* config/avr/avr-protos.h (avr_output_bld): New. (out_shift_with_cnt): Add t_len argument. * config/avr/avr.c (avr_num_arg_regs): Remove -mpack-args. (output_movqi, output_movhi, output_movsisf): Optimize loading any constant with exactly one bit set to NO_LD_REGS. (out_shift_with_cnt): Optimize output code for size or speed, depending on optimize_size. Handle small shift counts as well (if not hand-optimized in ?sh??i3_out). Shifts can be done with or without a scratch register, with help of __tmp_reg__ or __zero_reg__ if necessary. Add T_LEN argument to pass the length of TEMPLATE in words, return total insn length in *LEN. (ashlqi3_out, ashrqi3_out, lshrqi3_out): Change all calls to out_shift_with_cnt to work with the above change. (ashlhi3_out, ashlsi3_out, ashrhi3_out, ashrsi3_out, lshrhi3_out, lshrsi3_out): Likewise. Optimize more known shift count cases. Remove cases already well optimized in out_shift_with_cnt. (avr_output_bld): New function. * config/avr/avr.h (MASK_PACK_ARGS, TARGET_PACK_ARGS): Remove. (TARGET_SWITCHES): Remove -mpack-args backward compatibility. * config/avr/avr.md (*reload_inqi, *reload_inhi, *reload_insi): Add reload_completed to insn condition - only for peepholes. (ashlqi3, ashrqi3, lshrqi3): Correct insn length for shift counts in a register or memory. (ashlhi3, ashlsi3, ashrhi3, ashrsi3, lshrhi3, lshrsi3): Likewise. Do not require a scratch register. (*ashlhi3_const, *ashlsi3_const, *ashrhi3_const, *ashrsi3_const, *lshrhi3_const, *lshrsi3_const): New insns and matching peepholes. Optimize shifts by known count using a scratch register, but only if one is still available after register allocation. From-SVN: r36963 |
