* sol-thread.c (ps_pglobal_lookup): Change argument type from paddr_t to psaddr_t. This mistake appears to date from an erroneous man page in Solaris 2.5 -- the correct type from the system headers has always been psaddr_t. (ps_pdread, ps_pdwrite, ps_ptread, ps_ptwrite): ditto. (rw_common): ditto.

1998-04-02* Fixes for PR 14571.Frank Ch. Eigler1-0/+7
Thu Apr 2 12:47:41 1998 Frank Ch. Eigler <fche@cygnus.com> * sol-thread.c (sol_thread_store_registers): Save & restore new value of single updated register to prevent accidental clobbering.
1997-12-03fixes for debugging threaded core files. Previously gdb would find theDavid Taylor1-8/+136
kernel threads but would get errors on each of the user threads that wasn't currently assigned to a kernel thread. PR's gdb/13803 (and gdb/13618).
1997-10-24fix for PR 13618 -- gdb incorrectly reports thread information.David Taylor1-0/+37
If other systems besides nm-sun4sol2 exhibit the problem, they may need definitions of FIND_NEW_THREADS and a corresponding support function.

* sol-thread.c (sol_thread_[store, fetch]_registers): if inferior_pid is an LWP rather than a Solaris thread, let procfs handle the request. (rw_common, sol_thread_xfer_memory): procfs_xfer_memory will only work if inferior_pid points to an LWP (rather than a Solaris thread). Use procfs_first_available to find a good LWP. (info_solthreads): added a maintenance command to list all known Solaris threads and their attributes.

1996-06-11 * Makefile.in (INTERNAL_LDFLAGS): Add in flags from configure.Stu Grossman1-19/+115
* configure configure.in: Only make sol-thread.o for native. Also, switch to dlopened libthread_db.so.1. * sol-thread.c: Switch to using dlopen to get the thread_db library.
1996-05-15 * procfs.c (procfs_thread_alive procfs_stop): Make static.Stu Grossman1-19/+16
* (procfs_pid_to_str): New routine to print out thread id's in an intelligible manner. * sol-thread.c (sol_thread_fetch_registers): Re-order manner in 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.

* (sol_thread_resume): Prevent people from trying to step inactive threads. * (sol_thread_wait sol_thread_fetch_registers sol_thread_store_registers): Remove unnecessary check for sol_thread_active. These routines won't get called unless threads are active.
1996-05-10 * sol-thread.c: Cleanup. gcc -Wall fixes. Add prototypes.Stu Grossman1-173/+258
Print out messages instead of codes for thread_db errors. Make access macros for thread and lwp manipulation. Make cleanups to fixup inferior_pid in case of errors.
1996-05-09 * Makefile.in, breakpoint.c, corelow.c, fork-child.c, inflow.c,Stu Grossman1-1/+1
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.

returns a possibly modified pid. * inftarg.c (ptrace_him): Now returns pid; * m3-nat.c (m3_trace_him): Now returns pid; * infcmd.c (run_command): Minor cleanup. * infrun.c (wait_for_inferior): Add another check for one_stepped near where we read the pc to avoid erroneously setting random_signal for multi-threaded support. * procfs.c: Add support for Solaris LWPs. Remove def of LOSING_POLL. Many cleanups... Several workarounds for Solaris lossage. System call entry and exit are now handled by dynamically registered handlers. * (syscallname): Don't barf when handed an unknown syscall number. * (info_proc_syscalls): Ditto. * sol-thread.c: New file. Implements Solaris thread support. * symfile.c (symbol_file_add): Add call to target_new_objfile to notify target-dependent code about new symbol tables. * (clear_symtab_users): Call target_new_objfile to notify it of the removal of all symbol tables. * target.c (push_target): Make sure that to_close is non-zero before calling it. * target.h (target_new_objfile): Provide default. * config/alpha/nm-osf2.h: Define LOSING_POLL because this version of OSF can't hack using poll with /proc. * config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be sol-thread-new-objfile. * config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and add libthread_db.so.1 to NAT_CLIBS. * config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and target_pid_to_str.
