Subject: [PATCH] 	* config/tc-mips.c: If OBJ_ELF, include elf/mips.h. 
 (mips_regmask_frag): New static variable, if OBJ_ELF. 	(md_begin): If
 OBJ_ELF, create .reginfo section and set 	mips_regmask_frag to a frag. 
 (mips_elf_final_processing): New function, if OBJ_ELF.  Set 
 mips_regmask_frag to register mask information. 	* config/tc-mips.h
 (elf_tc_final_processing): New macro, defined 	if OBJ_ELF.
