1087 since gcc automatically includes it
1089 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1091 * procfs.c: Substantial (but incomplete) changes to support
1092 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1093 struct now has substructs like struct flt_ctl instead of
1094 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1095 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1096 still have the structs and multiple fds, but don't use the
1097 entire struct and the four fds all point to the same thing.
1098 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1099 procfs with reads/writes or use ioctl instead. We use
1100 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1101 multiple fds or not. PROC_NAME_FMT is split out into
1102 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1103 STATUS_PROC_NAME_FMT.
1105 (procfs_notice_signals): now a necessary wrapper around
1106 (notice_signals): which are the new guts for noticing signals
1107 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1108 determine whether or not to attempt to open the ctl_fd.
1109 (procfs_read_status): new local function, reads procfs status
1110 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1111 (procfs_write_pckill): new local function, writes a PCKILL
1112 (unconditionally_kill_inferior): remove signo since we now
1113 just call procfs_write_pckill().
1114 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1115 (proc_iterate_over_mappings): the whole function is ifdefed
1116 on UNIXWARE to keep things readable.
1118 Expanded the syscall_table to include new potential sysv4.2mp
1119 members. Note that all ifdefs of UNIXWARE should be eliminated
1120 if possible or renamed to describe what's being selected for a
1121 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1122 IRIX specific code now also checks it's not UNIXWARE.
1124 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1125 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1126 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1127 "/debug/%d" as PROC_NAME_FMT used to be
1129 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1131 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1133 * config/mn10300/tm-mn10300.h: Likewise.
1135 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1137 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1138 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1139 lousy out-of-date clone of remote.c.
1141 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1143 * remote.c: Fix problems realized while showering.
1144 * (hexnumlen): Add prototype. Use max, not min.
1145 * (remote_write_bytes remote_read_bytes): Fix max packet size
1146 calculations to properly account for packet overhead. Also handle
1147 (probably rare) case where remote_register_buf_size isn't set.
1149 * remote.c: Fix doc for `C' and `S' commands to indicate full
1151 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1153 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1154 Record size of response to fetch registers command, use this to
1155 limit size of memory read and write commands.
1156 * (push_remote_target): New function to make it possible to have
1157 another target switch to the remote target.
1158 * target.h: Add prototype for push_remote_target.
1159 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1160 for hosts which default to unsigned chars (such as SGI's).
1161 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1162 handled automatically in remote.c.
1164 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1166 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1167 find_pc_sect_function(), find_pc_sect_partial_function(): new
1168 functions for debugging overlays; pc without section is ambiguous.
1169 * breakpoint.[ch]: add section pointer to breakpoint struct;
1170 add section argument to check_duplicates(); check section as well
1171 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1172 breakpoint_thread_match(), bpstat_stop_status()];
1173 add section argument to describe_other_breakpoints();
1174 use INIT_SAL() macro to zero-out new sal structures;
1175 make resolve_sal_pc() fix up the sal's section as well as its pc;
1176 match on section + pc in clear_command() and delete_breakpoint();
1177 account for overlay sections in insert_breakpoints(),
1178 remove_breakpoint() and breakpoint_re_set_one();
1179 all this to support overlays where a PC is not unique.
1180 * exec.c: change xfer_memory() to handle overlay sections.
1181 * findvar.c: change read_var_value() to handle overlay sections.
1182 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1183 * infcmd.c: jump_command() warns against jumping into an overlay
1184 that's not in memory. Also use INIT_SAL() to initialize sals.
1185 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1186 overlay state information; Also use INIT_SAL() to init sals.
1187 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1188 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1189 memory read/writes in the range 600000 to a00000, and ff680000
1190 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1191 * maint.c: maintenance command "translate-address" supports overlays.
1192 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1193 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1194 this constitutes gdb's internal overlay mapping table. Add macro
1195 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1196 Add function find_pc_sect_section().
1197 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1198 modify address_info() with overlay smarts; add function sym_info()
1199 to support the INFO SYMBOL command (translate address to symbol(s));
1200 modify disassemble_command() to work on unmapped overlays.
1201 * source.c: use INIT_SAL() to initialize sals.
1202 * symfile.[ch]: change generic_load() to use section's LMA address
1203 instead of VMA address, for overlay sections.
1204 Add numerous functions for finding a PC's section / overlay,
1205 translating between VMA and LMA address ranges, determining if an
1206 overlay section is mapped, etc. Add several user commands for
1207 overlay debugging. Add support for a "generic" form of automatically
1208 reading overlay mapping info from the inferior (based on the default
1209 (simple) overlay manager which Cygnus provides as an example).
1210 * symtab.[ch]: add functions find_pc_sect_symtab(),
1211 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1212 for lookup; modify lookup_symbol and decode_line_1() to use them;
1213 modify find_function_start_sal() to account for overlay sections;
1214 add macro INIT_SAL() for initializing struct symtab_and_line.
1215 * target.c: fix a comment in the declaration of target_ops.
1217 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1219 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1230 the above functions.
1231 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1232 (mips_init_frame_pc): Declare.
1233 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1234 to decide if certain library function calls should be ignored.

1989 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1990 FP_REGISTER_BYTES to compute offsets into the saved frame,
1991 since it fails for SPARC targets configured without any
1992 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

2043 * target.c target.h (target_xfer_memory): Add bfd section to
2045 * (target_read_memory_section): New routine to read data from a
2047 * (target_memory_bfd_section): New global variable to pass bfd
2048 section in to targets.
2049 * valarith.c (value_add value_addr value_array): Preserve bfd
2050 section when computing new value.
2051 * value.h (struct value): Add bfd section to values.

2066 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2067 also removed code elsewhere that made use of RP_REGNUM.
2068 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2069 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2070 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2071 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
