[gensupport] PR 91255: Do not error out immediately on set_attr_alternative with define_subst
I'm trying to add a define_subst use in the arm backend but am getting many build errors complaining about:
`set_attr_alternative' is unsupported by `define_subst'
Looking at the gensupport.c code it iterates over all define_insns and errors if any of them have set_attr_alternative.
The usecase I'm targetting doesn't involve patterns with set_attr_alternative, so I would like to make the define_subst handling
more robust to only error out if the define_subst is actually attempted on a set_attr_alternative.
This patch produces the error only if the set_attr_alternative attr matches the subst name.
This allows a build of the arm backend with a define_subst usage to succeed.

i386: Separate costs of pseudo registers from hard registers
processor_costs has costs of RTL expressions with pseudo registers and
and costs of hard register moves:
1. Costs of RTL expressions are used to generate the most efficient RTL
operations with pseudo registers.
2. Costs of hard register moves are used by register allocator to
decide how to allocate and move hard registers.
Since relative costs of pseudo register load and store versus pseudo
register moves in RTL expressions can be different from relative costs
of hard registers, we should separate costs of RTL expressions with
pseudo registers from costs of hard registers so that register allocator
and RTL expressions can be improved independently.
This patch moves costs of hard register moves to the new hard_register
field and duplicates costs of moves which are also used for costs of RTL
expressions.

PR libstdc++/91456 make INVOKE<R> work with uncopyable prvalues
In C++17 a function can return a prvalue of a type that cannot be moved
or copied. The current implementation of std::is_invocable_r uses
std::is_convertible to test the conversion to R required by INVOKE<R>.
That fails for non-copyable prvalues, because std::is_convertible is
defined in terms of std::declval which uses std::add_rvalue_reference.
In C++17 conversion from R to R involves no copies and so is not the
same as conversion from R&& to R.
This commit changes std::is_invocable_r to check the conversion without
using std::is_convertible.
std::function also contains a similar check using std::is_convertible,
which can be fixed by simply reusing std::is_invocable_r (but because
std::is_invocable_r is not defined for C++11 it uses the underlying
std::__is_invocable_impl trait directly).

[AArch64] Optimise aarch64_add_offset for SVE VL constants
aarch64_add_offset contains code to decompose all SVE VL-based constants

This patch improves that fallback by reusing expand_mult if

[AArch64] Rework SVE INC/DEC handling
The scalar addition patterns allowed all the VL constants that
ADDVL and ADDPL allow, but wrote the instructions as INC or DEC
if possible (i.e. adding or subtracting a number of elements * [1, 16]
when the source and target registers the same). That works for the
cases that the autovectoriser needs, but there are a few constants
that INC and DEC can handle but ADDPL and ADDVL can't. E.g.:
inch x0, all, mul #9
is not a multiple of the number of bytes in an SVE register, and so
can't use ADDVL. It represents 36 times the number of bytes in an
SVE predicate, putting it outside the range of ADDPL.
This patch therefore adds separate alternatives for INC and DEC,
tied to a new Uai constraint. It also adds an explicit "scalar"
or "vector" to the function names, to avoid a clash with the
existing support for vector INC and DEC.

[AArch64] Rework SVE REV[BHW] patterns
The current SVE REV patterns follow the AArch64 scheme, in which
UNSPEC_REV<NN> reverses elements within an <NN>-bit granule.
E.g. UNSPEC_REV64 on VNx8HI reverses the four 16-bit elements
within each 64-bit granule.
The native SVE scheme is the other way around: UNSPEC_REV64 is seen
as an operation on 64-bit elements, with REVB swapping bytes within
the elements, REVH swapping halfwords, and so on. This fits SVE more
naturally because the operation can then be predicated per <NN>-bit
granule/element.
Making the patterns use the Advanced SIMD scheme was more natural
when all we cared about were permutes, since we could then use
the source and target of the permute in their original modes.
However, the ACLE does need patterns that follow the native scheme,
treating them as operations on integer elements. This patch defines
the patterns that way instead and updates the existing uses to match.
This also brings in a couple of helper routines from the ACLE branch.

Add support for conditional shifts
This patch adds support for IFN_COND shifts left and shifts right.
This is mostly mechanical, but since we try to handle conditional
operations in the same way as unconditional operations in match.pd,
we need to support IFN_COND shifts by scalars as well as vectors.
E.g.:
IFN_COND_SHL (cond, a, { 1, 1, ... }, fallback)
and:
IFN_COND_SHL (cond, a, 1, fallback)
are the same operation, with:
(for shiftrotate (lrotate rrotate lshift rshift)
...
/* Prefer vector1 << scalar to vector1 << vector2
if vector2 is uniform. */
(for vec (VECTOR_CST CONSTRUCTOR)
(simplify
(shiftrotate @0 vec@1)
(with { tree tem = uniform_vector_p (@1); }
(if (tem)
(shiftrotate @0 { tem; }))))))
preferring the latter. The patch copes with this by extending
create_convert_operand_from to handle scalar-to-vector conversions.

Add generic support for noinit attribute.
Similar to what already exists for TI msp430 or in TI compilers for
arm, this patch adds support for the "noinit" attribute.
It is convenient for embedded targets where the user wants to keep the
value of some data when the program is restarted: such variables are
not zero-initialized. It is mostly a helper/shortcut to placing
variables in a dedicated section.
It's probably desirable to add the following chunk to the GNU linker:
diff --git a/ld/emulparams/armelf.sh b/ld/emulparams/armelf.sh
index
272a8bc..
9555cec 100644

so that the noinit section has the "NOLOAD" flag.
I added a testcase if gcc.c-torture/execute, gated by the new noinit

[Ada] Compiler speedup with inlining across units
This change is aimed at speeding up the inlining across units done by
the Ada compiler when -gnatn is specified and in the presence of units
instantiating a lot of generic packages.
The current implementation is as follows: when a generic package is
being instantiated, the compiler scans its spec for the presence of
subprograms with an aspect/pragma Inline and, upon finding one,
schedules the instantiation of its body. That's not very efficient
because the compiler doesn't know yet if one of those inlined
subprograms will eventually be called from the main unit.
The new implementation arranges for the compiler to instantiate the body
on demand, i.e. when it encounters a call to one of the inlined
subprograms. That's still not optimal because, at this point, the
compiler has not yet computed whether the call itself is reachable from
the main unit (it will do this computation at the very end of the
processing, just before sending the inlined units to the code generator)
but that's nevertheless a net progress.
The patch also enhances the -gnatd.j option to make it output the list
of instances "inlined" this way. The following package is a simple
example:
with Q;
procedure P is
begin
Q.Proc;
end;
package Q is
procedure Proc;
pragma Inline (Proc);
end Q;
with G;
package body Q is
package My_G is new G (1);
procedure Proc is
Val : constant Integer := My_G.Func;
begin
if Val /= 1 then
raise Program_Error;
end if;
end;
end Q;
generic
Value : Integer;
package G is
function Func return Integer;
pragma Inline (Func);
end G;
package body G is
function Func return Integer is
