Changes to OCD support to support wiggler box as well as
target boxes:
* ocd.c: change speed in init command to 0 from 80,
add (temporary) logging commands to help debugging,
(ocd_open): if "target ocd wiggler lpt" then use special
ser-ocd.c serial interface which communicates with Wigglers.dll,
otherwise do as we did before
(ocd_get_packet): add OCD_LOG_FILE and OCD_SET_CONNECTION to
switch of known commands of len 0
* ocd.h: add OCD_LOG_FILE
* serial.c (serial_open): do serial_interface_lookup on ocd
in the case of ocd
* ser-ocd.c: add buffer to contain responses from sending a
command to the Wigglers.dll.
(ocd_readchar): return curr char from buffer and increment ptr
(ocd_write): send buffer to Wigglers.dll, storing response in
return buffer and initializing curr location ptr to start of
buffer.
Nomenclature change. BDM is a specific type of OCD
(On chip debugging). Wiggler is the parallel port box controlled
by Wigglers.dll. The faster target box from Macraigor Systems
is not a wiggler.
* ocd.c:
* ocd.h:
* ppc-bdm.c:
* ser-ocd.c:
Replace all instances of "wiggler_" with "ocd_" and change most other
instances of "wiggler" to "ocd" or "ocd device" depending on context.
* config/m68k/monitor.mt: remove remote-wiggler.o from TDEPFILES
until OCD with that target is supported again.
* Makefile.in: add DLLTOOL = @DLLTOOL@, pass on DLLTOOL to
sub makes, change clean rule to also remove *.a to remove
libwigglers.a, in dependencies: add ppc-bdm.o ocd.o ser-ocd.o and
remove remote-wiggler.o
* configure.in: add DLLTOOL support
* configure: regenerate
* wigglers.def: new file for imports for wigglers.dll
* ser-ocd.c: new file which is layer between ocd.c and either the
wigglers.dll or the target box, only stub so far
* config/powerpc/ppc-eabi.mt: add ppc-bdm.o to TDEPFILES
* config/powerpc/ppc-sim.mt: add ppc-bdm.o to TDEPFILES

Download routine now switches to remote target automatically.
* top.c (disconnect): Only define if SIGHUP is defined. Cleans
up MSVC/Win32 problem.
* utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout
or gdb_stderr.
* config/sh/tm-sh.h: Define TARGET_SH for WinGDB.
* config/sparc/tm-sparclet.h: Remove override for prompt.
o Provide poll_quit callback to simulators
so that they can poll for SIGINT on
clueless OS's.
o Add sim_stop to simulators so that clients
can request a halt (eg gdbtk's STOP button)
Works for PPC!
o Re-arange remote-sim.c so that the
hard work is moved from gdbsim_resume()
to gdbsim_wait() (where it should be).
(INSTALL_XFORM1): Remove.
(install-only): Use $(program_transform_name) directly, rather
than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
(uninstall): Transform name.
* 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
* (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.
address.

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.
* gdb.base/help.exp: update help msg for INFO ADDR; add help test
for INFO SYMBOL; add help tests for OVERLAY commands.
* gdb.base/default.exp: add tests for INFO SYMBOL command;

* gdb.base/sigall.c: add usestubs code frag
* gdb.base/watchpoint.c: turn on complex watchpoint test for M32R.
Except for the two m32r modules, this checkin is for
overlay support.
* 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.

and it's not already set.
* gdb.base/setshow.exp: Only test the run command if the target
isn't using a stub and if it supports argument passing.

where the objfile is reordered and contains both coff and
stabs debugging info (continue on if a psymtab isn't found).
* gdb.disasm/mn10300.exp: Run mn10300 disassembler tests.
* gdb.disasm/Makefile.in: Remove "mn10300" when cleaning.
disassembler testsuite for the mn10300.
