-Notes on the external ABI presented by libgomp. This ought to get
-transformed into proper documentation at some point.
-
-Implementing MASTER construct
-
- if (omp_get_thread_num () == 0)
- block
-
- Alternately, we generate two copies of the parallel subfunction
- and only include this in the version run by the master thread.
- Surely that's not worthwhile though...
-
-Implementing CRITICAL construct
-
- Without a specified name,
-
- void GOMP_critical_start (void);
- void GOMP_critical_end (void);
-
- so that we don't get COPY relocations from libgomp to the main
- application.
-
- With a specified name, use omp_set_lock and omp_unset_lock with
- name being transformed into a variable declared like
-
- omp_lock_t gomp_critical_user_<name>
- __attribute__((common))
-
- Ideally the ABI would specify that all zero is a valid unlocked
- state, and so we wouldn't actually need to initialize this at
- startup.
-
-Implementing ATOMIC construct
-
- The target should implement the __sync builtins.
-
- Failing that we could add
-
- void GOMP_atomic_enter (void)
- void GOMP_atomic_exit (void)
-
- which reuses the regular lock code, but with yet another lock
- object private to the library.
-
-Implementing FLUSH construct
-
- Expands to the __sync_synchronize builtin.
-
-Implementing BARRIER construct
-
- void GOMP_barrier (void)
-
-Implementing THREADPRIVATE construct
-
- In _most_ cases we can map this directly to __thread. Except
- that OMP allows constructors for C++ objects. We can either
- refuse to support this (how often is it used?) or we can
- implement something akin to .ctors.
-
- Even more ideally, this ctor feature is handled by extensions
- to the main pthreads library. Failing that, we can have a set
- of entry points to register ctor functions to be called.
-
-Implementing PRIVATE clause
-
- In association with a PARALLEL, or within the lexical extent
- of a PARALLEL block, the variable becomes a local variable in
- the parallel subfunction.
-
- In association with FOR or SECTIONS blocks, create a new
- automatic variable within the current function. This preserves
- the semantic of new variable creation.
-
-Implementing FIRSTPRIVATE, LASTPRIVATE, COPYIN, COPYPRIVATE clauses
-
- Seems simple enough for PARALLEL blocks. Create a private
- struct for communicating between parent and subfunction.
- In the parent, copy in values for scalar and "small" structs;
- copy in addresses for others TREE_ADDRESSABLE types. In the
- subfunction, copy the value into the local variable.
-
- Not clear at all what to do with bare FOR or SECTION blocks.
- The only thing I can figure is that we do something like
-
-
- #pragma omp for firstprivate(x) lastprivate(y)
- for (int i = 0; i < n; ++i)
- body;
-
- =>
-
- {
- int x = x, y;
-
- // for stuff
-
- if (i == n)
- y = y;
- }
-
- where the "x=x" and "y=y" assignments actually have different
- uids for the two variables, i.e. not something you could write
- directly in C. Presumably this only makes sense if the "outer"
- x and y are global variables.
-
- COPYPRIVATE would work the same way, except the structure
- broadcast would have to happen via SINGLE machinery instead.
-
-Implementing REDUCTION clause
-
- The private struct mentioned above should have a pointer to
- an array of the type of the variable, indexed by the thread's
- team_id. The thread stores its final value into the array,
- and after the barrier the master thread iterates over the
- array to collect the values.
-
-Implementing PARALLEL construct
-
- #pragma omp parallel
- {
- body;
- }
-
- =>
-
- void subfunction (void *data)
- {
- use data;
- body;
- }
-
- setup data;
- GOMP_parallel_start (subfunction, &data, num_threads);
- subfunction (&data);
- GOMP_parallel_end ();
-
- void GOMP_parallel_start (void (*fn)(void *), void *data,
- unsigned num_threads)
-
- The FN argument is the subfunction to be run in parallel.
-
- The DATA argument is a pointer to a structure used to
- communicate data in and out of the subfunction, as discussed
- above wrt FIRSTPRIVATE et al.
-
- The NUM_THREADS argument is 1 if an IF clause is present
- and false, or the value of the NUM_THREADS clause, if
- present, or 0.
-
- The function needs to create the appropriate number of
- threads and/or launch them from the dock. It needs to
- create the team structure and assign team ids.
-
- void GOMP_parallel_end (void)
-
- Tears down the team and return us to the previous
- omp_in_parallel() state.
-
-Implementing FOR construct
-
- #pragma omp parallel for
- for (i = lb; i <= ub; i++)
- body;
-
- =>
-
- void subfunction (void *data)
- {
- long _s0, _e0;
- while (GOMP_loop_static_next (&_s0, &_e0))
- {
- long _e1 = _e0, i;
- for (i = _s0; i < _e1; i++)
- body;
- }
- GOMP_loop_end_nowait ();
- }
-
- GOMP_parallel_loop_static (subfunction, NULL, 0, lb, ub+1, 1, 0);
- subfunction (NULL);
- GOMP_parallel_end ();
-
- #pragma omp for schedule(runtime)
- for (i = 0; i < n; i++)
- body;
-
- =>
-
- {
- long i, _s0, _e0;
- if (GOMP_loop_runtime_start (0, n, 1, &_s0, &_e0))
- do {
- long _e1 = _e0;
- for (i = _s0, i < _e0; i++)
- body;
- } while (GOMP_loop_runtime_next (&_s0, _&e0));
- GOMP_loop_end ();
- }
-
- Note that while it looks like there is trickyness to propagating
- a non-constant STEP, there isn't really. We're explicitly allowed
- to evaluate it as many times as we want, and any variables involved
- should automatically be handled as PRIVATE or SHARED like any other
- variables. So the expression should remain evaluable in the
- subfunction. We can also pull it into a local variable if we like,
- but since its supposed to remain unchanged, we can also not if we like.
-
- If we have SCHEDULE(STATIC), and no ORDERED, then we ought to be
- able to get away with no work-sharing context at all, since we can
- simply perform the arithmetic directly in each thread to divide up
- the iterations. Which would mean that we wouldn't need to call any
- of these routines.
-
- There are separate routines for handling loops with an ORDERED
- clause. Bookkeeping for that is non-trivial...
-
-Implementing ORDERED construct
-
- void GOMP_ordered_start (void)
- void GOMP_ordered_end (void)
-
-Implementing SECTIONS construct
-
- #pragma omp sections
- {
- #pragma omp section
- stmt1;
- #pragma omp section
- stmt2;
- #pragma omp section
- stmt3;
- }
-
- =>
-
- for (i = GOMP_sections_start (3); i != 0; i = GOMP_sections_next ())
- switch (i)
- {
- case 1:
- stmt1;
- break;
- case 2:
- stmt2;
- break;
- case 3:
- stmt3;
- break;
- }
- GOMP_barrier ();
-
-Implementing SINGLE construct
-
- #pragma omp single
- {
- body;
- }
-
- =>
-
- if (GOMP_single_start ())
- body;
- GOMP_barrier ();
-
-
- #pragma omp single copyprivate(x)
- body;
-
- =>
-
- datap = GOMP_single_copy_start ();
- if (datap == NULL)
- {
- body;
- data.x = x;
- GOMP_single_copy_end (&data);
- }
- else
- x = datap->x;
- GOMP_barrier ();

+@chapter Enabling OpenMP
+
+To activate the OpenMP extensions for C/C++ and Fortran, the compile-time
+flag @command{-fopenmp} must be specified. This enables the OpenMP directive
+@code{#pragma omp} in C/C++ and @code{!$omp} directives in free form,
+@code{c$omp}, @code{*$omp} and @code{!$omp} directives in fixed form,
+@code{!$} conditional compilation sentinels in free form and @code{c$},
+@code{*$} and @code{!$} sentinels in fixed form, for Fortran. The flag also
+arranges for automatic linking of the OpenMP runtime library
+(@ref{Runtime Library Routines}).
+
+A complete description of all OpenMP directives accepted may be found in
+the @uref{http://www.openmp.org, OpenMP Application Program Interface} manual,

+
+In _most_ cases we can map this directly to @code{__thread}. Except
+that OMP allows constructors for C++ objects. We can either
+refuse to support this (how often is it used?) or we can
+implement something akin to .ctors.
+
+Even more ideally, this ctor feature is handled by extensions
+to the main pthreads library. Failing that, we can have a set
+of entry points to register ctor functions to be called.

+
+@node Implementing PRIVATE clause
+@section Implementing PRIVATE clause
+
+In association with a PARALLEL, or within the lexical extent
+of a PARALLEL block, the variable becomes a local variable in
+the parallel subfunction.
+
+In association with FOR or SECTIONS blocks, create a new
+automatic variable within the current function. This preserves
+the semantic of new variable creation.
+
+
+
+@node Implementing FIRSTPRIVATE LASTPRIVATE COPYIN and COPYPRIVATE clauses
+@section Implementing FIRSTPRIVATE LASTPRIVATE COPYIN and COPYPRIVATE clauses
+
+Seems simple enough for PARALLEL blocks. Create a private
+struct for communicating between parent and subfunction.
+In the parent, copy in values for scalar and "small" structs;
+copy in addresses for others TREE_ADDRESSABLE types. In the
+subfunction, copy the value into the local variable.
+
+Not clear at all what to do with bare FOR or SECTION blocks.
+The only thing I can figure is that we do something like
+
+@smallexample
+#pragma omp for firstprivate(x) lastprivate(y)
+for (int i = 0; i < n; ++i)
+ body;
+@end smallexample
+
+which becomes
+
+@smallexample
+@{
+ int x = x, y;
+
+ // for stuff
+
+ if (i == n)
+ y = y;
+@}
+@end smallexample
+
+where the "x=x" and "y=y" assignments actually have different
+uids for the two variables, i.e. not something you could write
+directly in C. Presumably this only makes sense if the "outer"
+x and y are global variables.
+
+COPYPRIVATE would work the same way, except the structure
+broadcast would have to happen via SINGLE machinery instead.
+
+
+
+@node Implementing REDUCTION clause
+@section Implementing REDUCTION clause
+
+The private struct mentioned in the previous section should have
+a pointer to an array of the type of the variable, indexed by the
+thread's @var{team_id}. The thread stores its final value into the
+array, and after the barrier the master thread iterates over the
+array to collect the values.

+Note that while it looks like there is trickyness to propagating
+a non-constant STEP, there isn't really. We're explicitly allowed
+to evaluate it as many times as we want, and any variables involved
+should automatically be handled as PRIVATE or SHARED like any other
+variables. So the expression should remain evaluable in the
+subfunction. We can also pull it into a local variable if we like,
+but since its supposed to remain unchanged, we can also not if we like.
+
+If we have SCHEDULE(STATIC), and no ORDERED, then we ought to be
+able to get away with no work-sharing context at all, since we can
+simply perform the arithmetic directly in each thread to divide up
+the iterations. Which would mean that we wouldn't need to call any
