* config/tc-xtensa.c (xtensa_j_opcode): New. (xg_instruction_matches_option_term): Handle "FREEREG" option. (xg_build_to_insn): Likewise. Update renamed tls_reloc reference. (md_begin): Initialize xtensa_j_opcode. (md_assemble): Update renamed tls_reloc reference. Handle "j.l". (xg_assemble_vliw_tokens): Save free_reg info in the frag. (tinsn_immed_from_frag): Get free_reg info back out of the frag. (vinsn_to_insnbuf): Update renamed tls_reloc references. Distinguish extra argument for "FREEREG" from extra TLS argument. * config/tc-xtensa.h (struct xtensa_frag_type): Add free_reg field. * config/xtensa-istack.h (struct tinsn_struct): Rename tls_reloc field to extra_arg. * config/xtensa-relax.c (widen_spec_list): Add rules to relax "j.l". (build_transition): Handle "FREEREG" operand. * config/xtensa-relax.h (enum op_type): Add OP_FREEREG. 2008-11-04 Bob Wilson <bob.wilson@acm.org> * gas/xtensa/all.exp: Run jlong test. * gas/xtensa/jlong.d: New. * gas/xtensa/jlong.s: New.
