PR91068 is a case in which we have (ignoring non-LRA alternatives):

  [(set (match_operand:SI 0 "register_operand" "=l,d?")
	(plus:SI (mult:SI (match_operand:SI 1 "register_operand" "d,d")
			  (match_operand:SI 2 "register_operand" "d,d"))
		 (match_operand:SI 3 "register_operand" "0,d")))
   (clobber (match_scratch:SI 4 "=X,l"))
   (clobber (match_scratch:SI 5 "=X,&d"))]

where the first alternative is one instruction but the second is two.
This is very similar to the case that my recent IRA patches were
supposed to help.  The crucial difference is that the cheap
alternative requires a single-register class while the expensive
alternative uses general registers.

This makes a difference when one of operand 0 or 3 can naturally be
allocated to LO but the other can't.  If IRA makes that allocation,
both alternatives require one reload of equal cost and so the first
alternative clearly wins.

However, if we say that tying operands 0 and 3 saves the cost of a full
move, then all other things being equal, IRA will prefer to allocate
both registers to the same GPR.  The registers will then naturally
fit the second alternative.

This has a more drastic effect in the MIPS case than it should because
using the GPR alternative is much more expensive there than it appears
to the RA.  But that's really a separate problem and something we were
able to live with before my IRA patch.

What makes tying less useful here is the fact that the tied register is
a single-register class.  I think in those circumstances it's better not
to use tied operands at all and instead use "l" for the inputs.
Allocating the input to LO, and allocating the output to LO, then depend
naturally on class costs.  If we decide to allocate at least one of them
to LO, we'll use the cheap alternative, otherwise we'll (correctly) use
the expensive alternative.  This effectively restores the situation
before my IRA patch, but this time making the preference on the input
register more explicit.

I originally wrote the patterns in the early days of IRA, and certainly
well before LRA.  I think they were largely influened by reload rather
than RA proper (see the comment above *mul_acc_si, which is all about
the reload behaviour).  LRA copes with the two-"l" case just fine.

The patch may well cause problems for -mno-lra, but I think we should
cull that option anyway.

This patch is part of a series that fixes ambiguous attribute
uses in .md files, i.e. cases in which attributes didn't use
<ITER:ATTR> to specify an iterator, and in which <ATTR> could
have different values depending on the iterator chosen.

The vx-builtins.md part changes the choice of <mode> from the
implicit <VFCMP:mode> to an explicit <VF_HW:mode> (i.e. from the
mode of the comparison result to the mode of the operands being
compared).  That seemed like the intended behaviour given later
patterns like vec_cmpeq<mode>_cc.

The use of BFP in the s390.md LNDFR pattern looks like a typo,
since the operand to (abs ...) has to have the same mode as the result.
The only effect before this series was to create some extra variants
that would never match, making it harmless apart from very minor code
bloat.

-#define HAVE_atomic_compare_and_swapt1hi_1 ((TARGET_HAVE_LDREX && TARGET_HAVE_MEMORY_BARRIER) && (TARGET_THUMB1))
-#define HAVE_atomic_compare_and_swapt1di_1 ((TARGET_HAVE_LDREX && TARGET_HAVE_MEMORY_BARRIER) && (TARGET_THUMB1))

+       && TARGET_HAVE_MEMORY_BARRIER) && (TARGET_THUMB1))

Because the inline versions of __exchange_and_add and __atomic_add are
also marked static, they cannot be used from templates or other inline
functions without ODR violations. This change gives them external
linkage, but adds the always_inline attribute.

    	* include/ext/atomicity.h [_GLIBCXX_ATOMIC_BUILTINS] (__atomic_add)
    	(__exchange_and_add): Replace static specifier with always_inline
    	attribute.
    	(__exchange_and_add_single, __atomic_add_single): Likewise.
    	(__exchange_and_add_dispatch, __atomic_add_dispatch): Likewise. Also
    	combine !__gthread_active_p() and !__GTHREADS branches.
