    • Fix ICE with #line directive (PR c/89410) · 200a8e1a 
      PR c/89410 reports various issues with #line directives with very
large numbers; one of them is an ICE inside diagnostic-show-locus.c
when emitting a diagnostic at line 0xffffffff.

The issue is that the arithmetic in layout::calculate_line_spans to
determine if two line spans are sufficiently close to consolidate
was using the unsigned 32-bit linenum_type, which was overflowing
when comparing the line for the expanded location with those of
the location range (all on line 0xffffffff), leading to it
erroneously adding two spans for the same line, leading to an
assertion failure.

This patch fixes the ICE by generalizing the use of long long in
line-map.h's comparison function for linenum_type into a new
linenum_arith_t typedef, and using it here.

Doing so uncovered a second problem: the loop to print the lines
within the line_span for this case is infinite: looping from
0xfffffff upwards, overflowing to 0, and then never becoming
greater than 0xfffffff.  The patch fixes this by using linenum_arith_t
there also.

gcc/ChangeLog:
	PR c/89410
	* diagnostic-show-locus.c (layout::calculate_line_spans): Use
	linenum_arith_t when determining if two adjacent line spans are
	close enough to merge.

	lines within each line_span.

    • PR c++/87513 - 'sorry' mangling PMF template-id. · 60067b87 
      Here build_offset_ref calls build_qualified_name to make a SCOPE_REF because
the dependent template arguments make type_dependent_expression_p (member)
true.  We could probably work hard to prevent this, but it doesn't seem
necessary, and it's easy to fix write_expression to handle the result.

    • [rs6000] fix PR 88100, range check for vec_splat_{su}{8,16,32} · e86ae7ba 
      GCC revision 259524 implemented range check for the vec_splat_{su}{8,16,32}
builtins.  However, as a consequence of the implementation, the range check
is not done correctly for the expected vspltis[bhw] instructions.  The result
is that we may not get a valid error message if the valid range of the data
is exceeded.

Although the input of the function prototype of vec_splat_{su}{8,16,32} is
const int, the actual data usage range is limited to the data range of 5 bits
signed.  We should limit the int_cst.val[0] data to the 5 bit signed data range
without any modification in the input arg0 parameter.  However, the sext_hwi
function intercepts the data of TREE_INT_CST_LOW (arg0) as size bits in the
sext_hwi (TREE_INT_CST_LOW (arg0), size) statement.  This will cause some of
the excess data to fall within the range of 5 bits signed, so that the correct
diagnostic information cannot be generated, we need to remove the sext_hwi to
ensure that the input data has not been modified.

This patch fix range check for the vec_splat_s[8,16,32] builtins.  The argument
must be a 5-bit const int as specified for the vspltis[bhw] instructions.

    • PR c++/88368 - wrong 'use of deleted function' · 9d35a27a 
      Since my patch for 81359 allowed us to signal failure on return from
maybe_instantiate_noexcept, we no longer need to turn an error into
noexcept(false).  We also need to handle NSDMI instantiation errors under

get_defaulted_eh_spec to restore that context.
