Arm: Update tests after register allocation changes. (PR/target 88560)
After the register allocator changes of r268705 we need to update a few tests
with new output.
In all cases the compiler is now generating the expected code, since the tests
are all float16 testcases using a hard-floar abi, we expect that actual fp16
instructions are used rather than using integer loads and stores. Because of
we also save on some mov.f16s that were being emitted before to move between
the two.
The aapcs cases now match the f32 cases in using floating point operations.

[RS6000] Correct save_reg_p
Fixes lack of r30 save/restore on

These are both caused by save_reg_p returning false when the pic

S/390: Introduce jdd constraint
Implementation of section anchors in S/390 back-end added in r266741
broke jump labels in S/390 Linux kernel [1]. Currently jump labels
pass global variable addresses to .quad directive in inline assembly
using "X" constraint. In the past this used to produce regular symbol
references, however, after r266741 we sometimes get values like
(plus (reg) (const_int)), where (reg) points to a section anchor.
Strictly speaking, this is still correct, since "X" accepts anything.
Thus, now we need another way to support jump labels.
The existing "i" constraint cannot be used, since with -fPIC it must
not accept non-local symbols, however, jump labels do require that,
e.g. __tracepoint_xdp_exception from kernel proper might be referenced
from kernel modules.
The existing "ZL" constraint cannot be used for the same reason.
The existing "b" constraint cannot be used because of the way
expand_asm_stmt works. It deduces whether the constraint allows
regs, subregs or mems, and processes asm operands differently based on
that. "b" is supposed to accept values like (mem (symbol_ref)), and
there appears to be no way to explain to expand_asm_stmt that for "b"
mem's address must not be in a register.
This patch introduces the new machine-specific constraint named "jdd" -
"j" prefix is already used for constants, and "d" stands for "data".
It accepts anything that fits into the data section, whether or not
this might require a relocation, that is, anything that passes
CONSTANT_P check.

Fix more ICEs in -fsave-optimization-record (PR tree-optimization/89235)
PR tree-optimization/89235 reports an ICE inside -fsave-optimization-record
whilst reporting the inlining chain of of the location_t in the
vect_location global.
This is very similar to PR tree-optimization/86637, fixed in r266821.
The issue is that the inlining chains are read from the location_t's
ad-hoc data, referencing GC-managed tree blocks, but the former are
not GC roots; it's simply assumed that old locations referencing dead
blocks never get used again.
The fix is to reset the "vect_location" global in more places. Given
that is a somewhat subtle detail, the patch adds a sentinel class to
reset vect_location at the end of a scope. Doing it as a class
simplifies the task of ensuring that the global is reset on every
exit path from a function, and also gives a good place to signpost
the above subtlety (in the documentation for the class).
The patch also adds test cases for both of the PRs mentioned above.

[AArch64] Change representation of SABD in RTL
Richard raised a concern about the RTL we use to represent the AdvSIMD SABD
(vector signed absolute difference) instruction.
We currently represent it as ABS (MINUS op1 op2).
This isn't exactly what SABD does. ABS treats its input as a signed value
and returns the absolute of that.
For example:
(sabd:QI 64 -128) == 192 (unsigned) aka -64 (signed)
whereas
(minus:QI 64 -128) == 192 (unsigned) aka -64 (signed), (abs ...) of that is 64.
A better way to describe the instruction is with MINUS (SMAX (op1 op2) SMIN (op1 op2)).
This patch implements that, and also implements similar semantics for the UABD instruction
that uses UMAX and UMIN.
That way for the example above we'll have:
(minus:QI (smax:QI (64 -128)) (smin:QI (64 -128))) == (minus:QI 64 -128) == 192 (or -64 signed) which matches

[Patch] [arm] Fix 88714, Arm LDRD/STRD peepholes.
These peepholes match a pair of SImode loads or stores that can be
implemented with a single LDRD or STRD instruction.
When compiling for TARGET_ARM, these peepholes originally created a set
pattern in DI mode to be caught by movdi patterns.
This approach failed to take into account the possibility that the two
matched insns operated on memory with different aliasing information.
The peepholes lost the aliasing information on one of the insns, which
could then cause the scheduler to make an invalid transformation.
This patch changes the peepholes so they generate a PARALLEL expression
of the two relevant loads or stores, which means the aliasing
information of both is kept. Such a PARALLEL pattern is what the
peepholes currently produce for TARGET_THUMB2.
In order to match these new insn patterns, we add two new define_insn's. These
define_insn's use the same checks as the peepholes to find valid insns.
Note that the patterns now created by the peepholes for LDRD and STRD
are very similar to those created by the peepholes for LDM and STM.
Many patterns could be matched by the LDM and STM define_insns, which
means we rely on the order the define_insn patterns are defined in the
machine description, with those for LDRD/STRD defined before those for
LDM/STM.
The difference between the peepholes for LDRD/STRD and those for LDM/STM
are mainly that those for LDRD/STRD have some logic to ensure that the
two registers are consecutive and the first one is even.

[arm] Use neon_dot_q type for 128-bit V[US]DOT instructions where appropriate
For the Dot Product instructions we have the scheduling types neon_dot and neon_dot_q for the 128-bit versions.
It seems that we're only using the former though, not assigning the neon_dot_q type anywhere.
This patch fixes that by adding the <q> mode attribute suffix to the type, similar to how we do it for other
types in neon.md.

[PR86218] handle ck_aggr in compare_ics in both and either conversion
Because of rank compares, and checks for ck_list, we know that if we
see user_conv_p or ck_list in ics1, we'll also see it in ics2. This
reasoning does not extend to ck_aggr, however, so we might have
ck_aggr conversions starting both ics1 and ics2, which we handle
correctly, or either, which we likely handle by crashing on whatever
path we take depending on whether ck_aggr is in ics1 or ics2.
We crash because, as we search the conversion sequences, we may very
well fail to find what we are looking for, and reach the end of the
sequence, which is unexpected in all paths.
This patch arranges for us to take the same path when ck_aggr is in
ics2 only that we would if it was in ics1 (regardless of ics2), and it
deals with not finding the kind of conversion we look for there.
I've changed the type of the literal constant in the testcase, so as
to hopefully make it well-formed. We'd fail to reject the narrowing
conversion in the original testcase, but that's a separate bug.

In the recent change to use atomic_compare_exchange_n I thought we

Fix locations in conversion_null_warnings (PR c++/71302)
PR c++/71302 reports that g++ shows poor locations for
-Wzero-as-null-pointer-constant for pointers in function calls,
using the close parenthesis of the call, rather than showing the
pertinent argument.
This particular case was fixed in GCC 8, but regressed on trunk
in r260973.
This patch fixes the regression, and adds column numbers to the
test cases (where they're correct) to avoid regressing them in the
future. There are still various places where the locations aren't
correct, but fixing them isn't stage 4 material.
