2001-05-09Correct and expand handling of `movm' instruction, and registerJim Blandy3-35/+101
saves in general. * config/mn10300/tm-mn10300.h (D0_REGNUM, A0_REGNUM, MDRQ_REGNUM, MCRH_REGNUM, MCRL_REGNUM, MCVF_REGNUM): New definitions. (enum movm_register_bits): New enum. * mn10300-tdep.c (set_movm_offsets): Use symbolic names for the bits, not hex literals. Handle the `other', `exreg0', and `exother' bits. Correct handling of `exreg1': it saves r4, r5, r6, and r7, not r2, r3, r4, and r5. (saved_regs_size): New function. (mn10300_frame_chain, mn10300_frame_saved_pc): Use it, instead of computing the same thing inline, incorrectly.
2001-05-09* mn10300-tdep.c (mn10300_gdbarch_init): We do have aJim Blandy2-1/+5
dummy_breakpoint_offset; it's zero.
2001-05-09* mn10300-tdep.c (mn10300_pop_frame): Split the mn10300-specificJim Blandy3-28/+40
stuff out into mn10300_pop_frame_regular, and use generic_pop_current_frame. This lets us share code, and also makes this function's prototype match that expected by gdbarch. Make this function static. (mn10300_pop_frame_regular): New function. (mn10300_gdbarch_init): Register mn10300_pop_frame as the gdbarch's pop_frame method. * config/mn10300/tm-mn10300.h (POP_FRAME): Delete definition. (mn10300_pop_frame): Delete declaration.
2001-05-09* mn10300-tdep.c (mn10300_saved_pc_after_call,Jim Blandy2-13/+24
mn10300_extract_return_value, mn10300_extract_struct_value_address, mn10300_store_return_value, mn10300_use_struct_convention, mn10300_breakpoint_from_pc, mn10300_frame_chain, mn10300_skip_prologue, mn10300_push_arguments, mn10300_push_return_address, mn10300_store_struct_return, mn10300_frame_saved_pc, mn10300_init_extra_frame_info, mn10300_frame_init_saved_regs): Make these functions static; they should only be visible to the outside world as gdbarch methods.
2001-05-09* config/mn10300/tm-mn10300.h (mn10300_find_callers_reg): DeleteJim Blandy2-2/+3
unused declaration.
2001-05-09* mn10300-tdep.c (mn10300_gdbarch_init): Put the gdbarch methodsJim Blandy2-18/+27
in some rational order.
2001-05-09* mn10300-tdep.c (mn10300_gdbarch_init): Rather than usingJim Blandy2-1/+4
generic_pc_in_call_dummy, use pc_in_call_dummy_at_entry_point.
2001-05-09Use gdbarch for most target parameters for the MN10300, ratherJim Blandy3-105/+84
than the tm-*.h file. * config/mn10300/tm-mn10300.h (MAX_REGISTER_VIRTUAL_SIZE, REGISTER_BYTES, FP_REGNUM, BREAKPOINT_FROM_PC, FUNCTION_START_OFFSET, DECR_PC_AFTER_BREAK, INNER_THAN, SAVED_PC_AFTER_CALL, INIT_EXTRA_FRAME_INFO, FRAME_INIT_SAVED_REGS, FRAME_CHAIN, FRAME_CHAIN_VALID, FRAME_SAVED_PC, EXTRACT_RETURN_VALUE, EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE, STORE_STRUCT_RETURN, SKIP_PROLOGUE, FRAME_ARGS_SKIP, FRAME_ARGS_ADDRESS, FRAME_LOCALS_ADDRESS, FRAME_NUM_ARGS, POP_FRAME, USE_GENERIC_DUMMY_FRAMES, CALL_DUMMY, CALL_DUMMY_START_OFFSET, CALL_DUMMY_BREAKPOINT_OFFSET, CALL_DUMMY_LOCATION, FIX_CALL_DUMMY, CALL_DUMMY_ADDRESS, TARGET_READ_FP, PUSH_RETURN_ADDRESS, PUSH_DUMMY_FRAME, SAVE_DUMMY_FRAME_TOS, PUSH_ARGUMENTS, PC_IN_CALL_DUMMY, REG_STRUCT_HAS_ADDR, USE_STRUCT_CONVENTION, GET_SAVED_REGISTER): Delete definitions. We register gdbarch methods for these now. (struct frame_info, struct type, struct value): Delete forward declarations of these types; they're no longer necessary, since we don't have function declarations here any more. * mn10300-tdep.c: #include "arch-utils.h", to get declarations for some default gdbarch methods. (mn10300_store_struct_return): Return void, as expected by gdbarch. (mn10300_init_extra_frame_info): Take initial `fromleaf' argument, as expected by gdbarch. (mn10300_frame_init_saved_regs): Provide dummy definition for this, as required by gdbarch. (mn10300_gdbarch_init): Add mn10300_call_dummy_words, as expected by gdbarch. Register gdbarch methods or values for all the stuff removed from tm-10300.h, listed above.
