[arm] PR target/85733 Restore be8 linking behaviour for ARMv6-M and products deriving from its capabilities
My patch last year to automate passing the be8 flag to the linker had
a nasty flaw in that I forgot entirely that the ARMv6-M architecture
did not derive its capabilities directly from the ARMv6 capability
list, but was a new group of capabilities (since it needs to leave out
the ARM -- notm -- feature bit). The feature list defined was thus
missing the be8 bit. Furthermore, any product derived from that
feature group consequently lacked the be8 feature as well and this
included all ARMv7 and ARMv8 parts.
The fix is embarrassingly simple...

[arm] PR target/85606 prefer armv6s-m for armv6-m parts
When Arm introduced ARMv6-M there were two variants, ARMv6-M and
ARMv6S-M. The two differed only in support for the SVC instruction.
Later on SVC was then made a mandatory part of ARMv6-M and the
ARMv6S-M name was dropped. GCC and GAS, however still recognize both
names and at least some versions of GAS still distinguish between the
two.
To address this, this patch changes the architecture for the ARMv6-m
cortex parts (m0, m0plus, m1 and the variants will small multiply
units) to use the ARMv6S-M name in conjunction with the assembler.
This avoids problems with them rejecting code that was previously
accepted with older versions of GCC where we did not pass an explicit
architecture string through to the compiler when using -mcpu on the
command line.

The one for the prologue mflr did not have any value set, which means
use the SET that is in the insn pattern. This works fine, except when
some late pass decides to replace the SET_SRC -- this changes the
meaning of the REG_CFA_REGISTER! Such passes should not do these

could be argued that this defaulting is a design misfeature (it does
not save much space either, etc.)

shrink-wrap: Improve spread_components (PR85645)
In the testcase for PR85645 we do a pretty dumb placement of the
prologue/epilogue for the LR component: we place an epilogue for LR
before a control flow split where one of the branches clobbers LR
eventually, and the other does not. The branch that does clobber it
will need a prologue again some time later. Because saving and
restoring LR is a two step process---it needs to be moved via a GPR---
the backend emits CFI directives so that we get correct unwind
information. But both regcprop and regrename do not properly handle
such CFI directives leading to ICEs.
Now, neither of the two branches needs to have LR restored at all,
because both of the branches end up in an infinite loop.
This patch makes spread_component return a boolean saying if anything
was changed, and if so, it is called again. This obviously is finite
(there is a finite number of basic blocks, each with a finite number
of components, and spread_components can only assign more components
to a block, never less). I also instrumented the code, and on a
bootstrap+regtest spread_components made changes a maximum of two
times. Interestingly though it made changes on two iterations in
a third of the cases it did anything at all!

Add clobbers around IFN_LOAD/STORE_LANES
We build up the input to IFN_STORE_LANES one vector at a time.
In RTL, each of these vector assignments becomes a write to
subregs of the form (subreg:VEC (reg:AGGR R)), where R is the
eventual input to the store lanes instruction. The problem is
that RTL isn't very good at tracking liveness when things are
initialised piecemeal by subregs, so R tends to end up being
live on all paths from the entry block to the store. This in
turn leads to unnecessary spilling around calls, as well as to
excess register pressure in vector loops.
This patch adds gimple clobbers to indicate the liveness of the
IFN_STORE_LANES variable and makes sure that gimple clobbers are
expanded to rtl clobbers where useful. For consistency it also
uses clobbers to mark the point at which an IFN_LOAD_LANES
variable is no longer needed.

[arm] PR target/85658 Fix operator precedence errors in parsecpu.awk
There are a number of places in parsecpu.awk where I've managed to get
the operator precedence between ! and 'in' incorrect (! binds more
tightly). In most cases this just makes a consistency test
ineffective, but in a few cases it means we fail to correctly diagnose
errors by the user (for example, when passing an invalid cpu or
architecture name to configure. This patch fixes all the cases I
could find, based on searching for all uses of the two operators in
the same expression. The tweak to the API of check_fpu is to bring it
into line with the other check functions - it now returns the result
rather than printing it directly. The caller now does the printing,
in the same way that the chkarch and chkcpu commands do.

[AArch64] Predicated SVE comparison folds
This patch adds SVE patterns that combine a PTRUE-predicated
comparison with a separate AND. The main benefit is for
optimising ANDs with the loop predicate, as in the testcase.
However, one of the potential drawbacks is that it triggers
even for cases in which two naturally-parallel comparisons
are ANDed together. Whether that's a win or a less will
depend on the schedule, but it has the potential to be a win
more often than a loss.
The combine patterns are undeniably ugly. One way of getting
around them would be to allow 1->1 "splits" when combining
2 instructions, as well as 1->2 splits when combining more
than 2 instructions (although that wouldn't really be a split).
Another would be to have a way of defining target-specific
rtx simplifications. branches/ARM/sve-branch has a prototype
implementation of that, but it would need some clean-up before being
ready to submit. It would also be good to make it closer to the
match.pd style.
Until then, I think what the combine patterns are doing is the
"correct" implementation given the current infrastructure.

[AArch64] Use UNSPEC_MERGE_PTRUE for comparisons
This patch rewrites the SVE comparison handling so that it uses
UNSPEC_MERGE_PTRUE for comparisons that are known to be predicated
on a PTRUE, for consistency with other patterns. Specific unspecs
are then only needed for truly predicated floating-point comparisons,
such as those used in the expansion of UNEQ for flag_trapping_math.
The patch also makes sure that the comparison expanders attach
a REG_EQUAL note to instructions that use UNSPEC_MERGE_PTRUE,
so passes can use that as an alternative to the unspec pattern.
(This happens automatically for optabs. The problem was that
this code emits instruction patterns directly.)
No specific benefit on its own, but it lays the groundwork for
the next patch.
