The _M_add_ref_lock() and _M_add_ref_lock_nothrow() members of
_Sp_counted_base are very similar, except that the former throws an
exception when the use count is zero and the latter returns false. The
former (and its callers) can be implemented in terms of the latter.
This results in a small reduction in code size, because throwing an
exception now only happens in one place.

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.

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.

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
2020-10-21 Douglas Rupp <rupp@adacore.com>
gcc/
* config/vx-common.h (LINK_SPEC, LIB_SPEC): Remove #undef.
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.

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.

Inductions are not vectorized as cycle but materialized from SCEV data.

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.
