Thu Apr 17 02:20:23 1997 Doug Evans <dje@canuck.cygnus.com>
* remote-sim.c (gdbsim_load): Update call to sim_load.
(gdbsim_create_inferior): No longer pass start_address to
sim_create_inferior.
Tue Apr 15 15:31:09 1997 Stan Shebs <shebs@andros.cygnus.com>
* remote.c (get_offsets): Don't use scanf for interpreting
response to qOffsets.
Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
* gdbserver/Makefile.in (INSTALL_XFORM): Remove.
(INSTALL_XFORM1): Remove.
(install-only): Use $(program_transform_name) directly, rather
than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
(uninstall): Transform name.
Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
* remote-mips.c (mips_load): Ensure that PC gets updated
after a load on LSI target.
Mon Apr 14 15:54:51 1997 Geoffrey Noer <noer@pizza.cygnus.com>
* procfs.c (notice_signals): fix typo
Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
* gdbserver/Makefile.in (INSTALL): Change install.sh to
install-sh.
Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
* config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
since gcc automatically includes it
Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
* procfs.c: Substantial (but incomplete) changes to support
sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
struct now has substructs like struct flt_ctl instead of
just a fltset_t and has a ctl_fd, status_fd, as_fd, and
map_fd instead of a single fd. Non-sysv4.2mp procfs models
still have the structs and multiple fds, but don't use the
entire struct and the four fds all point to the same thing.
We use PROCFS_USE_READ_WRITE to decide whether to talk to
procfs with reads/writes or use ioctl instead. We use
HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
multiple fds or not. PROC_NAME_FMT is split out into
CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
STATUS_PROC_NAME_FMT.
(procfs_notice_signals): now a necessary wrapper around
(notice_signals): which are the new guts for noticing signals
(open_proc_file): gets a new flag arg used in sysv4.2mp to
determine whether or not to attempt to open the ctl_fd.
(procfs_read_status): new local function, reads procfs status
(procfs_write_pcwstop): new local function, writes a PCWSTOP
(procfs_write_pckill): new local function, writes a PCKILL
(unconditionally_kill_inferior): remove signo since we now
just call procfs_write_pckill().
(procfs_xfer_memory): call lseek with SEEK_SET rather than 0
(proc_iterate_over_mappings): the whole function is ifdefed
on UNIXWARE to keep things readable.
Expanded the syscall_table to include new potential sysv4.2mp
members. Note that all ifdefs of UNIXWARE should be eliminated
if possible or renamed to describe what's being selected for a
bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
IRIX specific code now also checks it's not UNIXWARE.
* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
"/debug/%d" as PROC_NAME_FMT used to be
Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
* mn10300-tdep.c: Almost completely rewritten based on mn10200
port.
* config/mn10300/tm-mn10300.h: Likewise.
Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
* config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
lousy out-of-date clone of remote.c.
Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
* remote.c: Fix problems realized while showering.
* (hexnumlen): Add prototype. Use max, not min.
* (remote_write_bytes remote_read_bytes): Fix max packet size
calculations to properly account for packet overhead. Also handle
(probably rare) case where remote_register_buf_size isn't set.
* remote.c: Fix doc for `C' and `S' commands to indicate full
address.
* (remote_ops extended_remote_ops remote_desc remote_write_size):
Make static.
* (remote_fetch_registers remote_write_bytes remote_read_bytes):
Record size of response to fetch registers command, use this to
limit size of memory read and write commands.
* (push_remote_target): New function to make it possible to have
another target switch to the remote target.
* target.h: Add prototype for push_remote_target.
* sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
for hosts which default to unsigned chars (such as SGI's).
* (_initialize_sh_tdep): Don't set remote_write_size. It's now
handled automatically in remote.c.
Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
* blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
find_pc_sect_function(), find_pc_sect_partial_function(): new
functions for debugging overlays; pc without section is ambiguous.
* breakpoint.[ch]: add section pointer to breakpoint struct;
add section argument to check_duplicates(); check section as well
as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
breakpoint_thread_match(), bpstat_stop_status()];
add section argument to describe_other_breakpoints();
use INIT_SAL() macro to zero-out new sal structures;
make resolve_sal_pc() fix up the sal's section as well as its pc;
match on section + pc in clear_command() and delete_breakpoint();
account for overlay sections in insert_breakpoints(),
remove_breakpoint() and breakpoint_re_set_one();
all this to support overlays where a PC is not unique.
* exec.c: change xfer_memory() to handle overlay sections.
* findvar.c: change read_var_value() to handle overlay sections.
* frame.h: declaration for block_for_pc_sect() [blockframe.c].
* infcmd.c: jump_command() warns against jumping into an overlay
that's not in memory. Also use INIT_SAL() to initialize sals.
* infrun.c: wait_for_inferior() sets a flag to invalidate cached
overlay state information; Also use INIT_SAL() to init sals.
* m32r-rom.c: modify load routines to use LMA instead of VMA.
* m32r-stub.c: mask exit value down to 8 bits; screen out any
memory read/writes in the range 600000 to a00000, and ff680000
to ff800000 (hangs because nothing is mapped there); fix strcpy().
* maint.c: maintenance command "translate-address" supports overlays.
* minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
* objfiles.[ch]: add ovly_mapped field to the obj_section struct;
this constitutes gdb's internal overlay mapping table. Add macro
ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
Add function find_pc_sect_section().
* printcmd.c: modify print_address_symbolic() with overlay smarts;
modify address_info() with overlay smarts; add function sym_info()
to support the INFO SYMBOL command (translate address to symbol(s));
modify disassemble_command() to work on unmapped overlays.
* source.c: use INIT_SAL() to initialize sals.
* symfile.[ch]: change generic_load() to use section's LMA address
instead of VMA address, for overlay sections.
Add numerous functions for finding a PC's section / overlay,
translating between VMA and LMA address ranges, determining if an
overlay section is mapped, etc. Add several user commands for
overlay debugging. Add support for a "generic" form of automatically
reading overlay mapping info from the inferior (based on the default
(simple) overlay manager which Cygnus provides as an example).
* symtab.[ch]: add functions find_pc_sect_symtab(),
find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
for lookup; modify lookup_symbol and decode_line_1() to use them;
modify find_function_start_sal() to account for overlay sections;
add macro INIT_SAL() for initializing struct symtab_and_line.
* target.c: fix a comment in the declaration of target_ops.
Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
* mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
mips_skip_stub, mips_ignore_helper): New functions for dealing

INIT_FRAME_PC_FIRST macro; includes code from old macro plus
new code to skip over MIPS16 thunks.
(mips_frame_chain): Skip over MIPS16 thunks.
* config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
