Hello.
This patch removes obsolete GO_IF_LEGITIMATE_ADDRESS macro from CRIS back
end in the GCC and introduces equivalent ARGET_LEGITIMATE_ADDRESS_P target
hook.
Regression tested on cris-axis-elf.
OK to install?
* config/cris/cris.c (reg_ok_for_base_p, reg_ok_for_index_p,
cris_constant_index_p, cris_base_p, cris_index_p,
cris_base_or_autoincr_p, cris_bdap_index_p, cris_biap_index_p,
cris_legitimate_address_p): New functions.
(TARGET_LEGITIMATE_ADDRESS_P): Define.
(cris_pic_symbol_type, cris_valid_pic_const): Change arguments type
from rtx to const_rtx.
(cris_print_operand_address, cris_address_cost,
cris_side_effect_mode_ok): Use
cris_constant_index_p, cris_base_p, cris_base_or_autoincr_p,
cris_biap_index_p and cris_bdap_index_p.
* config/cris/cris.h (CONSTANT_INDEX_P, BASE_P, BASE_OR_AUTOINCR_P,
BDAP_INDEX_P, BIAP_INDEX_P, GO_IF_LEGITIMATE_ADDRESS,
REG_OK_FOR_BASE_P, REG_OK_FOR_INDEX_P): Remove.
(EXTRA_CONSTRAINT_Q, EXTRA_CONSTRAINT_R, EXTRA_CONSTRAINT_T): Use
cris_constant_index_p, cris_base_p, cris_base_or_autoincr_p,
cris_biap_index_p and cris_bdap_index_p.
* config/cris/cris.md (moversideqi movemsideqi peephole2): Use
cris_base_p.
* config/cris/cris-protos.h (cris_constant_index_p, cris_base_p,
cris_base_or_autoincr_p, cris_bdap_index_p, cris_biap_index_p): New
