X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4525c51ab02e6fdd29017d353e5decaceaeb1000;p=binutils-gdb.git

mach-o: remove name_len field.

bfd/
	* mach-o.h (bfd_mach_o_dylinker_command)
	(bfd_mach_o_dylib_command, bfd_mach_o_fvmlib_command): Remove
	name_len field.
	* mach-o.c (bfd_mach_o_read_dylinker, bfd_mach_o_read_dylib)
	(bfd_mach_o_read_fvmlib): Adjust after name_len removal.
