Their contents are kept in + `registers', an array of bytes. This is done by + `fetch_inferior_registers'. `read_register', etc., just look + there. Writing a register works through + `store_inferior_registers' which writes one or all registers + from `registers' back to the inferior. + + A register now can have a "raw" data format and a "virtual" + data format, which may require conversion or even be different sizes. + The conversion can be different for different registers. + For example, the 68000 cpu registers need no conversion + and both raw and virtual size is 4, but the 68881 floating point + registers have raw size 12 (for extended fmt) and virtual size 8 + (for double). Macros in the m- file such as REGISTER_BYTES, + REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and + REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things. + + `read_register' and `write_register' are usable only on registers + which hold an int and need no conversion (raw fmt = virtual fmt). + For other registers, `read_register_bytes' is used, or + `read_relative_register_raw_bytes'. + + * m-sun3.h: Define the 68881 fp registers. + Know how to recognize insns that save them. + Make dummy frames save them. + + * core.c (read_register, write_registers): Functions deleted. + * findvar.c (read_register, write_registers): New functions, + not the same as the old ones of the same name. + + * findvar.c (supply_register): Function used by + fetch_inferior_registers, etc., to install the register + values fetched from the inferior. + + * findvar.c (read_register_bytes, write_register_bytes): + Read spec'd number of bytes from the byte-array `registers'. + + * findvar.c (read_relative_register_raw_bytes): + Replaces old function `read_relative_register'; accepts + address of where to store the contents; # bytes stored is size + of the specified register in raw format. + + * findvar.c (value_of_register, read_var_value): + Convert register values and values of register variables + from raw format to virtual format. + + * findvar.c (locate_var_value): Like `read_var_value' but + returns value for variable's address. + + * value.h: Add new field VALUE_REGNO to each value. It holds + register number to control virtual-to-raw conversion + for assignments to the value. + + * valops.c (value_assign): Convert data from virtual to raw format + if value came from a register variable. + Use read_register_bytes and write_register_bytes. + + + * infcmd.c (continue_command): Subtract 1 from arg + before setting breakpoint's ignore-count. + + * infcmd.c (jump_command): Query if spec'd line is outside + of the current function. + + * infcmd.c (finish_command): Now finish the selected frame, + and no arg required. + + * infcmd.c (set_environment_command): Allow space to separate + varname and value. + + * infcmd.c (registers_info): Print both raw and virtual data + format if they differ. Allow register name as arg. + Ask for a Newline each 16 registers. + + * inflow.c (kill_inferior): call mark_breakpoints_out. + * inflow.c ({fetch,store}_inferior_registers for Sun): + Get the fp registers and store them in right places in + `registers'. + * inflow.c ({read,write}_inferior_register): Deleted. + + * infrun.c (wait_for_inferior): Single-stepping is not considered + to have hit a breakpoint unless the pc before the step matches the + address of the breakpoint. Necessary on machines where + breakpoints leave the pc incremented. + + If shell gets SIGSEGV, pass the signal silently to it. + + * m68k-pinsn.c, m68k-opcode.h: + Add the 68881 instructions. New operand codes `F', `I', `s' + and `k' are needed for them. New place codes `78tcik'. + NEXTBYTE now skips a word but fetches just a byte. + Explicit sign-extension removed from NEXTBYTE and NEXTWORD. + NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined. + Various changes to implement the new operand and place codes. + print_index changed because displacement-size codes for + word and long displacement were interchanged. + + * m68k-pinsn.c (convert_{from,to}_68881): Functions added + to support REGISTER_CONVERT_TO_{RAW,VIRTUAL} on 68000. + + * main.c (main): Move around calls to setjmp. + * main.c (define_command, document_command): + Accept a from_tty argument instead of calling input_from_terminal_p. + + * printcmd.c (address_info): Print info on class and address + of a specified symbol. For register symbols, gives name of register. + + * printcmd.c (print_command): Remember explicitly whether + `make_cleanup' was called. + + * printcmd.c (print_frame_args): Know how arg-addresses vary with + data type on big-endian machines. + + * source.c (directory_command): Detect `:' in arg and reject it. + Free the old directory-path.
