Subject: 	* elf32-mips.c (_bfd_mips_elf_final_write_processing): Handle
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1cfe12f298b76b8c6c78a394d2a050b5f0b17dd4;p=binutils-gdb.git

	* elf32-mips.c (_bfd_mips_elf_final_write_processing): Handle
	SHT_MIPS_LIBLIST, SHT_MIPS_CONTENT, SHT_MIPS_SYMBOL_LIB, and
	SHT_MIPS_EVENTS sections.
	(_bfd_mips_elf_section_from_shdr): Handle SHT_MIPS_IFACE,
	SHT_MIPS_CONTENT, SHT_MIPS_SYMBOL_LIB, and SHT_MIPS_EVENTS
	sections.
	(_bfd_mips_elf_fake_sections): Likewise.
