47:
48: * dbxread.c: (define_symbol) store static functions ('f') in the

65: * findvar.c: (locate_var_value, read_var_value) got rid of checks
66: for LOC_BLOCK which called `lookup_function_type'. These checks
67: are no longer needed because of the change to dbxread.c.
68:
69: * infcmd.c: (finish_command) Now uses target_type instead of type
70: for functions, in keeping with the change to dbxread.c.
71:

93: `fliped')
94:
95: * m-pn.h, m-npl.h: added #define gould, since this is needed in
96: core.c.
97:
98: Tue Jun 14 04:07:50 1988 Pete TerMaat (pete at lucky-charms.ai.mit.edu)

137: that for a parm declared register the register comes before the parm.
138:
139: * defs.h: declare alloca.
140:
141: Fri May 20 15:02:50 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)

192: Fri Apr 15 01:01:40 1988 Chris Hanson (cph at kleph)
193:
194: * inflow.c [! TIOCGPGRP]: Do not call `setpgrp' for inferior.
195: Instead, disable SIGINT and SIGQUIT while the inferior is running.

200:

223:
224: Tue Apr 12 19:11:00 1988 Chris Hanson (cph at kleph)
225:
226: * stack.c (print_frame_info): When -fullname is given and
227: `identify_source_line' succeeds, do not print real pc even if it
228: differs from the start pc for the source line. This information
229: is not very useful and tends to screw up gdb-mode in emacs.
230:
231: Mon Apr 11 14:22:10 1988 Chris Hanson (cph at kleph)

238:
239: * inflow.c (store_inferior_register_1) [HP9K320]: Ignore `errno',

241: non-zero when writing fp7.
242:
243: Sat Apr 9 01:04:23 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
244:
245: * dbxread.c (symbol_file_command): Check stringtab size by doing `stat'
246: and, if it is ridiculous, complain and don't call alloca.
247: Don't discard existing symtab until after that check.
248:
249: Fri Apr 8 16:39:11 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
250:
251: * Makefile: Delete `-lg' entirely; not needed now that linking is done

255:
256: * m68k-opcode.h: Fix operand-string of fmovel insns.

276: Include wait.h
277: (remote_wait): Use the wait.h interface.
278:
279: * utils.c (quit): Need HAVE_TERMIO conditional. Also include param.h.

298: * dbxread.c (add_symbol_to_list, finish_block, read_enum_type):
299: Symbol-lists now hold up to 20 symbols in each `struct pending'

341: (symbol_file_command): These macros replace open code.
342:
343: * values.c (unpack_double): When fetching `double' from memory,
344: make it double-aligned, since some machines need that.

1094: Thu Jan 22 00:31:03 1987 Richard M. Stallman (rms at prep)
1095:
1096: * Version 2.0.
1097:
1098: * blockframe.c (get_pc_function_start):
1099: Understand misc functions.
1100:
1101: * core.c (core_file_command):
1102: Copy all register contents into the array `registers'
1103: Save a.out header of executable file in core_aouthdr.
1104: Print name of executable file that was running, if we know
1105: where to find it.

1108: Save a.out header in exec_aouthdr and file's mtime
1109: in exec_mtime.
1110:
1111: * core.c (validate_files): Check that core file's a.out hdr
1112: matches exec file's.
1113:
1114: * New handling of registers:
1115: Now all registers are fetched once when the program stops or
1116: when a core file is selected. Their contents are kept in
1117: `registers', an array of bytes. This is done by
1118: `fetch_inferior_registers'. `read_register', etc., just look
1119: there. Writing a register works through
1120: `store_inferior_registers' which writes one or all registers
1121: from `registers' back to the inferior.
1122:
1123: A register now can have a "raw" data format and a "virtual"
1124: data format, which may require conversion or even be different sizes.
1125: The conversion can be different for different registers.
1126: For example, the 68000 cpu registers need no conversion
1127: and both raw and virtual size is 4, but the 68881 floating point
1128: registers have raw size 12 (for extended fmt) and virtual size 8
1129: (for double). Macros in the m- file such as REGISTER_BYTES,
1130: REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and
1131: REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things.
1132:
1133: `read_register' and `write_register' are usable only on registers
1134: which hold an int and need no conversion (raw fmt = virtual fmt).
1135: For other registers, `read_register_bytes' is used, or
1136: `read_relative_register_raw_bytes'.
1137:
1138: * m-sun3.h: Define the 68881 fp registers.
1139: Know how to recognize insns that save them.
1140: Make dummy frames save them.
1141:
1142: * core.c (read_register, write_registers): Functions deleted.

1144: not the same as the old ones of the same name.
1145:
1146: * findvar.c (supply_register): Function used by
1147: fetch_inferior_registers, etc., to install the register
1148: values fetched from the inferior.
1149:
1150: * findvar.c (read_register_bytes, write_register_bytes):
1151: Read spec'd number of bytes from the byte-array `registers'.
1152:
1153: * findvar.c (read_relative_register_raw_bytes):
1154: Replaces old function `read_relative_register'; accepts
1155: address of where to store the contents; # bytes stored is size
1156: of the specified register in raw format.
1157:
1158: * findvar.c (value_of_register, read_var_value):
1159: Convert register values and values of register variables
1160: from raw format to virtual format.
1161:
1162: * findvar.c (locate_var_value): Like `read_var_value' but
1163: returns value for variable's address.
1164:
1165: * value.h: Add new field VALUE_REGNO to each value. It holds
1166: register number to control virtual-to-raw conversion
1167: for assignments to the value.
1168:
1169: * valops.c (value_assign): Convert data from virtual to raw format
1170: if value came from a register variable.
1171: Use read_register_bytes and write_register_bytes.
1172:
1173:

1195:
1196: * infrun.c (wait_for_inferior): Single-stepping is not considered
1197: to have hit a breakpoint unless the pc before the step matches the
1198: address of the breakpoint. Necessary on machines where
1199: breakpoints leave the pc incremented.
1200:
1201: If shell gets SIGSEGV, pass the signal silently to it.
1202:
1203: * m68k-pinsn.c, m68k-opcode.h:
1204: Add the 68881 instructions. New operand codes `F', `I', `s'
1205: and `k' are needed for them. New place codes `78tcik'.
1206: NEXTBYTE now skips a word but fetches just a byte.
1207: Explicit sign-extension removed from NEXTBYTE and NEXTWORD.
1208: NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined.
1209: Various changes to implement the new operand and place codes.
1210: print_index changed because displacement-size codes for
1211: word and long displacement were interchanged.
1212:
1213: * m68k-pinsn.c (convert_{from,to}_68881): Functions added

1231: dirname.
1232:
1233: * source.c (openp): Simplify `./' in specified name.
1234:
1235: * source.c (find_source_lines): Compare source mtime against
1236: `exec_mtime' and warn if source is newer.

1238: * source.c (line_info): No arg means use last line listed
1239: or line following last one this command was used on.
1240: If from tty, clear out argument so Return is like `i li' without
1241: arg.
1242:
1243: * stack.c (frame_info): Print addresses registers are saved at.
1244:
1245: * stack.c (return_command): When asking for confirmation, give
1246: name of function that will be made to return.
1247:
1248: * valops.c (call_function): If function type is
1249: pointer-to-function, dereference it to compute return type.
1250: If pointer-to-object, assume function returns int.
1251: If char, assume that the value's address is the function address
1252: (because it's a misc functon). If int, the value itself is the
1253: function address.
1254:
1255: * dbxread.c (compare_symbols): Sort register symbols
1256: before all others.
1257:
1258: * eval.c (evaluate_subexp_for_address): New function like

1527: Accept an instance code as arg and treat it as if it were
1528: part of the file name for distinguishing and finding entries.
1529:
1530: * dbxread.c (add_new_header_file, read_type):

1560: If get SIGSEGV with running_in_shell == 1, it is sh
1561: allocating memory. Pass the signal silently to the shell.
1562:
1563: * core.c (exec_file_command):
1564: data_{start,end} are adjusted unconditionally when an
1565: exec file is opened, so closing counter-adjustment is
1566: now unconditional as well.
1567:
1568: * printcmd.c (x_command):
1569: Don't erase the expression from the calling args
1570: if cllaed noninteractively (used to be clobbering
