Use ira_setup_alts for conflict detection
make_early_clobber_and_input_conflicts records allocno conflicts
between inputs and earlyclobber outputs. It (rightly) avoids
doing this for inputs that are explicitly allowed to match the
output due to matching constraints.
The problem is that whether this matching is allowed varies
between alternatives. At the moment the code avoids adding
a clobber if *any* enabled alternative allows the match,
even if some other operand makes that alternative impossible.
The specific instance of this for SVE is that some alternatives
allow matched earlyclobbers when a third operand X is constant zero.
We should avoid adding conflicts when X really is constant zero,
but should ignore the match if X is nonzero or nonconstant.
ira_setup_alts can already filter these alternatives out for us,
so all we need to do is use it in process_bb_node_lives. The
preferred_alternatives variable is only used for this earlyclobber
detection, so no other check should be affected.
With the previous patch to check the reject weight in ira_setup_alts,
this has the effect of ignoring expensive alternatives if we have
other valid alternatives with zero cost. It seems reasonable to base
the heuristic on only the alternatives that we'd actually like to use,
but if this ends up being too aggressive, we could instead make the new
reject behaviour conditional and only use it for add_insn_allocno_copies.

Allow earlyclobbers in ira_get_dup_out_num
ira_get_dup_out_num punted on operands that are matched to
earlyclobber outputs:
/* It is better ignore an alternative with early clobber. */
else if (*str == '&')
goto fail;
But I'm not sure why this is the right thing to do. At this stage
we've established that *all* alternatives of interest require the
input to match the output, so
(a) the earlyclobber can only affect other operands and
(b) not tying the registers is bound to introduce a move
The code was part of the initial commit and so isn't obviously
related to a specific testcase. Also, I can imagine LRA makes
a much better job of this situation than reload did. (Certainly
SVE uses matched earlyclobbers extensively and I haven't seen any
problems.)
In case this turns out to regress something important: the main
case that matters for SVE is the one in which all alternatives
are earlyclobber.

Make ira_get_dup_out_num handle more cases
SVE has a prefix instruction (MOVPRFX) that acts as a move but is
designed to be easily fusible with the following instruction. The SVE
port therefore has lots of patterns with constraints of the form:
A: operand 0: =w,?w
...
operand n: 0, w
where the first alternative is a single instruction and the second
alternative uses MOVPRFX.
Ideally we want operand n to be allocated to the same register as
operand 0 in this case.
add_insn_allocno_copies is the main IRA routine that deals with tied
operands. It is (rightly) very conservative, and only handles cases in
which we're confident about saving a full move. So for a pattern like:
B: operand 0: =w,w
...
operand n: 0,w
we don't (and shouldn't) assume that tying operands 0 and n would
save the cost of a move.
But in A, the second alternative has a ? marker, which makes it more
expensive than the first alternative by a full reload. So I think for
copy elision we should ignore the untied operand n in the second
alternative of A.
One approach would be to add '*' markers to each pattern and make
ira_get_dup_out_num honour them. But I think the rule applies on
first principles, so marking with '*' shouldn't be necessary.
This patch instead makes ira_get_dup_out_num ignore expensive
alternatives if there are other alternatives that match exactly.
The cheapest way of doing that seemed to be to take expensive
alternatives out of consideration in ira_setup_alts, which provides
a bitmask of alternatives and has all the information available.
add_insn_allocno_copies is the only current user of ira_setup_alts,
so no other code should be affected.
If all available alternatives are disparaged or need a reload,
there's not much we can do to cut them down at this stage,
since it's hard to predict which operands will be reloaded and
which registers will need to be spilled.
An interesting case is patterns like this msp430 one:
;; Alternatives 2 and 3 are to handle cases generated by reload.
(define_insn "subqi3"
[(set (match_operand:QI 0 "nonimmediate_operand" "=rYs, rm, &?r, ?&r")
(minus:QI (match_operand:QI 1 "general_operand" "0, 0, !r, !i")
(match_operand:QI 2 "general_operand" " riYs, rmi, rmi, r")))]
""
"@
SUB.B\t%2, %0
SUB%X0.B\t%2, %0
MOV%X0.B\t%1, %0 { SUB%X0.B\t%2, %0
MOV%X0.B\t%1, %0 { SUB%X0.B\t%2, %0"
)
Here alternative 3 is significantly more expensive then alternative 0
(reject costs 0 and 606 respectively). But if operand 1 is an integer
constant, we'll still use alternative 3 if operand 2 is an allocated
register. On the other hand, if operand 1 is an integer constant but
operand 2 is spilled to memory, we'll move the constant into a register
and use the first alternative.
So in this case, if operand 1 is a register, we should consider
only the first two alternatives and thus try to tie operand 1
to operand 0 (which we didn't do previously). If operand 1 is a
constant integer, we should consider at least alternatives 0, 1 and 3.
We could exclude alternative 2, but I don't have any evidence that
that's useful.

[PATCH, Ada] Push -shared-libgcc where needed.
Gnatlink has code that checks for duplicate '-shared-libgcc’ switches (but not

targets that default to static linking, provided '-shared-libgcc' is not present.
For targets that should use a shared libgcc we need the same process to be

shared flag implicitly.
So this adds the complementary set of tests for the shared case and pushes
the shared flag as needed. As a minor tidy-up there’s no need push duplicates

The patch does not alter any of the platform defaults for static/shared libgcc,

PR c++/70462 - unnecessary base ctor variant with final.
As pointed out in the PR, we don't need base 'tor variants for a final
class, since it can never be a base. I tried also dropping complete
variants for abstract classes, but that runs into ABI compatibility problems
with older releases that refer to those symbols.
* optimize.c (populate_clone_array): Skip base variant if
CLASSTYPE_FINAL.
(maybe_clone_body): We don't need an alias if we are only defining
one clone.

libgo/testsuite: ignore symbols with a leading dot in symtogo
On AIX, a function has two symbols, a text symbol (with a leading dot)
and a data one (without it).
As the tests must be run only once, only the data symbol can be used to
retrieve the final go symbol. Therefore, all symbols beginning with a dot
are ignored by symtogo.
