Subject: [PATCH] 	* config/tc-mips.c (RDATA_SECTION_NAME): Define. 
 (macro): Correct M_LI_SS SVR4_PIC/EMBEDDED_PIC case.  After M_LI_D 	or
 M_L_DOB or label dob, force a new frag to avoid getting 	confused in
 tc_gen_reloc. 	(mips_ip): Use RDATA_SECTION_NAME, not .rdata. 
 (s_change_sec): Likewise.
