[Patch] libgomp: Add stub omp_control_tool for OMPT
Tobias Burnus <[email protected]>

| Message-ID | <[email protected]> |
This patch adds the omp_control_tool API routine, returning for now alwaysomp_control_tool_notool - it also adds the enum/PARAMETER related to that routine plusomp_pause_stop_tool. I also updated the .texi file for this change. Tobias PS: This will become more useful once OMPT supports lands (which is WIP).

libgomp: Add stub omp_control_tool for OMPT
Add the omp_control_tool (always returning omp_control_tool_notool); add it
and omp_control_tool/omp_control_tool_result enums/parameters to omp.h and
omp_lib.{h,mod}. Plus add OpenMP 6.0's omp_pause_stop_tool named constant.
Note that omp_control_tool uses the OpenMP 6.0 C/C++ prototype that uses an
enum omp_control_tool_t as first argument instead of an 'int'.
gcc/fortran/ChangeLog:
* intrinsic.texi (OpenMP Modules): Add named parameters for
omp_control_tool and omp_control_tool_result.
gcc/ChangeLog:
* omp-general.cc (omp_runtime_api_procname): Add omp_control_tool.
libgomp/ChangeLog:
* env.c (omp_control_tool): Stub implementation for omp_control_tool.
* fortran.c (omp_control_tool_, omp_control_tool_8_): Add.
* libgomp.map (OMP_6.0): Add for omp_control_tool*.
* libgomp.texi (Tool Control Routine): Add for omp_control_tool.
(OpenMP 6.0): Mark omp_pause_stop_tool as implemented.
* omp.h.in (omp_pause_resource_t): Add omp_pause_stop_tool.
(omp_control_tool_result_t): Add.
(omp_control_tool_t): Add.
* omp_lib.f90.in (omp_lib_kinds): Add omp_pause_stop_tool and
omp_control_tool/omp_control_tool_result parameters.
(omp_lib): Add omp_control_tool interface.
* omp_lib.h.in: Add omp_pause_stop_tool and
omp_control_tool/omp_control_tool_result parameters; add
omp_control_tool interface.
* testsuite/libgomp.c/omp-control-tools-1.c: New test.
* testsuite/libgomp.fortran/omp-control-tools-1.f: New test.
* testsuite/libgomp.fortran/omp-control-tools-1.f90: New test.

+@subsection @code{omp_control_tool} -- pass commands to a tool
+@table @asis
+@item @emph{Description}:
+The @code{omp_control_tool} routine can be used to pass commands to a tool. The
+values for @var{modifier} and @var{arg} are specific for the particular tool;
+for Fortran, @var{arg} is NULL. The following predefined values for
+@var{command} are supported by all tools:
+
+@itemize
+@item @code{omp_control_tool_start}: Request that monitoring is started or resumed;
+ it has no effect if monitoring is already on or was turned off permanently.
+@item @code{omp_control_tool_pause}: Request that monitoring is temporarily paused;
+ it has no effect if monitoring is already paused or stopped.
+@item @code{omp_control_tool_flush}: Request flushing of any buffered data,
+ independently whether monitoring is currently active.
+@item @code{omp_control_tool_end}: Request that monitoring is turned off
+ permanently, flushing all output and terminating the tool.
+@end itemize
+
+For the listed standard commands, the @var{modifier} and @var{arg} arguments
+are ignored by the tool.
+
+Negative return values indicate that the tool has not processed the command;
+in particular, the return value is @code{omp_control_tool_notool} if OMPT is
+inactive and no tool is active; if it is active but no callback is registered
+for the tool-control event, @code{omp_control_tool_nocallback} is returned.
+On success, @code{omp_control_tool_success} is returned and
+@code{omp_control_tool_ignored} indicates that the tool received the command
+but ignored it. Positive return values greater than 64 are tool specific.
+
+GCC implements the OpenMP 6.0 version of this function for C and C++, which is
+not compatible with its type signature in previous versions of the OpenMP
+specification. In older versions, the type @code{int} was used for the
+@var{command} argument in place of the enumerated type
+@code{omp_control_tool_t}; the return type likewise changed from @code{int} to
+@code{omp_control_tool_result_t}.

libgomp: Add stub omp_control_tool for OMPT
Add the omp_control_tool (always returning omp_control_tool_notool); add it
and omp_control_tool/omp_control_tool_result enums/parameters to omp.h and
omp_lib.{h,mod}. Plus add OpenMP 6.0's omp_pause_stop_tool named constant.
Note that omp_control_tool uses the OpenMP 6.0 C/C++ prototype that uses an
enum omp_control_tool_t as first argument instead of an 'int'.
gcc/fortran/ChangeLog:
* intrinsic.texi (OpenMP Modules): Add named parameters for
omp_control_tool and omp_control_tool_result.
gcc/ChangeLog:
* omp-general.cc (omp_runtime_api_procname): Add omp_control_tool.
libgomp/ChangeLog:
* env.c (omp_control_tool): Stub implementation for omp_control_tool.
* fortran.c (omp_control_tool_, omp_control_tool_8_): Add.
* libgomp.map (OMP_6.0): Add for omp_control_tool*.
* libgomp.texi (Tool Control Routine): Add for omp_control_tool.
(OpenMP 6.0): Mark omp_pause_stop_tool as implemented.
* omp.h.in (omp_pause_resource_t): Add omp_pause_stop_tool.
(omp_control_tool_result_t): Add.
(omp_control_tool_t): Add.
* omp_lib.f90.in (omp_lib_kinds): Add omp_pause_stop_tool and
omp_control_tool/omp_control_tool_result parameters.
(omp_lib): Add omp_control_tool interface.
* omp_lib.h.in: Add omp_pause_stop_tool and
omp_control_tool/omp_control_tool_result parameters; add
omp_control_tool interface.
* testsuite/libgomp.c/omp-control-tools-1.c: New test.
* testsuite/libgomp.fortran/omp-control-tools-1.f: New test.
* testsuite/libgomp.fortran/omp-control-tools-1.f90: New test.

+@subsection @code{omp_control_tool} -- pass commands to a tool
+@table @asis
+@item @emph{Description}:
+The @code{omp_control_tool} routine can be used to pass commands to a tool. The
+values for @var{modifier} and @var{arg} are specific for the particular tool;
+for Fortran, @var{arg} is NULL. The following predefined values for
+@var{command} are supported by all tools:
+
+@itemize
+@item @code{omp_control_tool_start}: Request that monitoring is started or resumed;
+ it has no effect if monitoring is already on or was turned off permanently.
+@item @code{omp_control_tool_pause}: Request that monitoring is temporarily paused;
+ it has no effect if monitoring is already paused or stopped.
+@item @code{omp_control_tool_flush}: Request flushing of any buffered data,
+ independently whether monitoring is currently active.
+@item @code{omp_control_tool_end}: Request that monitoring is turned off
+ permanently, flushing all output and terminating the tool.
+@end itemize
+
+For the listed standard commands, the @var{modifier} and @var{arg} arguments
+are ignored by the tool.
+
+Negative return values indicate that the tool has not processed the command;
+in particular, the return value is @code{omp_control_tool_notool} if OMPT is
+inactive and no tool is active; if it is active but no callback is registered
+for the tool-control event, @code{omp_control_tool_nocallback} is returned.
+On success, @code{omp_control_tool_success} is returned and
+@code{omp_control_tool_ignored} indicates that the tool received the command
+but ignored it. Positive return values greater than 64 are tool specific.
+
+GCC implements the OpenMP 6.0 version of this function for C and C++, which is
+not compatible with its type signature in previous versions of the OpenMP
+specification. In older versions, the type @code{int} was used for the
+@var{command} argument in place of the enumerated type
+@code{omp_control_tool_t}; the return type likewise changed from @code{int} to
+@code{omp_control_tool_result_t}.
