mhm, yes that is misleading. I'll prepare a patch to revert this.
Let me have a look if there were other such CAN_HAVE_LOCATION_P changes
that we'd want to revert.

Sorry for that!
I'd revert the hunk above and the one in gcc-rich-location.cc
(maybe_range_label_for_tree_type_mismatch::get_text), please see
attached. Bootstrap running, ok for trunk if it passes?

thanks,

Subject: [PATCH] c++, analyzer: Expand CAN_HAVE_LOCATION_P macro.

r14-985-gca2007a9bb3074 used the collapsed macro definition
CAN_HAVE_LOCATION_P in gcc-rich-location.cc and r14-977-g8861c80733da5c
in c++'s build_cplus_array_type ().
However, although otherwise correct, the usage of CAN_HAVE_LOCATION_P
in these two spots is misleading, so this patch reverts aforementioned
two hunks.

gcc/cp/ChangeLog:

	* tree.cc (build_cplus_array_type): Revert using the macro
	CAN_HAVE_LOCATION_P.

gcc/ChangeLog:

	* gcc-rich-location.cc (maybe_range_label_for_tree_type_mismatch::get_text):
	Revert using the macro CAN_HAVE_LOCATION_P.
