pass --enable-obsolete down to gcc/configure for auto-build.h
Configuring GCC for obsolete targets works as long as build = host.
When it isn't, --enable-obsolete is not passed down to the additional
build configure started by gcc/configure, used to generate
auto-build.h. The build configure fails and we end up without a
auto-build.h, but the host configure proceeds, so we only get a fatal
failure much later, when make realizes auto-build.h is not there and
there's no rule to create it.
This patch gets the host configure to fail when the build configure
does, leaving the temporary build configure dir behind for
investigation. It also arranges for --eanble-obsolete to be passed
down to the build configure.
Alas, the latter triggered a warning in the build configure because
--enable-obsolete is not a recognized configure option. That's not
reported in the host configure because of the
--disable-option-checking passed by the top-level configure, so I
arranged for that to be passed down to the build configure as well.
Finally, since my initial suspicion when investigating this failure
was that auto-build.h had been removed after configuration and there
was no rule to rebuild it, I'm adding rules to gcc/Makefile to get it
created or updated as needed. Since it is configure that creates it,
as run by e.g. config.status --recheck, and config.status is created
after auto-build.h, I've made config.status depend on auto-build.h,
and added a dummy rule to create auto-build.h. This would normally
not be enough to create a header when needed, but since Makefile
depends on config.status, and make first updates Makefile, it ends up
working, as long as nothing else that Makefile depends on requires
auto-build.h but not config.status. The config.status dependency and
the auto-build.h rule are only enabled in the cases in which
auto-build.h is actually used, namely when build != host.

[AArch64] Split gcc.target/aarch64/sve/vcond_4*
vcond_4.c combined too much stuff into one test, so that when we needed
to add XFAILs for one set of routines, we lost testing of others that
used the same instructions. This patch splits it into four:
vcond_4.c:
The main test for selects between a vector and a scalar, with all
elements having the same size.
After Prathamesh's fix for PR91272, we are now guaranteed to use the
conditionally-loaded vector as the "then" value and the scalar as the
"else" value.
vcond_4_zero.c:
Like vcond_4.c, but comparing with zero.
vcond_4_sel.c:
Tests for selects between two scalars, with all elements having
the same size. The optimisers can legitimately switch the "then"
and "else" order and adjust the comparison to match.
vcond_4_costly.c:
Like vcnod_4.c, but with mixed element sizes. The sequences tested
here will not be the preferred ones once we support mixtures of vector
sizes, but it still tests an important code path.
This means that vcond_4_run.c now only tests what's left in vcond_4.c,
but that seems OK, since the main point was to ensure correct exception
behaviour.
Similarly it means that vcond_5.c only tests what's left in vcond_4.c,
but that too is OK, since the point of the test was to compare the
default handling of each comparison in vcond_4.c with the
-fno-trapping-math equivalent.

[arm] Avoid using negative offsets for 'immediate' addresses when compiling for Thumb2
Thumb2 code now uses the Arm implementation of legitimize_address.
That code has a case to handle addresses that are absolute CONST_INT
values, which is a common use case in deeply embedded targets (eg:
void *p = (void*)0x12345678). Since thumb has very limited negative
offsets from a constant, we want to avoid forming a CSE base that will
then be used with a negative value.
This was reported upstream originally in
https://gcc.gnu.org/ml/gcc-help/2019-10/msg00122.html
For example,
void test1(void) {
volatile uint32_t * const p = (uint32_t *) 0x43fe1800;
p[3] = 1;
p[4] = 2;
p[1] = 3;
p[7] = 4;
p[0] = 6;
}
With the new code, instead of
ldr r3, .L2
subw r2, r3, #2035
movs r1, #1
str r1, [r2]

[arm] Pattern match insns for a + ~b + Carry
On ARM, the SBC instruction is defined as
Ra - Rb - ~C
where C is the carry flag. But -Rb = ~Rb + 1, so this is equivalent to
Ra + ~Rb + 1 - ~C
which then simplifies to
Ra + ~Rb + C
which is essentially an add-with-carry with one operand inverted. We
can define RTL patterns to match this. In thumb2 we can only match
when the operands are both registers, but in Arm state we can also use
RSC to match when Rn is either a constant or a shifted operand.
This overall simplifies some cases of 64-bit arithmetic, for example,
int64_t f (int64_t a, int64_t b) { return a + ~b; }

PR c++/84810 - constraints on lambdas
Attached is a patch that adds parsing of the optional requires-clause in a
lambda-expression and lambda-declarator. Additionally, shorthand constraints
from the template-parameter-list are now actually applied and constrain the
synthesized operator().
Previously we were not parsing the requires clauses at all and not saving
the shorthand constraints in the place expected by grokfndecl.
The trailing requires-clause is now also used to suppress synthesis of the
conversion to function pointer for non-capturing non-generic lambdas as per
expr.prim.lambda.closure/7.
This includes a fix to template_class_depth. Previously it was computing the
wrong depth for lambdas in the initializer of a static member of a class
template, exhibited by the concepts-lambda4 test which currently fails on
trunk. The bug was causing grokfndecl to use the constraints from the
template class for the lambda.
