This test has needlessly restrictive requirements. It tries to force a soft-float target and tries to run.

In fact, the test can be a run-time test for any target, and only the scan-assembler tests are specific to

Fix vect_def_type handling in x86 scatter support (PR 83940)
As Jakub says in the PR, the problem here was that the x86/built-in
version of the scatter support was using a bogus scatter_src_dt
when calling vect_get_vec_def_for_stmt_copy (and had since it
was added). The patch uses the vect_def_type from the original
call to vect_is_simple_use instead.
However, Jakub also pointed out that other parts of the load and store
code passed the vector operand rather than the scalar operand to
vect_is_simple_use. That probably works most of the time since
a constant scalar operand should give a constant vector operand,
and likewise for external and internal definitions. But it
definitely seems more robust to pass the scalar operand.
The patch avoids the issue for gather and scatter offsets by
using the cached gs_info.offset_dt. This is safe because gathers
and scatters are never grouped, so there's only one statement operand
to consider. The patch also caches the vect_def_type for mask operands,
which is safe because grouped masked operations share the same mask.
That just leaves the store rhs. We still need to recalculate the
vect_def_type there since different store values in the group can
have different definition types. But since we still have access
to the original scalar operand, it seems better to use that instead.

Check whether any statements need masking (PR 83922)
This PR is an odd case in which, due to the low optimisation level,
we enter vectorisation with:
outer1:
x_1 = PHI <x_3(outer2), ...>;
...
inner:
x_2 = 0;
...
outer2:
x_3 = PHI <x_2(inner)>;
These statements are tentatively treated as a double reduction by
vect_force_simple_reduction, but in the end only x_3 and x_2 are marked
as relevant. vect_analyze_loop_operations skips over x_3, leaving the
vectorizable_reduction check to a presumed future test of x_1, which
in this case never happens. We therefore end up vectorising x_2 only
(complete with peeling for niters!) and leave the scalar x_3 in place.
This caused a segfault in the support for fully-masked loops,
since there were no statements that needed masking. Fixed by
checking for that.
But I think this is also a flaw in vect_analyze_loop_operations.
Outer loop vectorisation reduces the number of times that the
inner loop is executed, so it wouldn't necessarily be valid
to leave the scalar x_3 in place for all vectorisable x_2.
There's already code to forbid that when x_1 isn't present:
/* FORNOW: we currently don't support the case that these phis
are not used in the outerloop (unless it is double reduction,
i.e., this phi is vect_reduction_def), cause this case
requires to actually do something here. */
I think we need to do the same if x_1 is present but not relevant.

Avoid ICE for nested inductions (PR 83914)
This testcase ICEd because we converted the initial value of an
induction to the vector element type even for nested inductions.
This isn't necessary because the initial expression is vectorised
normally, and it meant that init_expr was no longer the original
statement operand by the time we called vect_get_vec_def_for_operand.
Also, adding the conversion code here made the existing SLP conversion
redundant.

[arm] Fix gcc.target/arm/negdi-[12].c
These tests are failing for a silly reason. They scan for an occurrence of the NEGS instruction.
NEGS (and NEG in general) is a pre-UAL alias of RSB with an immediate of 0 and we only emit it
in one pattern: *thumb2_negsi2_short in thumb2.md. In all other instances of negation we emit
the modern RSB mnemonic. This causes needless differences in assembly output.
For example, for these testcases we emit NEG when compiling for -march=armv7-a, but for armv7ve
we emit RSB, causing the scan-assembler tests to fail.
This patch updates the *thumb2_negsi2_short pattern to use the RSB mnemonic and
fixes the flaky scan-assembler directives.
These tests now pass for my compiler configured with:
--with-cpu=cortex-a15 --with-fpu=neon-vfpv4 --with-float=hard --with-mode=thumb
Bootstrapped and tested on arm-none-linux-gnueabihf as well.

The scan-assembler tests here check for MOVS for Thumb1 and MOV for Thumb2,
but in fact there's no reason why we wouldn't generate MOVS for Thumb2 as well,
it really depends on a lot of optimisation decisions.
The only behaviour we want to test is that we move a 0 constant into a register
only once, which can be achieved with either MOV or MOVS.
Simplify the check by always checking for either MOV or MOVS.

[arm] PR target/65578: Fix builtin-bswap16-1.c and builtin-bswap-1.c
The builtin-bswap-1.c and builtin-bswap16-1.c are pretty annoying at the moment.
They force an explicit armv6 option that is a thumb1 target, so if you're testing a toolchain
configured with something like --with-cpu=cortex-a15 --with-float=hard --with-mode=thumb
you'll get those pesky errors about Thumb1 hard-float not being implemented, even though
the tests don't relate to floating-point functionality at all. I *think* this is also due
to the wrong order of dg-options and dg-require-effective-target directives that might
end up not doing a proper effective target check.
The solution in this patch is to commonise the code and create a couple of tests for each.
One tests an armv6t2 target. This allows us to test an ARM or a Thumb2 target.
The second one sets an armv6-m target, which is a Thumb1 target.
The dg-add-options machinery for arm_arch_v6m knows how to add the right -mfloat-abi=soft option.
With this patch we end up testing all of ARM, Thumb1, Thumb2 codegen whereas before we only
ever tried testing Thumb1, if the multilib options happened to line up just right, and would
give an ugly error otherwise. Now, if the multilib options don't allow the test it should just
appear as UNSUPPORTED.

PR go/83787
compiler: pass int to makechan, call makechan64 when appropriate
The update to 1.10beta1 changed makechan to take int instead of int64,
and added a makechan64 call for large values. Since the size is the
last argument to makechan, the old compiler which always passed a
64-bit int worked fine on 64-bit systems and little-endian 32-bit
systems, but broke on big-endian 32-bit systems. This CL fixes the
compiler to use the appropriate types.
This fixes GCC PR 83787.

analysis was not run for the runtime package. This CL removes
the hard-code, and lets the escape analysis decide. It is not
allowed for local variables and closures in the runtime to be
heap allocated. This CL adds the check that make sure that they
indeed do not escape.
The escape analysis is always run when compiling the runtime
now.

they will still give that nasty Thumb1 hard-float error when testing an implicit --with-mode=thumb
