This fixes unintended clobbering of SSA_NAME_DEF_STMT of the
cloned/inlined from SSA name during IPA parameter manipulation
of call stmt LHSs.  gimple_call_set_lhs adjusts SSA_NAME_DEF_STMT
of the lhs to the stmt being modified but when
ipa_param_body_adjustments::modify_call_stmt is called the
cloning/inlining process has not yet remapped the stmts operands
to the copy variants but they are still original.

	PR ipa/100513
	* ipa-param-manipulation.c
	(ipa_param_body_adjustments::modify_call_stmt): Avoid
	altering SSA_NAME_DEF_STMT by adjusting the calls LHS
	via gimple_call_lhs_ptr.

The PR shows us attaching REG_CFA_ADJUST_CFA notes to stack pointer
adjustments emitted in cmse_nonsecure_call_inline_register_clear (when
-march=armv8.1-m.main). However, the stack pointer is not guaranteed to
be the CFA reg. If we're at -O0 or we have -fno-omit-frame-pointer, then
the frame pointer will be used as the CFA reg, and these notes on the sp
adjustments will lead to ICEs in dwarf2out_frame_debug_adjust_cfa.

This patch avoids emitting these notes if the current function has a
frame pointer.

This patch removes the duplication between the mul_laneq<mode>3
and the older mul-lane patterns.  The older patterns were previously
divided into two based on whether the indexed operand had the same mode
as the other operands or whether it had the opposite length from the
other operands (64-bit vs. 128-bit).  However, it seemed easier to
divide them instead based on whether the indexed operand was 64-bit or
128-bit, since that maps directly to the arm_neon.h “q” conventions.

Also, it looks like the older patterns were missing cases for
V8HF<->V4HF combinations, which meant that vmul_laneq_f16 and
vmulq_lane_f16 didn't produce single instructions.

There was a typo in the V2SF entry for VCONQ, but in practice
no patterns were using that entry until now.

The test passes for both endiannesses, but endianness does change
the mapping between regexps and functions.

When a taskloop doesn't have any iterations, GOMP_taskloop* takes an early
return, doesn't create any tasks and more importantly, doesn't create
a taskgroup and doesn't register task reductions.  But, the code emitted
in the callers assumes task reductions have been registered and performs
the reduction handling and task reduction unregistration.  The pointer
to the task reduction private variables is reused, on input it is the alignment
and only on output it is the pointer, so in the case taskloop with no iterations
the caller attempts to dereference the alignment value as if it was a pointer
and crashes.  We could in the early returns register the task reductions
only to have them looped over and unregistered in the caller, but I think
it is better to tell the caller there is nothing to task reduce and bypass
all that.

This patch teaches rs6000_density_test to only care about the vector
version cost calculation and early return when calculating the single
scalar iteration cost.

Bootstrapped/regtested on powerpc64le-linux-gnu P9.

gcc/ChangeLog:

	* config/rs6000/rs6000.c (struct rs6000_cost_data): New member

	(rs6000_density_test): Early return if costing_for_scalar is true.
	(rs6000_init_cost): Init costing_for_scalar of rs6000_cost_data.

rs6000 port function rs6000_density_test wants to differentiate the
current cost model is for the scalar version of a loop or block, or
the vector version.  As Richi suggested, this patch introduces one
new parameter costing_for_scalar to init_cost hook to pass down this
information explicitly.

This unconditionally enables the maybe_save_operator_binding mechanism
for all function templates, so that when resolving a dependent operator
expression from a function template we ignore later-declared
namespace-scope bindings that weren't visible at template definition
time.  This patch additionally makes the mechanism apply to dependent
comma and compound-assignment operator expressions.

Note that this doesn't fix the testcases in PR83035 or PR99692 because
there the dependent operator expressions aren't at function scope.  I'm
not sure how adapt this mechanism for these testcases, since although
we'll in both testcases have a TEMPLATE_DECL to associate the lookup
result with, at instantiation time we won't have an appropriate binding
level to push to.

This PR is about CTAD but the underlying problems are more general;
CTAD is a good trigger for them because of the necessary substitution
into constraints that deduction guide generation entails.

In the testcase below, when generating the implicit deduction guide for
the constrained constructor template for A, we substitute the generic
flattening map 'tsubst_args' into the constructor's constraints.  During
this substitution, tsubst_pack_expansion returns a rebuilt pack
expansion for sizeof...(xs), but doesn't carry over the
PACK_EXPANSION_LOCAL_P (and PACK_EXPANSION_SIZEOF_P) flag from the
original tree to the rebuilt one.  The flag is otherwise unset on the
original tree but gets set for the rebuilt tree from make_pack_expansion
since at_function_scope_p() is true (we're inside main).  This leads to
a crash during satisfaction when substituting into the pack expansion
because we don't have local_specializations set up (and it'd be set up
for us if PACK_EXPANSION_LOCAL_P is unset)

Similarly, tsubst_constraint needs to set cp_unevaluated so that the
substitution performed therein doesn't rely on local_specializations.
This avoids a crash during CTAD for C below.

This has been tentatively approved by LWG. The deleter from a unique_ptr
can be moved into the shared_ptr (at least, since LWG 2802). This uses
std::forward<_Del>(__r.get_deleter()) not std::move(__r.get_deleter())
because we don't want to convert the deleter to an rvalue when _Del is
an lvalue reference type.

This also adds a missing is_move_constructible_v<D> constraint to the
shared_ptr(unique_ptr<Y, D>&&) constructor, which is inherited from the
shared_ptr(Y*, D) constructor due to the use of "equivalent to" in the
specified effects.

Code that has heavy register pressure on Altivec registers can suffer from
over-aggressive scheduling during sched1, which then leads to increased
register spill. This is due to the fact that registers that prefer
ALTIVEC_REGS are currently assigned an allocno class of VSX_REGS. This then
misleads the scheduler to think there are 64 regs available, when in reality
there are only 32 Altivec regs. This patch fixes the problem by assigning an
allocno class of ALTIVEC_REGS and adding ALTIVEC_REGS as a pressure class.

arm.h has had this error message since 1997, and was never updated to
take softfp into account. Anyway, it seems it was useful long ago, but
it is no longer needed since option parsing has been improved:
-mfloat-abi is handled via arm.opt and updates the var_float_abi
variable. So, the last instance of -mfloat-abi= on the command line
wins.

This patch just removes this error message, thus enabling many more
tests to pass on arm-eabi:

2021-05-10  Christophe Lyon  <christophe.lyon@linaro.org>

	gcc/
	* config/arm/arm.h (CPP_SPEC): Remove error message about
	-mfloat-abi.

The node and edge summaries defined in ipa-prop.h are probably the
oldest in GCC and so it happened that they are the only ones using
macros to look them up and create them.  With Honza and Martin we
agreed it is ugly and the macros should be removed and the ipa-prop
summaries should be accessed like all the other ones but somehow I
never got to it until now.

The patch is mostly mechanical.  Because the lookup machinery was much
simpler in the old times (something like the fast summaries we have
today), a lot of code queried for the summary multiple times for no
good reasons and I fixed that in places where it was easy.

Also, before we switched to hash based summaries, new summary pointers
had to be obtained whenever the underlying array could be reallocated
because of new cgraph nodes/edges.  This is no longer necessary and so
I removed the instances which I found.

Both kinds of these non-mechanical changes should be specifically called
out in the ChangeLog.

I also removed the IS_VALID_JUMP_FUNC_INDEX macro because it not used
anywhere.

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.

GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
dg-options directive prevents running these tests with different modes
such as -std=c++17 or -std=gnu++20.
