New Revision: 179124
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=179124
Log:
* config/avr/avr.md (adjust_len): Add alternatives "tsthi",
"tstsi", "compare".
(*cmpqi_sign_extend): Use s8_operand.
(*cmphi, *cmpsi): Rewrite using avr_out_compare.
* config/avr/avr-protos.h (compare_diff_p, compare_eq_p): Remove
prototypes.
(out_tsthi, out_tstsi): Remove prototypes.
(avr_out_tsthi, avr_out_tstsi): New prototypes.
* config/avr/avr.c (out_tsthi, out_tstsi): Remove functions.
(avr_asm_len): Negative length now sets *plen to -length.
(compare_sign_p): Return bool instead of int.
(compare_diff_p, compare_eq_p): Ditto and make static.
(avr_out_tsthi): New function.
(avr_out_tstsi): New function.
(avr_out_compare): New function.
(adjust_insn_length): Handle ADJUST_LEN_TSTHI, ADJUST_LEN_TSTSI,
ADJUST_LEN_COMPARE.
