1534598063 libgomp: Handle NULL environ like pointer to NULL pointer [PR111413]
clearenv function just sets environ to NULL (after sometimes freeing it),
rather than setting it to a pointer to NULL, and our code was assuming
it is always non-NULL.

Fixed thusly, the change seems to be large but actually is just
+  if (environ)
     for (env = environ; *env != 0; env++)
plus reindentation.  I've also noticed the block after this for loop
was badly indented (too much) and fixed that too.

No testcase added, as it needs clearenv + dlopen.

18c8b56c7d OpenMP: Set default-device-var with OMP_TARGET_OFFLOAD=mandatory
OMP_TARGET_OFFLOAD=mandatory handling was before inconsistent. Hence, in
OpenMP 5.2 it was clarified/extended by having implications on the
default-device-var; additionally, omp_initial_device and omp_invalid_device
enum values/PARAMETERs were added; support for it was added
in r13-1066-g1158fe43407568 including aborting for omp_invalid_device and
non-conforming device numbers. Only the mandatory handling was missing.

Namely, while the default-device-var is usually initialized to value 0,
with 'mandatory' it must have the value 'omp_invalid_device' if and only if
zero non-host devices are available. (The OMP_DEFAULT_DEVICE env var
overrides this as it comes semantically after the initialization.)

To achieve this, default-device-var is now initialized to MIN_INT. If
there is no 'mandatory', it is set to 0 directly after env var parsing.
Otherwise, it is updated in gomp_target_init to either 0 or
omp_invalid_device. To ensure INT_MIN is never seen by the user, both
the omp_get_default_device API routine and omp_display_env (user call
and OMP_DISPLAY_ENV env var) call gomp_init_targets_once() in that case.

libgomp/ChangeLog:

	* env.c (gomp_default_icv_values): Init default_device_var to
	an nonconforming value - INT_MIN.
	(initialize_env): After env-var parsing, set default_device_var to
	device 0 unless OMP_TARGET_OFFLOAD=mandatory.
	(omp_display_env): If default_device_var is INT_MIN, call
	gomp_init_targets_once.
	* icv-device.c (omp_get_default_device): Likewise.
	* libgomp.texi (OMP_DEFAULT_DEVICE): Update init description.
	(OpenMP 5.2 Impl. Status): Mark OMP_TARGET_OFFLOAD=mandatory as 'Y'.
	* target.c (resolve_device): Improve error message device-num < 0
	with 'mandatory' and no no-host devices available.
	(gomp_target_init): Set default-device-var if INT_MIN.

288bc7b5d1 libgomp: Fix default value of GOMP_SPINCOUNT [PR 109062]
When OMP_WAIT_POLICY is not specified, current implementation will cause

will remain its uninitialized value. Initialize it to -1 to make
GOMP_SPINCOUNT behavior consistent with its description.

2a193e9df8 libgomp: Fix up build on mingw [PR107641]
Pointers should be first casted to intptr_t/uintptr_t before casting
them to another integral type to avoid warnings.
Furthermore, the function has code like
  else if (upper <= UINT_MAX)
    something;
  else
    something_else;
so it seems using unsigned type for upper where upper <= UINT_MAX is always
true is not intended.

e11babbfac libgomp: Appease some static analyzers [PR106906]
While icv_addr[1] = false; assignments where icv_addr has void *
element type is correct and matches how it is used (in those cases
the void * pointer is then cast to bool and used that way), there is no
reason not to add explicit (void *) casts there which are there already
for (void *) true.  And, there is in fact even no point in actually
doing those stores at all because we set that pointer to NULL a few
lines earlier.  So, this patch adds the explicit casts and then
comments those out to show intent.

9f2fca5659 OpenMP, libgomp: Environment variable syntax extension
This patch considers the environment variable syntax extension for
device-specific variants of environment variables from OpenMP 5.1 (see
OpenMP 5.1 specification, p. 75 and p. 639).  An environment variable (e.g.
OMP_NUM_TEAMS) can have different suffixes:

_DEV (e.g. OMP_NUM_TEAMS_DEV): affects all devices but not the host.
_DEV_<device> (e.g. OMP_NUM_TEAMS_DEV_42): affects only device with
number <device>.
no suffix (e.g. OMP_NUM_TEAMS): affects only the host.

In future OpenMP versions also suffix _ALL will be introduced (see discussion
https://github.com/OpenMP/spec/issues/3179). This is also considered in this
patch:

_ALL (e.g. OMP_NUM_TEAMS_ALL): affects all devices and the host.

The precedence is as follows (descending). For the host:

	1. no suffix
	2. _ALL

For devices:

	1. _DEV_<device>
	2. _DEV
	3. _ALL

That means, _DEV_<device> is used whenever available. Otherwise _DEV is used if
available, and at last _ALL.  If there is no value for any of the variable
variants, default values are used as already implemented before.

This patch concerns parsing (a), storing (b), output (c) and transmission to the
device (d):

(a) The actual number of devices and the numbering are not known when parsing
the environment variables.  Thus all environment variables are iterated and
searched for device-specific ones.
(b) Only configured device-specific variables are stored.  Thus, a linked list
is used.
(c) The output is done in omp_display_env (see specification p. 468f).  Global
ICVs are tagged with [all], see https://github.com/OpenMP/spec/issues/3179.
ICVs which are not global but aren't handled device-specific yet are tagged
with [host].  omp_display_env outputs the initial values of the ICVs.  That is
why a dedicated data structure is introduced for the inital values only
(gomp_initial_icv_list).
(d) Device-specific ICVs are transmitted to the device via GOMP_ADDITIONAL_ICVS.

4a0fed0c0c openmp: Handle OpenMP 5.1 simplified OMP_PLACES syntax
In addition to adding ll_caches and numa_domain abstract names
to OMP_PLACES syntax, OpenMP 5.1 also added one syntax simplification:
https://github.com/OpenMP/spec/issues/2080
https://github.com/OpenMP/spec/pull/2081
in particular that in the grammar place non-terminal is now
not only { res-list } but also res (i.e. a non-negative integer),
which stands as a shortcut for { res }
So, one can specify OMP_PLACES=0,4,8,12 with the meaning
OMP_PLACES={0},{4},{8},{12} or OMP_PLACES=0:4 instead of OMP_PLACES={0}:4
or OMP_PLACES={0},{1},{2},{3} etc.

This patch implements that.

c057ed9c52 openmp: Fix up strtoul and strtoull uses in libgomp
Yesterday when working on numa_domains, I've noticed because of a bug
in my patch a hang on a large NUMA machine.  I've fixed the bug, but
also discovered that the hang was a result of making wrong assumptions
about strtoul/strtoull.  All the uses were for portability setting
errno = 0 before the calls and treating non-zero errno after the call
as invalid input, but for the case where there are no valid digits at
all strtoul may set errno to EINVAL, but doesn't have to and with
glibc doesn't do that.  So, this patch goes through all the strtoul calls
and next to errno != 0 checks adds also endptr == startptr check.
Haven't done it in places where we immediately reject strtoul returning 0
the same as we reject errno != 0, because strtoul must return 0 in the
case where it sets endptr to the start pointer.  In some spots the code
was using errno = 0; x = strtoul (p, &p, 10); if (errno) { /*invalid*/ }
and those spots had to be changed to
errno = 0; x = strtoul (p, &end, 10); if (errno || end == p) { /*invalid*/ }
p = end;

e7ce32c783 openmp: Add support for OMP_PLACES=numa_domains
This adds support for numa_domains abstract name in OMP_PLACES, also new
in OpenMP 5.1.

Way to test this is
OMP_PLACES=numa_domains OMP_DISPLAY_ENV=true LD_PRELOAD=.libs/libgomp.so.1 /bin/true
and see what it prints on OMP_PLACES line.
For non-NUMA machines it should print a single place that covers all CPUs,

i.e.
/sys/devices/system/cpu/cpuN/cache/indexN/level
/sys/devices/system/cpu/cpuN/cache/indexN/shared_cpu_list
don't exist, is that because they have too old kernel and newer kernels
are fine or should I implement some fallback methods (which)?
E.g. on gcc112.fsffrance.org I see just shared_cpu_map and not shared_cpu_list
(with shared_cpu_map being harder to parse) and on another box I didn't even
see the cache subdirectories.

Way to test this is
OMP_PLACES=ll_caches OMP_DISPLAY_ENV=true LD_PRELOAD=.libs/libgomp.so.1 /bin/true
and see what it prints on OMP_PLACES line.

07dd3bcda1 openmp: Add omp_set_num_teams, omp_get_max_teams, omp_[gs]et_teams_thread_limit
OpenMP 5.1 adds env vars and functions to set and query new ICVs used
as fallback if thread_limit or num_teams clauses aren't specified on
teams construct.

The following patch implements those, though further work will be needed:
1) OpenMP 5.1 also changed the num_teams clause, so that it can specify
   both lower and upper limit for how many teams should be created and
   changed the meaning when only one expression is provided, instead of
   num_teams(expr) in 5.0 meaning num_teams(1:expr) in 5.1, it now means
   num_teams(expr:expr), i.e. while previously we could create 1 to expr
   teams, in 5.1 we have some low limit by default equal to the single
   expression provided and may not create fewer teams.
   For host teams (which we don't currently implement efficiently for
   NUMA hosts) we trivially satisfy it now by always honoring what the
   user asked for, but for the offloading teams I think we'll need to
   rethink the APIs; currently teams construct is just a call that returns
   and possibly lowers the number of teams; and whenever possible we try
   to evaluate num_teams/thread_limit already on the target construct
   and the GOMP_teams call just sets the number of teams to the minimum
   of provided and requested teams; for some cases e.g. where target
   is not combined with teams and num_teams expression calls some functions
   etc., we need to call those functions in the target region and so it is
   late to figure number of teams, but also hw could just limit what it
   is willing to create; in that case I'm afraid we need to run the target
   body multiple times and arrange for omp_get_team_num () returning the
   right values
2) we need to finally implement the NUMA handling for GOMP_teams_reg
3) I now realize I haven't added some testcase coverage, will do that
   incrementally
4) libgomp.texi needs updates for these new APIs, but also others like
   the allocator

432de08498 OpenMP 5.1: Add proc-bind 'primary' support
In OpenMP 5.1 "master thread" was changed to "primary thread" and
the proc_bind clause and the OMP_PROC_BIND environment variable
now take 'primary' as argument as alias for 'master', while the
latter is deprecated.
This commit accepts 'primary' and adds the named constant
omp_proc_bind_primary and changes 'master thread' in the
documentation; however, given that not even OpenMP 5.0 is
fully supported, omp_display_env and the dumps currently
still output 'master' and there is no deprecation warning
when using the 'master' in the proc_bind clause.

	* c-parser.c (c_parser_omp_clause_proc_bind): Accept
	'primary' as alias for 'master'.

gcc/cp/ChangeLog:

	* parser.c (cp_parser_omp_clause_proc_bind): Accept

I can't reproduce that, but I fail to see why we need two separate
variables, one with actual value and one tracking if the value is valid.

So, I'm going with:

	* env.c (parse_target_offload): Change new_offload var type to int,
	preinitialize to -1, remove found var and test new_offload != -1
	instead of found.

1bfc07d150 openmp: Implement support for OMP_TARGET_OFFLOAD environment variable
This implements support for the OMP_TARGET_OFFLOAD environment variable
introduced in the OpenMP 5.0 standard, which controls how offloading
is handled.  It may be set to MANDATORY (abort if offloading cannot be
performed), DISABLED (no offloading to devices) or DEFAULT (offload to
device if possible, fall back to host if not).

8949b985db openmp: Add support for the omp_get_supported_active_levels runtime library routine
This patch implements the omp_get_supported_active_levels runtime routine
from the OpenMP 5.0 specification, which returns the maximum number of
active nested parallel regions supported by this implementation.  The
current maximum (set using the omp_set_max_active_levels routine or the
OMP_MAX_ACTIVE_LEVELS environment variable) cannot exceed this number.

800bcc8c00 openmp: Add basic library allocator support.
This patch adds very basic allocator support (omp_{init,destroy}_allocator,
omp_{alloc,free}, omp_[sg]et_default_allocator).
The plan is to use memkind (likely dlopened) for high bandwidth memory, but
that part isn't implemented yet, probably mlock for pinned memory and see
what other options there are for other kinds of memory.
For offloading targets, we need to decide if we want to support the
dynamic allocators (and on which targets), or if e.g. all we do is at compile
time replace omp_alloc/omp_free calls with constexpr predefined allocators
with something special.

And allocate directive and allocator/uses_allocators clauses are future work
too.
