[Ada] Skip entity name qualification in GNATprove mode
GNATprove was using the qualification of names for entities with local
homonyms in the same scope, requiring the use of a suffix to
differentiate them. This caused problems for correctly identifying
primitive equality operators. This case is now handled like the rest of
entities in GNATprove, by instead updating Unique_Name to append the
suffix on-the-fly where needed.

[x86] Tweak testcases for PR82361
gcc/testsuite/gcc.target/i386/pr82361-[12].c check whether we
can optimise away a 32-to-64-bit zero extension of a 32-bit
division or modulus result. Currently this fails for the modulus
part of f1 and f2 in pr82361-1.c:
/* FIXME: We are still not able to optimize the modulo in f1/f2, only manage
one. */
/* { dg-final { scan-assembler-times "movl\t%edx" 2 } } */
pr82361-2.c instead expects no failures:
/* Ditto %edx to %rdx zero extensions. */
/* { dg-final { scan-assembler-not "movl\t%edx, %edx" } } */
But we actually get the same zero-extensions for f1 and f2 in pr82361-2.c.
The reason they don't trigger a failure is that the RA allocates the
asm input for "d" to %rdi rather than %rdx, so we have:
movl %rdx, %rdi
instead of:
movl %rdx, %rdx
For the tests to work as expected, I think they have to force "c" and
"d" to be %rax and %rdx respectively. We then see the same failure in
pr82361-2.c as for pr82361-1.c (but doubled, due to the 8-bit division
path).

Since FDPIC currently supports arm and thumb-2 modes only, these tests
fail because they enforce an architecture version that doesn't match
these restrictions.
This patch introduces new values for the arm_arch effective-target
(v4t_thumb, v5t_thumb, v5te_thumb, v6_thumb, v6k_thumb, v6z_thumb) as
needed, and adds them to the relevant tests. In addition, it adds
v4t_arm, v5t_arm, v5te_arm, v6_arm, v6k_arm and v6z_arm to avoid
skipping some tests when GCC is configured to generate Thumb code by
default.
It also adds the corresponding non-thumb effective-target to the tests
that were missing it.
The existing v4t, v5t, v5te, v6 v6k and v6z effective-targets now force
-mfloat-abi=softfp since these thumb-1 targets do not support
hard-float anyway.
Finally, the patch removes the special case to detect the presence of
-marm in the flags, since it makes atomic_loaddi tests unsupported:
since the flags in question also include -march, the combination is
supported, while -marm alone is not if GCC is configured to target an

Function Double_Divide computes the division of its parameters
(X / (Y*Z)) in a way that avoids overflows on signed integers, except in
two specific cases, when X = -2**63, abs(Y) = abs(Z) = 1 (leading to an
overflow in -To_Int(Qu)) and when X = -2**63 and Y*Z is large enough
that Qu=0 and so the remainder Ru=2**63 (leading to an overflow in

This fix avoids the overflow by applying "-" on the unsigned value
before the conversion to signed integer.
The issue cannot manifest as an overflow check failure in our runtime,
as overflow checks are suppressed by using pragma Suppress at the start
of the file. Assuming a machine implements wraparound semantics here,
the result was correct even with the suppressed overflow.

PR c++/30277 - int-width bit-field promotion.
Here, if cp_perform_integral_promotions saw that the TREE_TYPE of a
bit-field reference was the same as the type it promotes to, it didn't do
anything. But then decay_conversion saw that the bit-field reference was
unchanged, and converted it to its declared type. So I needed to add
something to make it clear that promotion has been done. But then the 33819
change caused trouble by looking through the NOP_EXPR I just added. This
was the wrong fix for that bug; I've now fixed that better by recognizing in
cp_perform_integral_promotions that we won't promote a bit-field larger than
32 bits, so we should use the declared type.

Fix conversions for built-in operator overloading candidates.
While working on C++20 operator<=>, I noticed that build_new_op_1 was doing
too much conversion when a built-in candidate was selected; the standard
says it should only perform user-defined conversions, and then leave the
normal operator semantics to handle any standard conversions. This is
important for operator<=> because a comparison of two different unscoped
enums is ill-formed; if we promote the enums to int here, cp_build_binary_op
never gets to see the original operand types, so we can't give the error.

Consider doloop IV in IVOPTs
For the targets supporting low-overhead loops, IVOPTs has to take care of
the loops which will probably be transformed in RTL doloop optimization,
to try to make selected IV candidate set optimal. The process of doloop
support includes:
1) Analyze the current loop will be transformed to doloop or not, find and
mark its compare type IV use as doloop use (iv_group field doloop_p), and
set flag doloop_use_p of ivopts_data to notify subsequent processings on
doloop. See analyze_and_mark_doloop_use and its callees for the details.
The target hook predict_doloop_p can be used for target specific checks.
2) Add one doloop dedicated IV cand {(may_be_zero ? 1 : (niter + 1)), +, -1},
set flag doloop_p of iv_cand, step cost is set as zero and no extra cost
like biv. For cost determination between doloop IV cand and IV use, the
target hooks doloop_cost_for_generic and doloop_cost_for_address are
provided to add on extra costs for generic type and address type IV use.
Zero cost is assigned to the pair between doloop IV cand and doloop IV
use, and bound zero is set for IV elimination.
3) With the cost setting in step 2), the current cost model based IV
selection algorithm will process as usual, pick up doloop dedicated IV if
profitable.
