Subject: 	* objdump.c (objdump_print_value): New static function.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c5ba27591accfa8f8ff03d6216e746b7476cb135;p=binutils-gdb.git

	* objdump.c (objdump_print_value): New static function.
	(objdump_print_address): Use it.  If we need the right section for
	the symbol, and we can't find it, print an offset from the section
	rather than using a symbol from some other section.
PR 8251.
