[PR81611] accept copies in simple_iv_increment_p
If there are copies between the GIMPLE_PHI at the loop body and the
increment that reaches it (presumably through a back edge), still
regard it as a simple_iv_increment, so that we won't consider the
value in the back edge eligible for forwprop. Doing so would risk
making the phi node and the incremented conflicting value live
within the loop, and the phi node to be preserved for propagated
uses after the loop.

[AArch64] Fix sve/extract_[12].c for big-endian SVE
sve/extract_[12].c were relying on the target-independent optimisation
that removes a redundant vec_select, so that we don't end up with
things like:
dup v0.4s, v0.4s[0]
...use s0...
But that optimisation rightly doesn't trigger for big-endian targets,
because GCC expects lane 0 to be in the high part of the register
rather than the low part.
SVE breaks this assumption -- see the comment at the head of
aarch64-sve.md for details -- so the optimisation is valid for
both endiannesses. Long term, we probably need some kind of target
hook to make GCC aware of this.
But there's another problem with the current extract pattern: it doesn't
tell the register allocator how cheap an extraction of lane 0 is with
tied registers. It seems better to split the lane 0 case out into
its own pattern and use tied operands for the FPR<-SIMD case,
so that using different registers has the cost of an extra reload.
I think we want this for both endiannesses, regardless of the hook
described above.
Also, the gen_lowpart in this pattern fails for aarch64_be due to
TARGET_CAN_CHANGE_MODE_CLASS restrictions, so the patch uses gen_rtx_REG
instead. We're only creating this rtl in order to print it, so there's
no need for anything fancier.

Fix LRA subreg calculation for big-endian targets
LRA was using a subreg offset of 0 whenever constraints matched
two operands with different modes. That leads to an invalid offset
(and ICE) on big-endian targets if one of the modes is narrower
than a word. E.g. if a (reg:SI X) is matched to a (reg:QI Y),
the big-endian subreg should be (subreg:QI (reg:SI X) 3) rather
than (subreg:QI (reg:SI X) 0).
But this raises the issue of what the behaviour should be when the
matched operands occupy different numbers of registers. Should the
register numbers match, or should the locations of the lsbs match?
Although the documentation isn't clear, reload went for the second
interpretation (which seems the most natural to me):
/* On a REG_WORDS_BIG_ENDIAN machine, point to the last register of a
multiple hard register group of scalar integer registers, so that
for example (reg:DI 0) and (reg:SI 1) will be considered the same
register. */
So I think this means that we can/must use the lowpart offset
unconditionally, rather than trying to separate out the multi-register
case. This also matches the LRA handling of constant integers, which
already uses lowpart subregs.
The patch fixes gcc.target/aarch64/sve/extract_[34].c for aarch64_be.

rs6000: Fix safe-indirect-jump-[18].c
This patch merges the safe-indirect-jump-1.c and -8.c testcases,
since they do the same thing. On the 64-bit and AIX ABIs the indirect
call is not a sibcall, since there is code generated after the call
(the restore of r2). On the 32-bit non-AIX ABIs it is a sibcall.
* gcc.target/powerpc/safe-indirect-jump-1.c: Build on all targets.
Make expected output depend on whether we expect sibcalls or not.

[AArch64] Fix gcc.target/aarch64/subs_compare_[12].c
This patch fixes the testsuite failures gcc.target/aarch64/subs_compare_1.c and subs_compare_2.c
The tests check that we combine a sequence like:
sub w2, w0, w1
cmp w0, w1
into
subs w2, w0, w1
This is done by a couple of peepholes in aarch64.md.
Unfortunately due to scheduling and other optimisations the SUB and CMP
can come in a different order:
cmp w0, w1
sub w0, w0, w1
And the existing peepholes cannot catch that and we fail to combine the two.
This patch adds a peephole that matches the CMP as the first insn and the SUB as the second
and outputs a SUBS. This is almost equivalent to the existing peephole that matches SUB first and CMP second
except that it doesn't have the restriction that the output register of the SUB has to not be one of the input registers.
Remember "sub w0, w0, w1 ; cmp w0, w1" is *not* equivalent to: "subs w0, w0, w1"
but "cmp w0, w1 ; sub w0, w0, w1" is.
So this is what this patch does. It adds a peephole for the case above and one for the SUB-immediate variant
(because the SUB-immediate is represented as PLUS-of-negated-immediate and thus has different RTL structure).
Bootstrapped and tested on aarch64-none-linux-gnu.
* config/aarch64/aarch64.md: Add peepholes for CMP + SUB -> SUBS
and CMP + SUB-immediate -> SUBS.

Also, the float64 versions of these intrinsics are not supposed to be available on arm
so this patch slightly adjusts the test to not include them for aarch32.
In any case the entire test is XFAILed on arm, so this doesn't have any noticeable

[ARC] Add JLI support.
The ARCv2 ISA provides the JLI instruction, which is two-byte instructions
that can be used to reduce code size in an application. To make use of it,
we provide two new function attributes 'jli_always' and 'jli_fixed' which
will force the compiler to call the indicated function using a jli_s
instruction. The compiler also generates the entries in the JLI table for
the case when we use 'jli_always' attribute. In the case of 'jli_fixed'
the compiler assumes a fixed position of the function into JLI
table. Thus, the user needs to provide an assembly file with the JLI table
for the final link. This is usefully when we want to have a table in ROM
and a second table in the RAM memory.
The jli instruction usage can be also forced without the need to annotate
the source code via '-mjli-always' command.

compiler: deref receiver types in mangled names
This was the original intent, as reflected in the long comment at the
start of names.cc, but I forgot to implement it.
Also, remove a leading ".0" from the final name. That could occur for
a method whose receiver type starts with 'u', as in that case we
prepend a space to the mangled name, to avoid confusion with the
Unicode mangling, and the space turns into ".0".
Also, if the Unicode encoding would cause the final to start with
"..u" or "..U", add a leading underscore.
Patch gotest to not get fooled by some names.
The result of these changes is that all symbols start with a letter or
an underscore.

jit: remove some unused fields from recording::union_ (PR jit/81672)
gcc::jit::recording::union_ has some stray fields, which
are duplicates of those in the compound_type base class.
It looks like these have been present since the initial merger of the jit
branch to trunk (r217374), where it had three duplicate fields:
location *m_loc;
string *m_name;
fields *m_fields;
I removed the duplicate field "m_fields" in r219564 but missed the other
two.
This patch removes them.
