510: Thu Jan 22 00:31:03 1987 Richard M. Stallman (rms at prep)
511:
512: * Version 2.0.
513:
514: * blockframe.c (get_pc_function_start):
515: Understand misc functions.
516:
517: * core.c (core_file_command):
518: Copy all register contents into the array `registers'
519: Save a.out header of executable file in core_aouthdr.
520: Print name of executable file that was running, if we know
521: where to find it.
522:
523: * core.c (exec_file_command):
524: Save a.out header in exec_aouthdr and file's mtime
525: in exec_mtime.
526:
527: * core.c (validate_files): Check that core file's a.out hdr
528: matches exec file's.
529:
530: * New handling of registers:
531: Now all registers are fetched once when the program stops or
532: when a core file is selected. Their contents are kept in
533: `registers', an array of bytes. This is done by
534: `fetch_inferior_registers'. `read_register', etc., just look
535: there. Writing a register works through
536: `store_inferior_registers' which writes one or all registers
537: from `registers' back to the inferior.
538:
539: A register now can have a "raw" data format and a "virtual"
540: data format, which may require conversion or even be different sizes.
541: The conversion can be different for different registers.
542: For example, the 68000 cpu registers need no conversion
543: and both raw and virtual size is 4, but the 68881 floating point
544: registers have raw size 12 (for extended fmt) and virtual size 8
545: (for double). Macros in the m- file such as REGISTER_BYTES,
546: REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and
547: REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things.
548:
549: `read_register' and `write_register' are usable only on registers
550: which hold an int and need no conversion (raw fmt = virtual fmt).
551: For other registers, `read_register_bytes' is used, or
552: `read_relative_register_raw_bytes'.
553:
554: * m-sun3.h: Define the 68881 fp registers.
555: Know how to recognize insns that save them.
556: Make dummy frames save them.
557:
558: * core.c (read_register, write_registers): Functions deleted.
559: * findvar.c (read_register, write_registers): New functions,
560: not the same as the old ones of the same name.
561:
562: * findvar.c (supply_register): Function used by
563: fetch_inferior_registers, etc., to install the register
564: values fetched from the inferior.
565:
566: * findvar.c (read_register_bytes, write_register_bytes):
567: Read spec'd number of bytes from the byte-array `registers'.
568:
569: * findvar.c (read_relative_register_raw_bytes):
570: Replaces old function `read_relative_register'; accepts
571: address of where to store the contents; # bytes stored is size
572: of the specified register in raw format.
573:
574: * findvar.c (value_of_register, read_var_value):
575: Convert register values and values of register variables
576: from raw format to virtual format.
577:
578: * findvar.c (locate_var_value): Like `read_var_value' but
579: returns value for variable's address.
580:
581: * value.h: Add new field VALUE_REGNO to each value. It holds
582: register number to control virtual-to-raw conversion
583: for assignments to the value.
584:
585: * valops.c (value_assign): Convert data from virtual to raw format
586: if value came from a register variable.
587: Use read_register_bytes and write_register_bytes.
588:
589:
590: * infcmd.c (continue_command): Subtract 1 from arg
591: before setting breakpoint's ignore-count.

611:
612: * infrun.c (wait_for_inferior): Single-stepping is not considered
613: to have hit a breakpoint unless the pc before the step matches the
614: address of the breakpoint. Necessary on machines where
615: breakpoints leave the pc incremented.
616:
617: If shell gets SIGSEGV, pass the signal silently to it.
618:
619: * m68k-pinsn.c, m68k-opcode.h:
620: Add the 68881 instructions. New operand codes `F', `I', `s'
621: and `k' are needed for them. New place codes `78tcik'.
622: NEXTBYTE now skips a word but fetches just a byte.
623: Explicit sign-extension removed from NEXTBYTE and NEXTWORD.
624: NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined.
625: Various changes to implement the new operand and place codes.
626: print_index changed because displacement-size codes for
627: word and long displacement were interchanged.
628:
629: * m68k-pinsn.c (convert_{from,to}_68881): Functions added
630: to support REGISTER_CONVERT_TO_{RAW,VIRTUAL} on 68000.

641:
642: * printcmd.c (print_frame_args): Know how arg-addresses vary with
643: data type on big-endian machines.
644:
645: * source.c (directory_command): Detect `:' in arg and reject it.

650:
651: * source.c (find_source_lines): Compare source mtime against
652: `exec_mtime' and warn if source is newer.
653:
654: * source.c (line_info): No arg means use last line listed
655: or line following last one this command was used on.
656: If from tty, clear out argument so Return is like `i li' without
657: arg.
658:
659: * stack.c (frame_info): Print addresses registers are saved at.
660:
661: * stack.c (return_command): When asking for confirmation, give
662: name of function that will be made to return.
663:
664: * valops.c (call_function): If function type is
665: pointer-to-function, dereference it to compute return type.
666: If pointer-to-object, assume function returns int.
667: If char, assume that the value's address is the function address
668: (because it's a misc functon). If int, the value itself is the
669: function address.
670:
671: * dbxread.c (compare_symbols): Sort register symbols
672: before all others.
673:
674: * eval.c (evaluate_subexp_for_address): New function like
675: `evaluate_subexp' but returns a value for the address where
676: the subexpression's value would be located.
677:
678: * eval.c (evaluate_subexp_for_sizeof): New function like

684:
685: * eval.c (evaluate_subexp): Use the three new functions above
686: when appropriate instead of calling self recursively.

727:
728: * symtab.c (decode_line_1):
729: If no symtabs, err mentioning `symbol-file' command rather than

792: select the frame that we get to.
793:
794: * dbxread.c (process_one_symbol): Store new `depth' field

857:
858: * dbxread.c (process_one_symbol): If N_LBRAC sym

870:
871: * valprint.c (type_print*):
872: SHOW < 0 now means abbreviate struct/union members
873: or enum values with `...'. SHOW now decremented on
874: each recursion in type_print_base. Several places
875: that used to check !show now check show <= 0.
876:

878: when printing typename inside parens or braces.
879:
880: * printcmd.c (print_command): If no value specified to print,

885: and now allows any expression, not just an integer address.
886: It now has same format as UNOP_CAST and works almost like it.
887: Each place that referred to it has been rewritten
888: starting with a copy of the code that handles UNOP_CAST.
889: Doc for `print' command changed for this.
890:

892: Free and zero out any line_charpos's saved in source symtabs.
893:
894: * breakpoint.c (condition_command):
895: Parse the condition in the environment of the code where the

897: before parsing, so code is rearranged.
898:
899: * dbxread.c (dbx_alloc_type):
900: New function given typenums returns the type for those typenums
901: or allocates a new, empty type for those typenums and returns it.
902:
903: * symtab.c (smash_type_to_{pointer,function}):
904: New functions modify an already-allocated type object
905: to be a pointer to or function returning some given type.
906:
907: * dbxread.c (read_type): Uses dbx_alloc_type in many cases.
908: Reading a pointer or function type now works by doing that,
909: then reading the value type or type pointed to, then smashing
910: it into the type already allocated. This makes some fwd refs win.
911: Likewise for structs and unions.
912:
913: * dbxread.c (read_struct_type): Now receives the type object
914: as args. Used to get typenums as args and look up the type
915: itself.

925: Sun Nov 16 14:59:07 1986 Richard M. Stallman (rms at prep)
926:
927: * values.c (value_field): Was adding in byte offset
928: before calling unpack_field_as_long, which itself
929: adds in the offset. Now pass addr of start of structure.
930:
931: * infrun.c (normal_stop): Clean up inferior_pid conditionals:
932: just return early if no inferior.
