Subject: 	* readelf.c (dynamic_nent): New variable.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86dba8ee8a31d6d427240ce9b9629ab5e6aadf67;p=binutils-gdb.git

	* readelf.c (dynamic_nent): New variable.
	(get_32bit_dynamic_section): Set it.
	(get_64bit_dynamic_section): Here too.
	(process_dynamic_section): Use it instead of dynamic_size.
	(process_syminfo): Likewise.
