New stub.
gcc/testsuite/ChangeLog:
* c-c++-common/gomp/masked-1.c: Add scan-tree-dump-not check that
GOMP_masked_end is not emitted without -fopenmp-ompt.
* c-c++-common/gomp/for-8.c: Remove; superseded by for-static-*.c.
* c-c++-common/gomp/for-static-1.c: New test; checks that the plain
worksharing builtins are emitted without -fopenmp-ompt.
* c-c++-common/gomp/for-static-2.c: New test; checks that _start and
_end variants are emitted with -fopenmp-ompt.
* c-c++-common/gomp/for-static-3.c: New test; checks that _dispatch is
also emitted with -fopenmp-ompt-detailed.
* c-c++-common/gomp/for-static.h: New shared test header.
* c-c++-common/gomp/masked-3.c: New test for GOMP_masked_end emission
with -fopenmp-ompt.
* c-c++-common/gomp/openmp-ompt-1.c: New test; checks that
-fopenmp-ompt without -fopenmp is diagnosed.
* c-c++-common/gomp/openmp-ompt-2.c: New test; checks that
-fopenmp-ompt-detailed without -fopenmp is diagnosed.
* c-c++-common/gomp/single2.c: New test for GOMP_single_start_with_end
and GOMP_single_end emission with -fopenmp-ompt.
