Older versions of GCC emit empty .constructor/.destructor sections
whenever building for C++. In fact, these sections are only used for
kernel mode code - so don't emit them unless that's what we're

We need to mangle dots to avoid problems with -fgo-pkgpath=a.0.
That will confuse the name mangling, which assumes that names
entering the mangling cannot contain arbitrary dot characters.
We don't need to mangle other characters; go_encode_id will handle them.

ISO C2x adds decimal floating point as an optional standard feature.
This patch accordingly makes GCC accept DFP constants (DF, DD, DL, df,
dd, dl suffixes) in strict C2X mode, with a pedwarn-if-pedantic for
older standards and a warning with -Wc11-c2x-compat even in C2x mode
(which in turn requires -Wc11-c2x-compat to be newly passed through to
libcpp).

This addresses PR 91860 which has four testcases triggering internal errors.
The problem here is that in combine when handling debug insns, we are trying
to substitute
(sign_extend:DI (const_int 8160 [0x1fe0]))
as the value for
(reg:DI 78 [ _9 ])
in the debug insn
(debug_insn 29 28 30 2 (var_location:QI d (subreg:QI (reg:DI 78 [ _9 ]) 0)) "tmp4.c":11:5 -1
(nil))
This eventually triggers an abort because 8160 is not a sign-extended
QImode value.
In subst there is already code check for a CONST_INT inside a ZERO_EXTEND and
simplify it. This needs to be extended to also handle a SIGN_EXTEND the same
way.

ISO C2x adds decimal floating point as an optional standard feature.
This patch accordingly makes GCC accept the _Decimal* keywords in
strict C2x mode, using pedwarn_c11 to get a warning for
-Wc11-c2x-compat. (Constants, where the pedwarn is in libcpp, will be
dealt with separately.)
The _Decimal* keywords are marked with D_EXT, meaning they are not
considered keywords at all in strict conformance modes. This is
contrary to the normal practice for most implementation-namespace
keywords, which are accepted in all standards modes but with
appropriate pedwarns for older standards. This patch removes D_EXT
from those keywords so they are accepted as keywords for all
standards, consequently removing the gcc.dg/dfp/keywords-ignored-c99.c
test that is no longer valid.
(A new D_C2X for keywords will still be needed if any new keywords get
added that aren't in the implementation namespace for older standards;
there are proposals for such keywords, albeit as predefined macros
that might not actually need new keywords in the compiler in all
cases. If the DFP keywords end up as decimal32 etc., of course
appropriate compiler and testcase changes will be needed, and a
version of keywords-ignored-c99.c would make sense again with such
spellings.)

error_mark_node instead of aborting on overflow for named numbers.

deal with error_mark_node specifically.

on CONST_DECLs.

cp/
* decl2.c (grok_array_decl): For -fstrong-eval-order, when array ref
operands have been swapped and at least one operand has side-effects,
revert the swapping before calling build_array_ref.
* typeck.c (cp_build_array_ref): For non-ARRAY_TYPE array ref with
side-effects on the index operand, if -fstrong-eval-order use
save_expr around the array operand.
(cp_build_binary_op): For shifts with side-effects in the second
operand, wrap first operand into SAVE_EXPR and evaluate it before
the shift.
* semantics.c (handle_omp_array_sections_1): Temporarily disable
flag_strong_eval_order during OMP_CLAUSE_REDUCTION array section
processing.

GCC's <float.h> includes various macros for decimal floating-point
types, defined if __STDC_WANT_DEC_FP__, as defined in TS 24732.
TS 18661-2 and C2X make some changes to those macros. In TS 18661-2,
they are to be defined if __STDC_WANT_IEC_60559_DFP_EXT__, and the
*_SUBNORMAL_MIN macros are renamed to *_TRUE_MIN. In C2X, the macros
are to be defined whenever DFP is supported, without needing any
feature test macro to be defined.
This patch updates the header accordingly. There is no existing
predefined macro for whether the target supports DFP; rather than
adding a new macro for that purpose, this patch changes the predefined
macros used in <float.h> so that they are only defined when DFP is
supported and thus can be used as conditionals; this is the same way
predefined macros for _FloatN and _FloatNx types work. Although
formally TR 24732 and TS 18661-2 say nothing about implementations
lacking DFP support, it seems appropriate to avoid defining the macros
in <float.h>, in the absence of DFP support, even if the respective
feature test macros are defined.
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested
the c2x-float-no-dfp-* tests for aarch64-linux-gnu to make sure they
do pass in a no-DFP configuration.
gcc:
* ginclude/float.h [!__DEC32_MANT_DIG__]: Do not define DFP
macros.
[__STDC_WANT_IEC_60559_DFP_EXT__ || __STDC_VERSION__ > 201710L]:
Also define DFP macros for these conditions.
[!__STDC_WANT_DEC_FP__] (DEC32_SUBNORMAL_MIN, DEC64_SUBNORMAL_MIN,
DEC128_SUBNORMAL_MIN): Do not define.
[__STDC_WANT_IEC_60559_DFP_EXT__ || __STDC_VERSION__ > 201710L]
(DEC32_TRUE_MIN, DEC64_TRUE_MIN, DEC128_TRUE_MIN): New macros.
gcc/c-family:
* c-cppbuiltin.c (c_cpp_builtins): Do not define macros for DFP
types if DFP not supported.
gcc/testsuite:
* gcc.dg/c11-float-dfp-1.c, gcc.dg/c2x-float-no-dfp-1.c,
gcc.dg/c2x-float-no-dfp-2.c, gcc.dg/dfp/c2x-float-dfp-1.c,
