[Patch combine] Don't create vector mode ZERO_EXTEND from subregs
The code in simplify set to handle transforming the paradoxical subreg
expression:
(set FOO (subreg:M (mem:N BAR) 0))
in to:
(set FOO (zero_extend:M (mem:N BAR)))
Does not consider the case where M is a vector mode, allowing it to
construct (for example):
(zero_extend:V4SI (mem:SI))

[SFN] stabilize find_bb_boundaries
If find_bb_boundaries is given a block with zero or one nondebug insn
beside debug insns, it shouldn't purge dead edges, because without
debug insns we wouldn't purge them at that point. Doing so may change
the order in which edges are processed, and ultimately lead to
different transformations to the CFG and then to different
optimizations.
We shouldn't, however, retain debug insns after control flow insns, so
if we find debug insns after a single insn that happens to be a
control flow insn, do the debug insn cleanups, but still refrain from
purging dead edges at that point.

nonbind markers.
In a seemingly mechanical way, it adjusts several uses of the macros

Expensive selftests: torture testing for fix-it boundary conditions (PR c/82050)
This patch adds selftest coverage for the fix for PR c/82050.
The selftest iterates over various "interesting" column and line-width
values to try to shake out bugs in the fix-it printing routines, a kind
of "torture" selftest.
Unfortunately this selftest is noticably slower than the other selftests;
adding it to diagnostic-show-locus.c led to:
-fself-test: 40218 pass(es) in 0.172000 seconds
slowing down to:
-fself-test: 97315 pass(es) in 6.109000 seconds
for an unoptimized build (e.g. when hacking with --disable-bootstrap).
Given that this affects the compile-edit-test cycle of the "gcc"
subdirectory, this felt like an unacceptable amount of overhead to add.
I attempted to optimize the test by reducing the amount of coverage, but
the test seems useful, and there seems to be a valid role for "torture"
selftests.
Hence this patch adds a:
gcc.dg/plugin/expensive_selftests_plugin.c
with the responsibility for running "expensive" selftests, and adds the
expensive test there. The patch moves a small amount of code from
selftest::run_tests into a helper class so that the plugin can print
a useful summary line (to reassure us that the tests are actually being
run).
With that, the compile-edit-test cycle of the "gcc" subdir is unaffected;
the plugin takes:
expensive_selftests_plugin: 26641 pass(es) in 3.127000 seconds
which seems reasonable within the much longer time taken by "make check"
(I optimized some of the overhead away, hence the reduction from 6 seconds
above down to 3 seconds).

combine: Fix PR83304
In PR83304 two insns are combined, where the I2 uses a register that
has a REG_DEAD note on an insn after I2 but before I3. In such a case
move_deaths should move that death note. But move_deaths only looks
at the reg_stat[regno].last_death insn, and that field can be zeroed
out (previously, use_crosses_set_p would prevent the combination in
this case).

we have to find if there is a REG_DEAD note.

[arm] PR target/83206: Make native driver select fp-capable armv6 cores
A quirk in the historical naming of some ARMv6 products means that the
main CPU name implies the presence or otherwise of the floating point unit.
This causes problems when using -mfpu=auto with -mcpu=native: the driver is
picking a CPU that does not support a floating-point unit, even though
one may well exist.
This patch addresses this by selecting the FP-capable names so that FP
instructions will be generated if the other options suggest this is
permitted.
Note that a more complete fix is really needed here to look up the
FP/simd capabilities and append the appropriate capability extensions.
This will be the subject of some follow-up patches.

[arm] Don't strip off all architecture features from -march passed to assembler
When GCC invokes the assembler it generates a sanitized version of the
user-specified -march option to pass through, since the assembler does
not understand all the new FPU-related architectural options.
Unfortunately it goes too far and strips off all the architectural
extensions, including some that are unrelated to the -mfpu variant
selected.
Again, this doesn't really matter when compiling C code because the
compiler will override the command-line specified architecture with
directives in the assembly file itself, but when using the compiler
driver to invoke the assembler the only indiciation of the desired
architecture might come from the command line.
We fix this by adjusting the canonicalization pass to remove any
option that only specifies features that can be expressed by -mfpu
(any that go beyond that are already supported by the assembler). We
do have to take care to re-order the options, though as the assembler
expects feature options to be in a canonical order (unlike the
compiler, where ordering is handled left-to-right: there's only a
difference if there are negation options, but a canonicalized
architecture string shouldn't have any of those). We do this by
recording which options we need and then sorting the final list
alphabetically.

[arm] Generate a -mfpu= option for passing to the assembler
When gcc runs with the new -mfpu=auto option (either explicitly or
when that's the default behaviour) then this option is not passed
through to the assembler as we cannot rely on the assembler
understanding it (currently it doesn't understand it at all, but in
future that might change). That means that the assembler falls back
to its builtin default, which may not correspond to what the user
expected based on the command-line options they passed.
Normally that wouldn't matter because assembler files generated by the
compiler will contain explicit directives that set the FPU type
directly and override any internal defaults; but when the compiler
driver is used to invoke the assembler directly (because the source
file ends in .s or .S) then this might cause a problem if that assumes
the FPU matches the compiler.
To address this, this patch makes the driver construct a -mfpu= option
for the assembler in the same way as the compiler generates an
internal .fpu directive. As mentioned, this makes no difference if
the assembler file explicitly overrides the command line options, but
helps in the case where this is implicit.

Allow _Alignas in compound literals (C11 DR#444).
C11 DR#444 dealt with how C11 intended to allow alignment specifiers
on struct and union members, but failed to include that in the syntax.
The final resolution of that DR also allows alignment specifiers in
type names in compound literals (in order to apply an increased
alignment to the unnamed object created by the compound literal), but
not other cases of type names.
This patch implements allowing alignment specifiers in compound
literals and adds tests for the resolution of the DR (including that
they are allowed on struct and union members, which GCC already
implemented). Because the parser has to parse the parenthesized type
name of a compound literal before it can tell that it's a compound
literal (rather than, depending on the context, a cast expression or
sizeof (type-name) or _Alignof (type-name)), this means _Alignas
specifiers are allowed syntactically in those contexts and then an
error is given once it's known to be an invalid use (whereas _Alignas
specifiers are disallowed syntactically in other contexts where type
names can occur and a compound literal is not possible).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Three related regression fixes:
- We can't use asserts like:
gcc_assert (GET_MODE_SIZE (mode) == 16);
in aarch64_print_operand because it could trigger for invalid user input.
- The output_operand_lossage in aarch64_print_address_internal:
output_operand_lossage ("invalid operand for '%%%c'", op);
wasn't right because "op" is an rtx_code enum rather than the
prefix character.
- aarch64_print_operand_address shouldn't call output_operand_lossage
(because it doesn't have a prefix code) but instead fall back to
output_addr_const.

Make more use of VECTOR_CST_ENCODED_ELT
This patch makes various bits of code operate directly on the new
VECTOR_CST encoding, instead of using VECTOR_CST_ELT on all elements
of the vector.
Previous patches handled operations that produce a new VECTOR_CST,
while this patch handles things like predicates. It also makes
print_node dump the encoding instead of the full vector that
the encoding represents.

New VECTOR_CST layout
This patch uses a simple compression scheme to represent the contents
of a VECTOR_CST using its leading elements. There are three formats:
1) a repeating sequence of N values. This is encoded using the first
N elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N values, such as:
{ 1, 2, 0, 0, 0, 0, ... }. This is encoded using the first 2*N
elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N interleaved linear series,
such as: { 0, 0, 8, 10, 9, 11, 10, 12, ... }. This is encoded
using the first 3*N elements. In practice the foreground values
are often part of the same series as the background values,
such as: { 1, 11, 2, 12, 3, 13, ... }.
This reduces the amount of work involved in processing simple
vector constants and means that the encoding extends naturally
to variable-length vectors.
