On passing +cdecp[0-7] extension to the -march string in command line options,
multilib linking is failing as mentioned in PR100856. This patch fixes this issue by
generating a separate canonical string by removing compiler options which are not

The warning is legitimate, even if that line cannot be reached because
we throw std::length_error before getting there. Since the invalid
length is deliberate (and mentioned in a comment) just suppress the
warning, so that the test can verify we get the exception.

While the patch passed bootstrap/regtest on the trunk, when trying to
backport it to 11 branch the bootstrap failed with
atree.ads:3844:34: size for "Node_Record" too small
errors. Turns out the error is not about size being too small, but actually
about size being non-constant, and comes from:
/* In a FIELD_DECL of a RECORD_TYPE, this is a pointer to the storage
representative FIELD_DECL. */
#define DECL_BIT_FIELD_REPRESENTATIVE(NODE) \
(FIELD_DECL_CHECK (NODE)->field_decl.qualifier)
/* For a FIELD_DECL in a QUAL_UNION_TYPE, records the expression, which
if nonzero, indicates that the field occupies the type. */
#define DECL_QUALIFIER(NODE) (FIELD_DECL_CHECK (NODE)->field_decl.qualifier)
so by setting up DECL_BIT_FIELD_REPRESENTATIVE in QUAL_UNION_TYPE we
actually set or modify DECL_QUALIFIER and then construct size as COND_EXPRs
with those bit field representatives (e.g. with array type) as conditions
which doesn't fold into constant.
The following patch fixes it by not creating DECL_BIT_FIELD_REPRESENTATIVEs
for QUAL_UNION_TYPE as there is nowhere to store them,
Shall we change tree.h to document that DECL_BIT_FIELD_REPRESENTATIVE
is valid also on UNION_TYPE?
I see:
tree-ssa-alias.c- if (TREE_CODE (type1) == RECORD_TYPE
tree-ssa-alias.c: && DECL_BIT_FIELD_REPRESENTATIVE (field1))
tree-ssa-alias.c: field1 = DECL_BIT_FIELD_REPRESENTATIVE (field1);
tree-ssa-alias.c- if (TREE_CODE (type2) == RECORD_TYPE
tree-ssa-alias.c: && DECL_BIT_FIELD_REPRESENTATIVE (field2))
tree-ssa-alias.c: field2 = DECL_BIT_FIELD_REPRESENTATIVE (field2);
Shall we change that to || == UNION_TYPE or do we assume all fields
are overlapping in a UNION_TYPE already?
At other spots (asan, ubsan, expr.c) it is unclear what will happen
if they see a QUAL_UNION_TYPE with a DECL_QUALIFIER (or does the Ada FE
lower that somehow)?

The <ranges> header defines simplified copies of some ranges algorithms
in order to avoid including the entirety of ranges_algo.h. A subsequent
patch is going to want to use ranges::search in <ranges> as well, and
that algorithm is more complicated compared to the other copied ones.
So rather than additionally copying ranges::search into <ranges>, this
patch splits out all the ranges algos used by <ranges> (including
ranges::search) from ranges_algo.h to ranges_util.h, and deletes the
simplified copies in <ranges>. This seems like the best place to
put these algorithms, as ranges_util.h is currently included only from
<ranges> and ranges_algo.h.

This implements the wording changes of P2325R3 "Views should not be
required to be default constructible". Changes are relatively
straightforward, besides perhaps those to __box (which now stands
for copyable-box instead of semiregular-box) and __non_propagating_cache.
For __box, this patch implements the recommended practice to also avoid
std::optional when the boxed type is nothrow_move/copy_constructible.
For __non_propagating_cache, now that it's used by split_view::_M_current,
we need to add assignment from a value of the underlying type to the
subset of the std::optional API implemented for the cache (needed by
split_view::begin()). Hence the new __non_propagating_cache::operator=
overload.
In passing, this fixes the undesirable list-init in the constructors of
the partial specialization of __box as reported in PR100475 comment #7.

This patch adds the support for the IEEE 128-bit floating point C minimum and
maximum instructions. The next patch will add the support for using the
compare and set mask instruction to implement conditional moves.
This patch does not try to re-use the code used for SF/DF min/max
support. It defines a separate insn for the IEEE 128-bit support. It
uses the code iterator <minmax> to simplify adding both operations.
GCC will not convert ternary operations into using min/max instructions
provided in this patch unless the user uses -Ofast. The next patch that adds
conditional move instructions will enable the ternary conversion in many cases.

This removes the helper functions added by r8-1294 to detect whether the
char_traits member functions can be evaluated at compile time. Instead,
we can just use __builtin_constant_evaluated directly, which is well
supported by non-GCC compilers by now.
As a result, there is a chance that those members will no longer be
usable in constant expressions when using old versions of non-GCC
compilers. Make the relevant feature test macros depend on the
availability of __builtin_constant_evaluated, so they are defined only
when the feature is actualyl available.
The new testcase from the PR is added to the libitm testsuite, because
that's where we can be sure it's OK to use the -fgnu-tm option.
