This patch adds a fix-it hint for the case where the member function
takes no parameters, suggesting the addition of the parentheses:

   14 |   return inst.length > 0.0;
      |          ~~~~~^~~~~~
      |                     ()

Support for this is not explicitly called for in OpenACC 2.6, but given that
GCC internally decomposes "wait (1, 2)" into "wait (1) wait (2)" (similar for
other clauses, too), it's reasonable to also support that syntax in the front
ends -- which happens to already be the case for C, C++, and easy enough to do

From backtrace.h for backtrace_create_state:

   Calling this function allocates resources that can not be freed.
   There is no backtrace_free_state function.  The state is used to
   cache information that is expensive to recompute.  Programs are
   expected to call this function at most once and to save the return
   value for all later calls to backtrace functions.

So instead of calling backtrace_create_state every time we wish to
show a backtrace, do it once and store the result in a static
variable.  libbacktrace allows multiple threads to access the state,
so no need to use TLS.

PR preprocessor/88257 reports an ICE on gcc.dg/format/pr78304.c
when compiled using g++:

void test (const char *msg)
{
  printf ("size: %" PRIu32 "\n", msg);
}

due to mismatching files (and line maps) between
linemap_resolve_location and expand_location_to_spelling_point
when PRIu32 is defined in a system header.

The root cause is that expand_location_to_spelling_point stops
unwinding locations when it reaches a system header, whereas
linemap_resolve_location can resolve into a system header,
which can lead to locations within get_substring_ranges_for_loc
getting out of sync, and using the wrong line map.

This patch fixes the issue by checking that the files are the
same.

	PR preprocessor/88257

This patch aims to prevent long sequences loading soft-float
constants.  For 32-bit, it makes sense to load values inline to a gpr
with lis, addi, but not so much for 64-bit where a 5 insn sequence
might be needed for each gpr.  For TFmode in particular, a 10 insn
sequence is reduced to 2 loads from memory plus 1 or 2 address setup
insns.

	* config/rs6000/predicates.md (easy_fp_constant): Avoid long
	dependent insn sequences.
	* config/rs6000/rs6000.c (num_insns_constant): Support long
	double constants.
	* config/rs6000/rs6000.md (mov<mode>_softfloat <FMOVE128>): Adjust
	length attribute.

This patch came about from investigating an ICE that appeared when I
was retesting an old half-baked patch of mine to rs6000_rtx_costs.
If a const_double is fed to rs6000_is_valid_and_mask and from there to
rs6000_is_valid_mask where INTVAL is used, gcc will ICE.

The num_insns_constant ICE was introduced with git commit f337168d97.
However, the code was buggy before that.  There was no point in
testing for a mask since the mask predicates only handle const_int.
In fact, I don't think the function ever handled floating point
constants that might match a load of minus one and mask.  It does now.
I've added a few comments regarding splitters so the next person
looking at this code can see how this works.

The patch also extracts code out of num_insns_constant that needed to
handle multiple gprs for DFmode constants in 32-bit mode, to a
function that handles multiple gprs a little more generally.  I don't
think there is any need for anything but the 32-bit DFmode case
currently, but this allows for possible future uses.  The
CONST_WIDE_INT case is also not used currently, and needed fixing.
Adding CONST_WIDE_INT_NUNITS - 1 only makes sense if the elements of
the array were being shifted into a register of size larger than the
element size (which is 64-bits).

	* config/rs6000/rs6000.c (num_insns_constant_gpr): Renamed from
	num_insns_constant_wide.  Make static.  Revise comment.
	(num_insns_constant_multi): New function.
	(num_insns_constant): Formatting.  Correct CONST_WIDE_INT
	calculation.  Simplify and extract code common to both
	CONST_INT and CONST_DOUBLE.  Add gcc_unreachable for unhandled
	const_double modes.
	* config/rs6000/rs6000-protos.h (num_insns_const_wide): Delete.
