gcc/testsuite/gcc.dg/cpp/ucs.c #include <limits.h>
and then crafts a definition of WCHAR_MAX depending
on __WCHAR_TYPE__.

The test fails in VxWorks configurations because WCHAR_MAX
is already exposed by the system limits.h.

The patch simply guards the tentative definition
by a check verifying if the macro is defined already, so
we're using the value exposed by limits.h in this case.

On Vxworks 7, includers of stdint.h (which we currently "provide")
need yvals.h to have been included ahead.

Instead of altering the common stdint-gcc.h with unpleasant
vxworks specific bits to do that, we arrange to provide stdint-gcc.h
on its own along with a stdint.h wrapper which preincludes yvals.h
on vx7 then includes stdint-gcc.h.

When build_dynamic_cast realizes that a dynamic_cast needs a run-time check, it
generates a call to __dynamic_cast -- see dyncast.cc in libsupc++ for its
definition.  The gist of my approach is to evaluate such a call at compile time.

	* constexpr.c (cxx_dynamic_cast_fn_p): New function.
	(extract_obj_from_addr_offset): New function.
	(get_component_with_type): New function.
	(cxx_eval_dynamic_cast_fn): New function.
	(cxx_eval_call_expression): Call cxx_eval_dynamic_cast_fn for a call
	to __dynamic_cast.
	(potential_constant_expression_1): Don't give up on
	cxx_dynamic_cast_fn_p.
	* rtti.c (build_dynamic_cast_1): When creating a call to
	__dynamic_cast, use the location of the original expression.

In this testcase we use an unmasked SVE loop with an Advanced SIMD
epilogue (because we don't yet support fully-masked downward loops).
The main loop uses a gather load for the strided access while the
epilogue loop builds the access from scalars instead.  In both cases
we gimplify expressions based on the DR_STEP and insert them in the
loop preheader.

The problem was that the gather load code didn't copy the DR_STEP before
gimplifying it, meaning that the epilogue loop tried to reuse a result
from the (non-dominating) main loop preheader.

It looks at first glance like there could be other instances of this too,
but this patch just deals with the gather/scatter case.

The EXTRACT_LAST_REDUCTION handling needs to generate a separate
comparison instruction that feeds the vector mask argument of the
IFN_EXTRACT_LAST call.  We weren't checking whether that comparison
was supported, leading to an ICE on the testcase.

gcc/
	* tree-vect-stmts.c (vectorizable_condition): For extract-last
	reductions, check that the target supports the required comparison
	operation.
