Subject: 	* gdbtypes.c (fill_in_vptr_fieldno): Don't ignore the first
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edf67bd18137953e9258f07a3474052e595a7524;p=binutils-gdb.git

	* gdbtypes.c (fill_in_vptr_fieldno): Don't ignore the first
	baseclass--we don't always inherit its virtual function table
	pointer.
