Subject: 	* elf32-mips.c (_bfd_mips_elf_relocate_section): Handle R_MIPS_26
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5a44662b54e8ca902fa85726853b753107346023;p=binutils-gdb.git

	* elf32-mips.c (_bfd_mips_elf_relocate_section): Handle R_MIPS_26
	and R_MIPS16_26 relocations correctly when relocating.
	(_bfd_mips_elf_check_relocs): Don't assume that R_MIPS_CALL_HI16
	and R_MIPS_CALL_LO16 are for global symbols.
