* config/m68hc11/larith.asm (__mulqi3): Fix multiplication of two negative numbers. (___subdi3, ___adddi3): Use x instead of y as index register. (__init_bss_section, __map_data_section): Optimize for 68HC12. (__memset, __memcpy): Likewise. (regs): Put the soft registers in bss for 68HC12. (abort): Use trap to abort for 68hc12. (__mulhi3, __mulhi32): Use emul for 68hc12. (__mulsi3): Avoid to use the tmp soft register for 68hc12. * config/m68hc11/m68hc11.h (LIMIT_RELOAD_CLASS): Don't define. * config/m68hc11/m68hc11-protos.h (limit_reload_class): Remove. * config/m68hc11/m68hc11.c (limit_reload_class): Remove. (m68hc11_override_options): Remove setting of flag_no_nonansi_builtin. Set 68HC12 min offset to -65536. (print_operand): Put parenthesis arround the operand if it refers to a symbol having the same name as a register. (m68hc11_z_replacement): When z register is replaced by its equivalent soft register, force the insn to be re-recognized. (m68hc11_check_z_replacement): Fix the test when destination is the index register and z dies in the insn. (m68hc11_reorg): Remove the REG_DEAD notes beforce recomputing them. * config/m68hc11/m68hc11.c (m68hc11_override_options): Initialize costs according to processor variant. (m68hc11_shift_cost): New function to compute shift costs. (m68hc11_rtx_costs): Define costs according to processor variant. (m6811_cost): Costs for 68HC11. (m6812_cost): Costs for 68HC12. (COSTS_N_INSNS): Remove. * config/m68hc11/m68hc11.h (RTX_COSTS): New. (DEFAULT_RTX_COSTS): Remove. (CONST_COSTS): Define costs according to OUTER_CODE. (processor_costs): New struct to define costs. (m68hc11_cost): Pointer to current costs. * config/m68hc11/m68hc11.md (*addhi3_68hc12): Fix generation and use m68hc11_notice_keep_cc when using leax/leay. (addhi3 split): Reject split if the insn is handled by leax/leay above. * config/m68hc11/m68hc11.c (m68hc11_split_move): For 68HC12 the push must be handled in a special way if the source operand uses sp as index register. (m68hc11_notice_keep_cc): New function. (m68hc11_gen_movhi): Use it when an insn changes a register but not the flags. (m68hc11_gen_movqi): Fix move for 68HC12. * config/m68hc11/m68hc11-protos.h (m68hc11_notice_keep_cc): Declare. * config/m68hc11/m68hc11.c (m68hc11_emit_libcall): Use LCT_CONST and don't pass operands[0] to emit_library_call_value. * config/m68hc11/m68hc11.md (tsthi_1): Use cpd for 68HC12. (zero_extendsi split): Simplify and use (zero_extendhi). (*addhi3): Remove 'w' constraint since stack pointer is handled by (addhi3_sp). (*ashlhi3_2): Operand 2 is clobbered use '+' for its constraint. (*ashlhi3, *ashrhi3, *lshrhi3): Likewise. (*ashrhi3_const): Fix shift by 7. (*lshrsi3_const16): Fix template. (call, call_value): Fix constraint and predicate. * config/m68hc11/m68hc11.md (X_REGNUM, D_REGNUM): New constant. (Y_REGNUM, SP_REGNUM, PC_REGNUM, A_REGNUM, B_REGNUM): Likewise. (CC_REGNUM): Likewise. (*unnamed splits): Use above constants instead of hard coded numbers. (*adcq, *subcq, *addsi_carry, *rotlqi3_with_carry): Likewise. (*rotlhi3_with_carry, *rotrhi3_with_carry): Likewise. (*return_16bit, *unnamed peepholes): Likewise. From-SVN: r41802 |
