+/* Lowering of OpenMP parallel and workshare constructs proceeds in two

--- /dev/null
+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)

+
+ =>
+
+ datap = GOMP_single_copy_start ();
+ if (datap == NULL)

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
