A few places in the arm and aarch64 backends check whether an atomic operation needs acquire or release semantics.
A few places in the arm and aarch64 backends check whether an atomic
operation needs acquire or release semantics.
This is generally done with a check like
(is_mm_relaxed (model)
|| is_mm_consume (model)
|| is_mm_release (model))
In this patch we introduce two helper functions to make things a little
tidier.
There are a few places in the arm/ backend that check whether an
operation needs memory model semantics with an idiom that can now be
replaced with the new aarch_mm_needs_* functions, so we make that
replacement.
There is also some backslash removal to make things a little tidier.
Full bootstrap and regression test plus cross-compilation regression tests done
on arm-none-linux-gnueabihf.
Ok for trunk?

Fix EQ_ATTR_ALT size calculation (PR bootstrap/87417)
"r264537: Change EQ_ATTR_ALT to support up to 64 alternatives" changed
the format of EQ_ATTR_ALT from ii to ww. This broke the bootstrap on
32-bit systems, because the formula for rtx_code_size assumed that only
certain codes contain HOST_WIDE_INTs. This did not surface on 64-bit

Change EQ_ATTR_ALT to support up to 64 alternatives
On S/390 there is a need to support more than 32 instruction
alternatives per define_insn. Currently this is not explicitly
prohibited or unsupported: MAX_RECOG_ALTERNATIVES is equal 35, and,
futhermore, the related code uses uint64_t for bitmaps in most places.
However, genattrtab contains the logic to convert (eq_attr "attribute"
"value") RTXs to (eq_attr_alt bitmap) RTXs, where bitmap contains
alternatives, whose "attribute" has the corresponding "value".
Unfortunately, bitmap is only 32 bits.
When adding the 33rd alternative, this led to (eq_attr "type" "larl")
becoming (eq_attr_alt -
1050625 1), where -
1050625 == 0xffeff7ff. The
cleared bits 12, 21 and 32 correspond to two existing and one newly
added insn of type "larl". compute_alternative_mask sign extended this
to 0xffffffffffeff7ff, which contained non-existent alternatives, and
this made simplify_test_exp fail with "invalid alternative specified".
I'm not sure why it didn't fail the same way before, since the top bit,
which led to sign extension, should have been set even with 32
alternatives. Maybe simplify_test_exp was not called for "type"
attribute for some reason?
This patch widens EQ_ATTR_ALT bitmap to 64 bits, making it possible to
gracefully handle up to 64 alternatives. It eliminates the problem with
the 33rd alternative on S/390.

S/390: Fix conditional returns on z196+
S/390 epilogue ends with (parallel [(return) (use %r14)]) instead of
the more usual (return) or (simple_return). This sequence is not
recognized by the conditional return logic in try_optimize_cfg ().
This was introduced for processors older than z196, where it is
sometimes profitable to use call-clobbered register for returning
instead of %r14. On newer processors we always return via %r14,
for which the fact that it's used is already reflected by
EPILOGUE_USES. In this case a simple (return) suffices.
This patch changes return_use () to emit simple (return)s when
returning via %r14. The resulting sequences are recognized by the
conditional return logic in try_optimize_cfg ().

Use vectored writes when reporting errors and warnings.
When producing error and warning messages, libgfortran writes a
message by using many system calls. By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.
In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write. In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.

dumpfile.c: fix stray dump_loc output (PR tree-optimization/87309)
In r262891 I reimplemented this call:
dump_printf_loc (MSG_NOTE, loc, "=== %s ===\n", name);
in dump_begin_scope to use direct calls to dump_loc:
if (dump_file)
{
dump_loc (MSG_NOTE, dump_file, loc.get_location_t ());
fprintf (dump_file, "=== %s ===\n", name);
}
if (alt_dump_file)
{
dump_loc (MSG_NOTE, alt_dump_file, loc.get_location_t ());
fprintf (alt_dump_file, "=== %s ===\n", name);
}
However ::dump_loc doesn't filter with pflags and alt_flags.
This lead to stray output of the form:
test.cpp:1:6: note: test.cpp:1:11: note:
when using -fopt-info with "optimized" or "missed".
This patch adds this missing filtering, eliminating the stray partial
note output.

Propagate address spaces to builtins.
At present, pointers passed to builtin functions, including atomic operators,
are stripped of their address space properties. This doesn't seem to be
deliberate, it just omits to copy them.
Not only that, but it forces pointer sizes to Pmode, which isn't appropriate
for all address spaces.
This patch attempts to correct both issues. It works for GCN atomics and
