[arm] PR target/83193: Do not print arch/cpu hints twice on invalid -march/-mcpu
Currently when handling an invalid -march or -mcpu option on a toolchain without an explicit --with-mode configuration
and compiling without an explicit -mthumb or -marm the arm specs end up calling arm_target_thumb_only to determine
the "thumbness" of the target, which involves parsing the architecture or cpu name. But the functions doing that
parsing also emit error messages and hints on invalid arguments. Later when we parse the architecture or cpu string to
as part of the canonicalisation process (arm_canon_arch_option) we end up emitting the errors again.
The solution in this patch is to silence the errors during the arm_target_thumb_only processing so that they are not emitted
twice. arm_canon_arch_option is guaranteed to run as well, so it can emit the errors and hints that it needs.
Bootstrapped and tested on arm-none-linux-gnueabihf.
Checked that we emit the arch/cpu hints for invalid -march/-mcpu options only once when no "thumbness" options were specified
during configuration or invocation.

[AArch64] PR target/84748: Mark *compare_cstore<mode>_insn as clobbering CC reg
In this wrong-code PR the combine pass ends up moving a CC-using instruction past a *compare_cstore<mode>_insn
insn_and_split. After reload the *compare_cstore<mode>_insn splitter ends up generating a SUBS instruction that
clobbers the condition flags, and things go bad.
The solution is simple, the *compare_cstore<mode>_insn pattern should specify that it clobbers the CC register
so that combine (or any other pass) does not assume that it can move CC-using patterns across it.
This patch does that and fixes the testcase.
The testcase FAILs on GCC 8 only, but the buggy pattern is in GCC 6 onwards, so we should backport this as
a latent bug fix after it's had some time to bake in trunk.

tree-if-conv.c: fix ICE seen with -fno-tree-forwprop (PR tree-optimization/84178)
PR tree-optimization/84178 reports a couple of source files that ICE inside
ifcvt when compiled with -03 -fno-tree-forwprop (trunk and gcc 7).
Both cases involve problems with ifcvt's per-BB gimplified predicates.
Testcase 1 fails this assertion within release_bb_predicate during cleanup:
283 if (flag_checking)
284 for (gimple_stmt_iterator i = gsi_start (stmts);
285 !gsi_end_p (i); gsi_next (&i))
286 gcc_assert (! gimple_use_ops (gsi_stmt (i)));
The testcase contains a division in the loop, which leads to
if_convertible_loop_p returning false (due to gimple_could_trap_p being true
for the division). This happens *after* the per-BB gimplified predicates
have been created in predicate_bbs (loop).
Hence tree_if_conversion bails out to "cleanup", but the gimplified predicates
exist and make use of SSA names; for example this conjunction for two BB
conditions:
_4 = h4.1_112 != 0;
_175 = (signed char) _117;
_176 = _175 >= 0;
_174 = _4 & _176;
is using SSA names.
This assertion was added in r236498 (aka
c3deca2519d97c55876869c57cf11ae1e5c6cf8b):

* gcc.dg/tree-ssa/ifc-cd.c: Adjust.
The following patch fixes this by adding a call to gimple_seq_discard
to release_bb_predicate. It also updates the assertion, so that
instead of asserting the stmts have no imm uses, instead assert that
they weren't added to a bb before discarding them (otherwise discarding
them would be a bug). We know this is the case because
insert_gimplified_predicates has:
/* Once the sequence is code generated, set it to NULL. */
set_bb_predicate_gimplified_stmts (bb, NULL);
but asserting it seems appropriate as a double-check.
The patch doesn't address the 2nd issue within PR tree-optimization/84178.

[LVU] reset view at function entry, omit views at line zero
Location views might be associated with locations that lack line
number information (line number zero), but since we omit .loc
directives that would have been issued with line number zero, we also
omit the symbolic view numbers that would have been issued at such
points.
Resetting views at function entry points address some of these issues,
and alleviate the huge chains of symbolic views that have burdened
assemblers since we disabled -ginternal-reset-location-views by
default, but other problems of undefined views remain when it's not
the whole function that lacks line number info, just parts of it.
So, when we encounter a request to output a view that may have been
referenced, but we decide to omit the .loc because the line is zero,
we will now omit the view as well, i.e., we will internally regard
that view as zero-numbered.

[C++] [PR84231] overload on cond_expr in template
A non-type-dependent COND_EXPR within a template is reconstructed with
the original operands, after one with non-dependent proxies is built to
determine its result type. This is problematic because the operands of
a COND_EXPR determined to be an rvalue may have been converted to denote
their rvalue nature. The reconstructed one, however, won't have such
conversions, so lvalue_kind may not recognize it as an rvalue, which may
lead to e.g. incorrect overload resolution decisions.
If we mistake such a COND_EXPR for an lvalue, overload resolution might
regard a conversion sequence that binds it to a non-const reference as
viable, and then select that over one that binds it to a const
reference. Only after template substitution would we rebuild the
COND_EXPR, realize it is an rvalue, and conclude the reference binding
is ill-formed, but at that point we'd have long discarded any alternate
candidates we could have used.
This patch modifies the logic that determines whether a
(non-type-dependent) COND_EXPR in a template is an lvalue, to rely on
its type, more specifically, on the presence of a REFERENCE_TYPE
wrapper. In order to avoid a type bootstrapping problem, the
REFERENCE_TYPE that wraps the type of some such COND_EXPRs is
introduced earlier, so that we don't have to test for lvalueness of
the expression using the very code that we wish to change.
