lra_insn_reg and lra_operand_data have both a bitmask of earlyclobber
alternatives and an overall boolean. The danger is that we then test
the overall boolean when really we should be testing for a particular
alternative. This patch gets rid of the boolean and tests the mask
against zero when we really do need to test "any alternative might
be earlyclobber". (I think the only instance of that is the
LRA_UNKNOWN_ALT handling in lra-lives.c:reg_early_clobber_p.)
This is needed (and tested) by an upcoming SVE patch.

This patch extends the FMA handling in tree-ssa-math-opts.c so
that it can cope with conditional multiplications as well as
unconditional multiplications. The addition or subtraction must then
have the same condition as the multiplication (at least for now).
E.g. we can currently fold:
(IFN_COND_ADD cond (mul x y) z fallback)
-> (IFN_COND_FMA cond x y z fallback)
This patch also allows:
(IFN_COND_ADD cond (IFN_COND_MUL cond x y <whatever>) z fallback)

inchash:#️⃣:add_wide_int operated directly on the raw encoding
of the wide_int, including any redundant upper bits. The problem
with that is that the upper bits are only defined for some wide-int
storage types (including wide_int itself). wi::to_wide(tree) instead
returns a value that is extended according to the signedness of the
type (so that wi::to_widest can use the same encoding) while rtxes
have the awkward special case of BI, which can be zero-extended
rather than sign-extended.
In the PR, we computed a hash for a "normal" sign-extended wide_int
while the existing entries hashed wi::to_wide(tree). This gives
different results for unsigned types that have the top bit set.
The patch fixes that by hashing the canonical sign-extended form even
if the raw encoding happens to be different.

The recursive_init_error class is defined in a header, with an inline
constructor, but the definition of the vtable and destructor are not
exported from the shared library. With -fkeep-inline-functions the
constructor gets emitted in user code, and requires the (non-exported)
vtable. This fails to link.
As far as I can tell, the recursive_init_error class definition was
moved into <cxxabi.h> so it could be documented with Doxygen, not for
any technical reason. But now it's there (and documented), somebody
could be relying on it, by catching that type and possibly performing
derived-to-base conversions to the std::exception base class. So the
conservative fix is to leave the class definition in the header but make
the constructor non-inline. This still allows the type to be caught and
still defines its base class. User code can no longer construct objects
of that type, but that's not something we need to support.

DCE tries to delete dead stores to local data and also tries to insert

/* If this is a store into a variable that is being optimized away,
add a debug bind stmt if possible. */
if (MAY_HAVE_DEBUG_BIND_STMTS
&& gimple_assign_single_p (stmt)
&& is_gimple_val (gimple_assign_rhs1 (stmt)))
{

gdebug *note

}
}
But this doesn't help for things like "print *ptr" when ptr points
to the local variable (tests Og-dce-1.c and Og-dce-2.c). It can
also introduce wrong debug info for earlier references (second test
in Og-dce-3.c) or make earlier references unavailable (first test
in Og-dce-3.c).
So for -Og I think it'd be better not to delete any stmts with
vdefs for now. This also means that we can avoid the potentially
expensive vop walks (which already have a cut-off, but still).
The patch also fixes the Og failures in gcc.dg/guality/pr54970.c

This patch stops gimple and rtl DSE from running by default at -Og.
The idea is both to improve compile time and to stop us from deleting
stores that we can't track in debug info.
We could rein this back in future for stores to local variables
with is_gimple_reg_type, but at the moment we don't have any
infrastructure for switching between binds to specific values
and binds to evolving memory locations. Even then, location
tracking only works for direct references to the variables, and doesn't
for example help with printing dereferenced pointers (see the next patch
in the series for an example).
I'm also not sure that DSE is important enough for -Og to justify the
compile time cost -- especially in the case of RTL DSE, which is pretty
expensive.

There isn't a 1:1 mapping from SVE intrinsics to SVE instructions,
but the intrinsics are still close enough to the instructions for
there to be a specific preferred sequence (or sometimes choice of
preferred sequences) for a given combination of operands. Sometimes
these sequences will be one instruction, sometimes they'll be several.
I therefore wanted a convenient way of matching the exact assembly
implementation of a given function. It's possible to do that using
single scan-assembler lines, but:
(a) they become hard to read for multiline matches
(b) the PASS/FAIL lines tend to be overly long
(c) it's useful to have a single place that skips over uninteresting
lines, such as entry block labels and .cfi_* directives, without
being overly broad
This patch therefore adds a new check-function-bodies dg-final test
that looks for specially-formatted comments. As a demo, the patch
converts the SVE vec_init tests to use the new harness instead of
scan-assembler.
The regexps in parse_function_bodies are fairly general, but might
still need to be extended in future for targets like Darwin or AIX.

more cases of a VEC_DUPLICATE of another vector. Duplicating
any fixed-length vector is fine, and duplicating a variable-length
vector is OK as long as that vector is also a duplicate of a

Other cases fell through to:

When gcc is configured using --with-cpu=<cpu>, the specified cpu
effectively becomes a default -mcpu=<cpu> passed to gcc. This then
affects the cpu passed to gas via ASM_CPU_SPEC. If gcc is not
configured using --with-cpu then the cpu passed to gas is that given
by ASM_DEFAULT_SPEC, which currently does not match the default flags
selected in default64.h. This patch makes ASM_DEFAULT_SPEC agree with
TARGET_DEFAULT flags.
rs6000/default64.h appears in three places in config.gcc, the first
one immediately followed by rs6000/freebsd64.h in $tm_file, and the
other two immediately followed by rs6000/linux64.h. To be able to
define ASM_DEFAULT_SPEC in rs6000/default64.h we don't want to
redefine in the other two files. rs6000/freebsd64.h is easy since
that file is always preceded by rs6000/default64.h, but
rs6000/linux64.h can appear without rs6000/default64.h (a
powerpc*-linux config where the default is -m32). In that case we
will have TARGET_DEFAULT flags of 0 (from rs6000/sysv4.h) and want to
use -mppc without -m64 and -mppc64 with -m64. This can be done by
using the rs6000/rtems.h ASM_DEFAULT_SPEC in rs6000/sysv4.h, a change
that won't affect sysv4 configurations where -m64 is invalid.
The patch also introduces ASM_DEFAULT_EXTRA for the altivec variant
targets so as to enable -maltivec by default.

This test is failing with older cpus because the included header needs both
altivec and vsx to be enabled to succeed in compiling. Without this (if these
are not defaults for the cpu) there are errors like:
In file included from ... x86intrin.h:41,
from ... bmi2-bzhi64-1a.c:6:
... xmmintrin.h: In function '_mm_loadu_ps':
... xmmintrin.h:122:11:
error: incompatible types when returning type 'int' but '__m128' {aka '__vector(4) float'} was expected
<snip>
... xmmintrin.h: In function '_mm_cvtps_pi32':
... xmmintrin.h:996:3:
error: use of 'long long' in AltiVec types is invalid without '-mvsx'
<snip>
Fixed by adding -maltivec -mvsx to the options.

and vsx.

Darwin's "size" command has a different header line, reflecting the Mach-O
section naming conventions. This causes tests using the command to fail
because scanasm.exp expects and checks specific layout of the header line.
