opcodes:
* sh-opc.c (sh_table): Use A_DISP_PC / PCRELIMM_8BY2 for ldre & ldrs. stc GBR,@-<REG_N> is available for arch_sh1_up. Group parallel processing insn with identical mnemonics together. Make three-operand psha / pshl come first. gas: * config/tc-sh.c (get_operands): There's no third operand if the first operand is an immediate.
