74c9882b80 openmp: Change omp_get_initial_device () to match OpenMP 5.1 requirements
> Therefore, I think until omp_get_initial_device () value is changed, we

The following so far untested patch implements that change.

OpenMP 4.5 said for omp_get_initial_device:
The value of the device number is implementation defined. If it is between 0 and one less than
omp_get_num_devices() then it is valid for use with all device constructs and routines; if it is
outside that range, then it is only valid for use with the device memory routines and not in the
device clause.
and OpenMP 5.0 similarly, but OpenMP 5.1 says:
The value of the device number is the value returned by the omp_get_num_devices routine.

As the new value is compatible with what has been required earlier, I think
we can change it already now.

c0baff9be3 vxworks float EFs not precise enough -> use long float
Some acats-4 tests that check the precision of Float elementary
functions fail with vxworks 7.2's implementations of single-precision
math functions.

This patch arranges for us to bypass the single-precision functions,
and use the Aux_Long_Float implementation, based on the double-typed
calls from the C library, for Float and Short_Float.

9f4e1d10eb Use Aux_Long_Long_Float wraplf for sparc*-sun-solaris too
Like aarch64-* and ppc*-linux-gnu, sparc*-sun-solaris has
Long_Long_Float mapped to double rather than long double, so the
intrinsics in the default version of a-nallfl.ads have mismatching
types.  Adopt the wraplf workaround for it as well.

f72d7f7c2c aarch64-* and ppc*-linux-gnu long long float/long double mismatch
Some platforms have failed to build because long long float is mapped
to double rather than long double, and then the attempts to import
intrinsics for long double in Aux_Long_Long_Float raise warnings
turned into errors.

This patch is a work around for the mismatch, arranging for
Aux_Long_Long_Float to map to Aux_Long_Float.

439407aa2c syscall: only compile ptrace varargs shim on Linux
Only compile the __go_ptrace varargs shim on Linux to avoid compilation
failures on some other platforms. The C ptrace function is not entirely
portable (e.g., NetBSD has `int data` instead of `void* data`), and so
far Linux is the only platform that needs the varargs shim.

Additionally, make the types in the ptrace and raw_ptrace function
declarations match. This makes it more clear that the only difference
between the two is that calls via the former are allowed to block while
calls via the latter are not.

84cc3370d6 rs6000: MMA type causes an ICE in ranger pass due to incompatible types
PR97360 shows a problem in how we create our PXI and POI modes that cause
an ICE in the ranger pass.  The problem seems to be that the extra call
to build_distinct_type_copy() also creates new TYPE_{MIN,MAX}_VALUEs that
are not compatible/the same as the base type itself.  The simple "fix" is
to actually remove the unneeded build_distinct_type_copy(), since according
to richi, the types returned from make_unsigned_type() are already distinct.

caaa218f91 Inline functions with builtin_constant_p more agressively.
This patch implements heuristics that increases inline limits (by the hints
mechanism) for inline functions that use builtin_constant_p on parameter. Those
are very likely intended to be always inlined and simplify after inlining.

The PR is about a function that we used to inline with
 --param inline-insns-single=200 but with new default of 70 for -O2 we no longer
do so.  Hints are currently configured to bump the bound up twice, so we
get limit of 140 that is still not enough to inline the particular testcase
but it should help in general.  I can implement a stronger bump if that seems
useful (maybe it is). The example is bit operation written as a decision chain
with 64 conditions.
This blows up the limit on number of conditions we track per funtion (which is
30) and thus the size/time estimates are not working that well.

6bd2f2d080 Remove interfering default #undefs from vx-common.h
undef'ing LIB_SPEC and especially LINK_SPEC here is unneccesary and
inteferes with the definition of LINK_SPEC for the bi-arch'd ppc*-vx7r2
target which uses the linux64 LINK_SPEC

1786798090 Introduce vxworks7r2 support for ppc and ppc64
This change introduces support for the most recent versions
of VxWorks on PowerPC targets, for both 32 and 64 bit thanks
to a bi-arch setup.

The system compilers are essentially configured as Linux
toolchains with only a few specificities and we replicate
that model here.

The most visible specificities are the use of secureplt by
default, the pre-definition of some macros that the system
headers still rely on (_VX_CPU and _VX_CPU_FAMILY, for example),
and of course some variations related to the so VxWorks typical
kernel vs RTP mode distinction.

In addition to the introduction of config.gcc and libgcc
configuration chunks, much inspired by the linux ones, the
change

- Reworks rs6000/vxworks.h file to feature bits common to the
  Vx6 and Vx7 port then a separate section for each, where the
  Vx7 part is very short as we rely on the Linux definitions
  for most things.

- Adjusts the CPU macro predefinitions in CPP_SPEC to resort
  to "_VX_CPU" instead of "CPU" for Vx7, to better match the
  more recent system headers expectations,

- Adds a cpu definition case for e6500.

- Changes to the use SUB3TARGET_OVERRIDE_OPTIONS instead of
  SUBSUBTARGET_OVERRIDE_OPTIONS for specifics, so we don't
  override the Linux's version of the latter for vx7.

2020-10-20  Douglas Rupp  <rupp@adacore.com>

gcc/
	* config.gcc (powerpc*-wrs-vxworks7r*): New case.
	* config/rs6000/vxworks.h: Rework to handle VxWorks7.
	Refactor as common bits + vx6 vs vx7 ones. For the
	latter, rely essentially on the Linux configuration
	and adjust CPU to _VX_CPU in CPP_SPEC. Add a case
	for e6500. Use SUB3TARGET_OVERRIDE_OPTIONS for specifics
	to preserve the Linux SUBSUBTARGET_OVERRIDE_OPTIONS
	for vx7.

a186ab670e libstdc++: Make structured bindings always work for subranges [PR 97512]
The definition of ranges::subrange was moved to the new
<bits/ranges_util.h> header so that it could be used in <algorithm>
without including the whole of <ranges>. However, the tuple-like support
that enables subrange to be used with structured bindings was left in
<ranges>. This is arguably conforming (to use a subrange you should
include <ranges>) but it's inconvenient and probably confusing.

This change makes the tuple-like support available whenever subrange
itself is available.

5244b4af5e phiopt: Optimize x ? __builtin_clz (x) : 32 in GIMPLE [PR97503]
While we have at the RTL level noce_try_ifelse_collapse combined with
simplify_cond_clz_ctz, that optimization doesn't always trigger because
e.g. on powerpc there is an define_insn to compare a reg against zero and
copy that register to another one and so we end up with a different pseudo
in the simplify_cond_clz_ctz test and punt.

For targets that define C?Z_DEFINED_VALUE_AT_ZERO to 2 for certain modes,
we can optimize it already in phiopt though, just need to ensure that
we transform the __builtin_c?z* calls into .C?Z ifns because my recent
VRP changes codified that the builtin calls are always undefined at zero,
while ifns honor C?Z_DEFINED_VALUE_AT_ZERO equal to 2.
And, in phiopt we already have popcount handling that does pretty much the
same thing, except for always using a zero value rather than the one set
by C?Z_DEFINED_VALUE_AT_ZERO.

So, this patch extends that function to handle not just popcount, but also
clz and ctz.

028a407463 Simplify CFG copying tables
This simplifies the maps between original and new basic blocks and
loops as used for CFG copying.  Instead of using a pointer hash
table to allocated mapping entries use a hash_map with int_hash,
removing the indirection and code duplication.  We can use -1 and
-2 as empty/deleted values as those are not valid basic-block
indices or loop numbers.

I can't reproduce that, but I fail to see why we need two separate
