with EINTR, retry the call.
* gregset.h: New file. Typedefs for gdb_gregset_t and
gdb_fpregset_t, prototypes for supply_gregset and friends.
* procfs.c: Include gregset.h. Delete local prototypes for
supply_gregset etc., and local typedef gdb_gregset_t etc.
* sol-thread.c: Include gregset.h, delete local prototypes,
add appropriate casts to gdb_gregset_t.
* uw-thread.c, lin-thread.c, core-sol2.c, core-regset.c,

close_with_trace, wait_with_trace, lseek_with_trace):
Report errno if an error occurs in a system call.
(write_with_trace): Make 2nd arg void *, to agree with write.
* procfs.c (many functions): change int cmd; to long cmd;
Solaris /proc API calls this parameter a long, and requires it
for 64-bit hosts (where sizeof(long) != sizeof(int)). UnixWare
calls it an int, but on existing UnixWare hosts, int and long
are the same size. So long it must be. If a future UnixWare
version has problems with this, we'll have to use autoconf.
* proc-api.c (write_with_trace): use long instead of int.
* procfs.c (comments): Eliminate "???" in comments, which GCC
wants to interpret as a trigraph. (fill_gregset, supply_gregset,
fill_fpregset, supply_fpregset): declare.
(procfs_wait): Sysargs is a long, change printf format to match.

for UnixWare / SVR4.2MP targets and any targets which use
multi-file /proc entries. Fixed support for hardware watchpoints.

as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
NOTE: I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do. So configuring for UnixWare
may not work just yet.
Update support for x86 Solaris 2.
* config/i386/tm-i386sol2.h, nm-i386sol2.h: New configuration
files for x86 Solaris 2.

* config/sparc/tm-sun4sol2.h (PROCFS_GET_CARRY): New macro, extract
carry flag from a given regset.
(IS_STATIC_TRANSFORM_NAME): New macro, check if a symbol name

to check for a SunPro transformed symbol name.
unconditionally_kill_inferior): Undo Oct 26 1996 and Apr 26 1997
changes to trace PRFS_STOPTERM and handle PR_DEAD.
These changes tried to work around a problem with an early DU 4.0
release, but they trigger subtle timing dependent kernel bugs
in older OSF/1 releases.
* procfs.c (init_procinfo): new function, abstracts some code
shared by create_procinfo and do_attach;
(procfs_set_inferior_syscall_traps): new function, abstracts
some code needed by procfs_init_inferior, do_attach, and
procfs_lwp_creation_handler; (procfs_first_available): new
function, find any LWP that's runnable; (procfs_thread_alive):
replace stub function with real implementation;
(procfs_lwp_creation_handler): fix bug starting new child
threads; (info_proc): bug fixes and enhancements for the
"INFO PROCESSES" command; (close_procinfo_file): call new
function "delete_thread" to cleanup GDB's thread database;
(proc_init_failed): add new argument "kill", to control whether
process is killed (so this function can be shared by
create_procinfo and do_attach); (procfs_exit_handler): handle
exit from an attached process, and cleanup procinfo handles
when the process exits; (procfs_resume, procfs_wait): cleanup
after a thread when it exits; (do_attach, do_detach): handle
attached processes with multiple threads; plus some general
improvements in the diagnostic output.

call; (sol_thread_mourn_inferior): add unpush_target call;
(sol_thread_wait, sol_thread_resume): enhance to deal with
thread exit cleanly; (sol_thread_new_objfile,
sol_thread_pid_to_str): detect unsuccessful startup and
don't crash; plus some general cleanup.

(procfs_notice_signals): Copy traced signal set back to
pi->prrun.pr_trace.
(unconditionally_kill_inferior): If PR_DEAD is defined,
rerun inferior after killing it.
* 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

returns its argument unchanged.
* inflow.c (terminal_init_inferior): Eliminate #ifdef
of PIDGET and fold both alternatives into common code.

the entry to the exit system call to detect termination of the
inferior stopped working. Trace termination of the inferior via
PRFS_STOPTERM instead.
(procfs_init_inferior): Do not trace entry to exit system call
if PIOCSSPCACT is defined.
(procfs_wait): Handle PR_DEAD event, which signals the termination
of the inferior if PRFS_STOPTERM is set.

which supply_register is called to fix bug with writing writing
individual regs.
* config/sparc/tm-sun4sol2.h: Define default for
target_pid_to_str in case host lacks libthread_db.
config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh
config/sparc/tm-sun4sol2.h: Use autoconf to config Solaris thread
and pthread support, since pre-2.5 systems don't come with
libthread_db.so.1.
* procfs.c (info_proc): Use int instead of id_t. Old versions of
Irix don't see to define this.
infrun.c, mac-nat.c, procfs.c, remote.c, sol-thread.c, thread.c,
win32-nat.c, config/nm-lynx.h: Rename thread.h to gdbthread.h to
avoid conflict with Solaris /usr/include/thread.h.

the removal of all symbol tables.
* target.c (push_target): Make sure that to_close is non-zero
before calling it.

alpha_find_saved_regs if fi->saved_regs is still NULL.
* elfread.c (elf_symtab_read): Ensure that the filename field
of a minsym is nonempty. Ignore solib trampoline symbols from

* config/pa/nm-hppab.h (STOPPED_BY_WATCHPOINT): Define.
(HAVE_STEPPABLE_WATCHPOINT): Define.
(TARGET_CAN_USE_HARDWARE_WATCHPOINT): Define.
(target_{insert,delete}_watchpoint): Define.
GNUTARGET.
* putenv.c: Removed, conflicts with system declaration of
putenv on RS/6000 running AIX 3.2.5, and above change makes it
unnecessary.
* Makefile.in: Change accordingly.
* procfs.c (procfs_create_inferior): Change comment accordingly.
* procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
m3-nat.c (m3_create_inferior): Pass it.
* procfs.c: Remove ptrace function. It was declared in a way which
conflicted with the prototype in unistd.h on Solaris.
* Move target_signal_from_host, target_signal_to_host, and
store_waitstatus from inftarg.c to target.c. procfs needs them.
* target.c: Include "wait.h" and <signal.h>.
* target.h, infrun.c (proceed), proceed callers: Pass new code
TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
enums being treated as unsigned and is cleaner.
* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
TARGET_SIGNAL_0.
* infcmd.c (signal_command), infrun.c (signals_info):
Don't allow user to specify numeric equivalent of
TARGET_SIGNAL_DEFAULT.
