bfd:
* elf32-xtensa.c (check_loop_aligned): Fix reversed check for
undefined opcode. Clean up assertions.
(narrow_instruction, widen_instruction): Remove "do_it" parameters.
Factor most of the code into separate functions....
(can_narrow_instruction, can_widen_instruction): New.
(prev_instr_is_a_loop): New.
(compute_ebb_proposed_actions): Combine error handling code for
decode errors. Replace call to insn_decode_len with inline code.
Use can_narrow_instruction and can_widen_instruction. Handle errors
from call to xtensa_opcode_is_loop.
(relax_section): Adjust calls to narrow_instruction and
widen_instruction.
gas:
* config/tc-xtensa.c (is_direct_call_opcode, is_branch_jmp_to_next,
xg_assemble_vliw_tokens, xtensa_mark_narrow_branches,
xtensa_fix_short_loop_frags, is_local_forward_loop, relax_frag_immed):
Handle errors from calls to xtensa_opcode_is_* functions.
