The pattern:

;; <su>q<addsub>

(define_insn "aarch64_<su_optab><optab><mode>"
  [(set (match_operand:VSDQ_I 0 "register_operand" "=w")
	(BINQOPS:VSDQ_I (match_operand:VSDQ_I 1 "register_operand" "w")
			  (match_operand:VSDQ_I 2 "register_operand" "w")))]
  "TARGET_SIMD"
  "<su_optab><optab>\\t%<v>0<Vmtype>, %<v>1<Vmtype>, %<v>2<Vmtype>"
  [(set_attr "type" "neon_<optab><q>")]
)

meant that we overloaded "optab" to be "qadd" for both SQADD and
UQADD.  Most other "optab" entries are instead the full optab name,
which for these patterns would be "ssadd" and "usadd" respectively.
(Unfortunately, the optabs don't extend to vectors yet, something
that would be good to fix in GCC 11.)

This patch therefore does what the comment implies and uses
q<addsub> to distinguish qadd and qsub instead.

pass_return_slot::execute has:

	      /* Ignore internal functions without direct optabs,
		 those are expanded specially and aggregate_value_p
		 on their result might result in undesirable warnings
		 with some backends.  */
	      && (!gimple_call_internal_p (stmt)

	      && aggregate_value_p (TREE_TYPE (gimple_call_lhs (stmt)),

But what the comment says applies to directly-mapped internal functions
too, since they're only used if the target supports them without a
libcall.

This was triggering an ICE on the attached testcase.  The svld3 call
is folded to an IFN_LOAD_LANES, which returns an array of vectors with
VNx48QImode.  Since no such return type can exist in C, the target hook
was complaining about an unexpected use of SVE modes.  (And we want to
keep asserting for that, so that we don't accidentally define an ABI for
an unexpected corner case.)

One problem with adding an N-bit vector extension to an existing
architecture is to decide how N-bit vectors should be passed to
functions and returned from functions.  Allowing all N-bit vector
types to be passed in registers breaks backwards compatibility,
since N-bit vectors could be used (and emulated) before the vector
extension was added.  But always passing N-bit vectors on the
stack would be inefficient for things like vector libm functions.

For SVE we took the compromise position of predefining new SVE vector
types that are distinct from all existing vector types, including
GNU-style vectors.  The new types are passed and returned in an
efficient way while existing vector types are passed and returned
in the traditional way.  In the right circumstances, the two types
are inter-convertible.

The SVE types are created using:

      vectype = build_distinct_type_copy (vectype);
      SET_TYPE_STRUCTURAL_EQUALITY (vectype);
      TYPE_ARTIFICIAL (vectype) = 1;

The C frontend maintains this distinction, using VIEW_CONVERT_EXPR
to convert from one type to the other.  However, the distinction can
be lost during gimple, which treats two vector types with the same
mode, number of elements, and element type as equivalent.  And for
most targets that's the right thing to do.

This patch therefore adds a hook that lets the target choose
whether such vector types are indeed equivalent.

Note that the new tests fail for -mabi=ilp32 in the same way as other
ACLE-based tests.  I'm still planning to fix that as a follow-on.

This prevents the vtables and RTTI from being emitted in every object
file that uses memory_resource and monotonic_buffer_resource.

Objects compiled by GCC 9.1 or 9.2 will contain inline definitions of
the destructors, vtable and RTTI, but this is harmless. The inline
definitions have identical effects to the ones that are now defined in
libstdc++.so so it doesn't matter if the inline ones are used instead of
calling the symbols exported from the runtime library.

with using them, so we are deprecating them.  There doesn't seem to be an
ABI break from dropping them so this patch modifies gcc to stop creating
them.  I'm using an ifdef for now in case a problem turns up and the code

When recursing into a directory, any errors that occur while removing a
directory entry are ignored, because the subsequent increment of the
directory iterator clears the error_code object.

This fixes that bug by checking the result of each recursive operation
before incrementing. This is a change in observable behaviour, because
previously other directory entries would still be removed even if one
(or more) couldn't be removed due to errors. Now the operation stops on
the first error, which is what the code intended to do all along. The
standard doesn't specify what happens in this case (because the order
that the entries are processed is unspecified anyway).

It also improves the error reporting so that the name of the file that
could not be removed is included in the filesystem_error exception. This
is done by introducing a new helper type for reporting errors with
additional context and a new function that uses that type. Then the
overload of std::filesystem::remove_all that throws an exception can use
the new function to ensure any exception contains the additional
information.

For std::experimental::filesystem::remove_all just fix the bug where
errors are ignored.
