    • Testsuite: Turn off vect-epilogue-nomask for slp-rect-3 · 60178a32 
      Without epiloque no mask it would only try HI modes, but thanks to the
epiloques nomask It tries QI mode as well which succeeds.  The xfail
then generates an xpass since the condition on it checks for HI to SI
and not QI.

So I disabled the epiloque mask since it seems to violate the conditions
the test actually wanted to test for.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/slp-reduc-3.c: Turn off epilogue-nomask.

    • Handle C2x attributes in Objective-C. · 34b43828 
      When adding the initial support for C2x attributes, I deferred the
unbounded lookahead support required to support such attributes in
Objective-C (except for the changes to string literal handling, which
were the riskier piece of preparation for such lookahead support).
This patch adds that remaining ObjC support.

For C, the parser continues to work exactly as it did before.  For
ObjC, however, when checking for whether '[[' starts attributes, it
lexes however many tokens are needed to check for a matching ']]', but
in a raw mode that omits all the context-sensitive processing that
c_lex_with_flags normally does, so that that processing can be done
later when the right context-sensitive flags are set.  Those tokens
are saved in a separate raw_tokens vector in the parser, and normal
c_lex_one_token calls will get tokens from there and perform the
remaining processing on them, if any tokens are found there, so all
parsing not using the new interfaces gets the same tokens as it did
before.  (For C, this raw lexing never occurs and the vector of raw
tokens is always NULL.)

Bootstrapped with no regressions for x86_64-pc-linux-gnu.

gcc/c:
	* c-parser.c (struct c_parser): Add members raw_tokens and
	raw_tokens_used.
	(c_lex_one_token): Add argument raw.  Handle lexing raw tokens and
	using previously-lexed raw tokens.
	(c_parser_peek_nth_token_raw)
	(c_parser_check_balanced_raw_token_sequence): New functions.
	(c_parser_nth_token_starts_std_attributes): Use
	c_parser_check_balanced_raw_token_sequence for Objective-C.

	* objc.dg/attributes/gnu2x-attr-syntax-1.m: New test.

    • Implement P1814R0, CTAD for alias templates. · 1a291106 
      This patch implements C++20 class template argument deduction for alias
templates, which works by a moderately arcane transformation of the
deduction guides for the underlying class template.  When implementing it,
it seemed that I could simplify the rules in the draft a bit and get
essentially the same effect; I'll be emailing the committee to that effect
soon.
