Subject: 	* elf32-m68k.c (elf_m68k_check_relocs): Cache reloc section in
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2ff124f9080f1f82c6d79174397c68d1542afde;p=binutils-gdb.git

	* elf32-m68k.c (elf_m68k_check_relocs): Cache reloc section in
	elf_section_data during processing of pc-relative and absolute
	relocations.
	(elf_m68k_relocate_section): Use the cached reloc section instead
	of computing it again.  Fix handling of visibility.  Don't modify
	addend when copying over a relocation into the output.
