* infrun.c (set/show scheduler-locking) New command. Set a
mode bit that will control how GDB attempts to control thread
scheduling for step, continue, etc. (resume): make use of
the schedule-locking mode.
* target.h (struct target_ops): new field to_has_thread_control.
* sol-thread.c: initialize target_ops to_has_thread_control.

* gdb.texinfo: Changes made as part of a project to merge in
changes made by HP. Documentation makes extensive use of
@ifclear HPPA and @ifset HPPA. The HP manual omits doumentation
on remote debugging. There are differences in documentation
(HP vs. non-HP) on C++ support (aCC vs. gnu gcc++). Also,
the HP manual discusses catchpoints, hardware watchpoints, and
some HPUX specific limitations for shared library support.
There are also a number of @node changes.
* gdbint.texinfo (Formatting): Disambiguate a sentence.
(C Usage): Same.
I am stupid, so I had trouble reading these two sentences.
Now I can read them, so I am happy.
* gdb.texinfo (Shell Commands): fixed messages about shell usage.
HP was insisting on C shell. Now all UNIX platforms have the
same message. removed @ifset HPPA and @ifclear HPPA
Tue Jan 12 17:00:00 1999 Edith Epstein <eepstein@sophia.cygnus.com>
* inftarg.c (child_create_inferior): fixed HPUXHPPA specific
call to fork_inferior. The shell param is now NULL.

called from wait_for_inferior. Instead, if a new thread-id is
detected, call add_thread. (MAGIC_NULL_PID): new macro, use
instead of the magic number "42000". (remote_find_new_threads):
if inferior_pid is unknown, get and use the current thread id.
(remote_start_remote): on connecting, attempt to get the current
thread id for inferior_pid. (remote_resume): If pid == -1,
then resume any-thread (not the current thread specifically).
* thread.c (info_threads_command): don't initialize current_pid
until after call to FIND_NEW_THREADS (which may change inferior_pid).

* configure.in (TERM_LIB): Search for the appropriate term library
on the host system.
* configure: Regenerated.
* Makefile.in (TERMCAP): Set based on autoconf check.
* config/*/*.mh: Don't override TERMCAP setting.

* top.c: #include <readline/history.h> instead of "history.h".
* tracepoint.c: Likewise.
* mac-xdep.c: Likewise.
* blockframe.c (get_frame_saved_regs): If the saved_regs_addr ptr
is null, ensure that saved registers are copied from the local
variable that was used to obtain them.
* remote-rdp.c (rdp_init): Don't discard first character on reset.
(translate_open_mode): Define table.
(exec_swi): Handle SWI_Clock. SWI_Open now handles stdin/stdout.
SWI_Write returns number of bytes not written. SWI_Read does the
same. SWI_Seek should return success/failure flag. Fix SWI_Flen.

(monitor_error): Call error after converting string into printable
format.
(monitor_printf{,_noecho}): If EXTRA_RDEBUG is defined, convert string
into printable form before printing.

Introduce new macro FRAME_INIT_SAVED_REGS which replaces
FRAME_FIND_SAVED_REGS.
Document.
Use in mn10300 and rs6000 targets. Fix side effects on ALPHA, MIPS,
Z8K and SPARC targets.
* configure.in (with-sim-gpu2): Do not emit a -L argument without
an associated pathname. Link in the math library after the gpu2
library.
Assumes that libm is around (and doesn't take advantage of the
AC_CHECK_LIB(m) that is already in configure.in), but this is a
minor point and unlikely to cause problems.
* config/xm-aix4.h (SIGWINCH_HANDLER): Function `aix_resize_window'
must accept a signal number as parameter.

Merged in m68k-linux patch from Andreas Schwab
1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* Makefile.in, configure.host, configure.tgt: Add support for
m68k-linux.
* config/m68k/linux.mh: New file.
* config/m68k/linux.mt: New file.
* config/m68k/nm-linux.h: New file.
* config/m68k/tm-linux.h: New file.
* config/m68k/xm-linux.h: New file.
* gdb/m68klinux-nat.c: New file.
* gdbserver/low-linux.c: Add support for m68k-linux.
* gdb/config/m68k/tm-m68k.h (NUM_FREGS): New macro.
* config/m68k/tm-m68k.h (NUM_FREGS): m68k-linux patch.
Added NUM_FREGS macro.
* config/m68k/xm-linux.h: m68k-linux patch. New file.
* config/m68k/tm-linux.h: m68k-linux patch. New file.
* config/m68k/nm-linux.h: m68k-linux patch. New file.
* config/m68k/linux.mt: m68k-linux patch. New file.
* config/m68k/linux.mh: m68k-linux patch. New file.
* gdbserver/low-linux.c: m68k-linux patch. Added an ifdef
that checks the value of __GLIBC to decide whether or
not to include sys/reg.h.
* m68klinux-nat.c: m68k-linux patch. New file. Note
both m68k-tdep.c and m68klinux-nat.c contain definitions
for supply_gregset and supply_fpregset. The definitions
in m68k-tdep.c are valid is USE_PROC_FS is defined. Otherwise,
the definitions in m68klinux-nat.c will be used. This is a
bit of a hack. The supply_* routines do not belong in
*_tdep.c files. But, there are several lynx ports that currently
depend on these definitions.
* configure.tgt: m68k-linux patch. Added m68*-*-linux*
gdb_target.
* configure.host: m68k-linux patch. Added m68*-*-linux*
gdb_host.
* Makefile.in: m68k-linux patch. Added compile line for
m68klinux-nat.o
* config/i386/xm-cygwin.h: Remove REQUEST_QUIT definition.
* config/powerpc/xm-cygwin.h: Ditto.

the stack frame. Their offset from the previous stack frame is in
fdata.gpr_offset and fdata.fpr_offset, not fdata.offset.
(gdb.base/return.exp)
* config/rs6000/tm-rs6000.h: Doc fixes.
* monitor.c (monitor_read_memory): Zero out pattern buffers
before calling re_search.
(parse_register_dump): Ditto.
PR 18049. This bug had existed erratically since I upgraded to
the new gnu-regex.c this last summer. The problem is mostly in
parse_register_dump; the allocated structure has some random values
in it and there is a flag set in the register_pattern structure by the
gnu-regex library which indicates that the values in the re_registers
should be trusted.
If those arbitrary contents aren't zero, gnu-regex tries to run realloc
on them and we get a core dump on some hosts for some targets when the
moon is just right.
* m32r-tdep.c (decode_prologue): If no branch or push fp is found,
but there's a stack adjust, then use that as the end of prologue.
(m32r_skip_prologue): don't skip past the first line if there is
line info. (m32r_virtual_frame_pointer): new function.
(m32r_fix_call_dummy): no return value needed.
* tracepoint.c: Move default definition of
TARGET_VIRTUAL_FRAME_POINTER from here to target.h.
* target.h: Add default definition of TARGET_VIRTUAL_FRAME_POINTER.
* ax-gdb.c (gen_frame_args_address, gen_frame_locals_address):
use TARGET_VIRTUAL_FRAME_POINTER to determine frame pointer.
(gen_trace_for_expr): new argument, address of tracepoint,
gets passed to new_agent_expr and added to struct agent_expr.
(is_nontrivial_conversion): call to new_agent_expr now requires
a dummy argument. (agent_command): use get_current_frame() to
get current PC scope; pass it to gen_trace_for_expr.
* ax-general.c (new_agent_expr): new argument, address of
tracepoint; store it in new field of struct agent_expr.
* ax.h (struct agent_expr): add new field for tracepoint address.
* ax-gdb.h: change prototypes to match above changes.
(CHILL_PRODUCER, etc): Comment out descriptions, not useful.
(IN_SOLIB_CALL_TRAMPOLINE): Rename info from IN_SOLIB_TRAMPOLINE.
(IN_SOLIB_RETURN_TRAMPOLINE): Describe.
(KERNEL_DEBUGGING, MIPSEL): No info about these, remove.
* config/mn10300/tm-mn10300.h (TARGET_VIRTUAL_FRAME_POINTER):
new target macro.
* mn10300-tdep.c (mn10300_virtual_frame_pointer): new function.
* tracepoint.c (encode_actions): Use the new target macro to
determine the virtual frame pointer, for collecting locals/args.
(add_local_symbols, collect_symbol): add a register/offset pair of
arguments so that the virtual frame pointer can be passed in.
Convert mn10300, MIPS and powerpc/rs6000 targets to use
BREAKPOINT_FROM_PC
Delete global variable memory_breakpoint_size. Use BREAKPOINT_FROM_PC
instead.
* symfile.c (deduce_language_from_filename): rewrite so as to
work from a table of filename extensions, modifiable by the user.
(filename_language_table): new data structure.
(set_ext_lang_command): new function for new command, "set
extension-language". (info_extension_language_command): new
function for new command "info extension-languages".
(add_filename_language, init_filename_language_table): new
support functions for the above.
* language.c (language_enum): new function. Support for above.
* coffread.c (coff_symtab_read): Discard C_LABEL's that are not
function entry points, to avoid getting them in the stack dump
instead of the actual function.
without NAT_FILE definition, configure will assume that GDB cannot
run native.
* config/m68k/nm-delta68.h (KERNEL_U_SIZE): New macro.
* delta68-nat.c (kernel_u_size): New function.
* rdi-share/host.h: if compiling under Cygwin, make sure new
preprocessor define is defined. Define it if not.
* rdi-share/hostchan.h: ditto
* rdi-share/aclocal.m4: regenerate
* rdi-share/configure: regenerate
* rdi-share/host.h: if compiling under Cygwin, make sure new
preprocessor define is defined. Define it if not.
* rdi-share/aclocal.m4: regenerate
* rdi-share/configure: regenerate
* gdbtk-cmds.c: Can't start using new API names yet. Switch
back
to calling cygwin32_ funcs until some time has passed...
* gdbtk.c: Ditto. Also, include sys/cygwin.h for Cygwin,
instead
of providing own proto.
Changes to account for name change from cygwin32 to cygwin and
clean up Win32-related ifdefs.
* configure.tgt: check for cygwin* instead of cygwin32.
New cygwin gdb_target variable loses the "32".
* configure.host: check for cygwin* instead of cygwin32.
New cygwin gdb_host variable loses the "32".
* configure.in: test __CYGWIN__ instead of __CYGWIN32__,
rename gdb_cv_os_cygwin32 variable to drop the "32". Call
AM_EXEEXT instead of AC_EXEEXT since that isn't in a released
autoconf yet.
* configure: regenerate.
* main.c: drop "32" from cygwin_ funcs, include sys/cygwin.h
where
cygwin path conv protos live, instead of adding a proto here
for
them here.
* {main.c, ser-tcp.c, ser-unix.c, top.c}: check __CYGWIN__
instead of __CYGWIN32__.
* source.c: thoughout, check _WIN32 instead of WIN32.
* config/i386/cygwin32.mh: delete.
* config/i386/cygwin.mh: new file, was cygwin32.mh.
* config/i386/cygwin32.mt: delete.

multithread debugging.
(remote_get_threadlist) : get a partial list of threads
(remote_threadlist_iterator) : Step through all the threads
(init_remote_threadtests) : Optional builtin unit test commands.
* thread.c (bind_target_thread_vector) : Implementa a more dynamic
way of accessing target specific thread info functions than
FIND_NEW_THREADS.
(target_thread_info) : Function to get extended thread information.
* gdbthread.h : Export internal data structures corresponding to
external detailed thread info response. This is more like a 'ps'
command than what might be expected of host based threads. This
is for embedded systems.
* console.tcl (complete): I added the ability to pass from_tty
from gdb_cmd to the underlying commands. Pass 1 when the
command is invoked from the console.
* interface.tcl (gdbtk_tcl_tstart, gdbtk_tcl_tstop): Run the
src window's do_tstop method rather than manipulating the
widgets by hand.
* src.tcl (build_win): Redo the packing so that the function
combobox doesn't push all the other combo-boxes off the screen
if it has a very long function name in it.
* srcbar.tcl (do_tstop): Added a mode that just changes the
GUI, which can be called from console hooks.
* srctextwin.tcl: Fixed some bugs I introduced in setting
breakpoints in the assembly & mixed mode windows. Dropped
the notion of joint breakpoint images for lines that have
breakpoints of two separate types. Too fragile.
Also added the "dont_change_appearance" flag, used in the
continue_to_here method to tell the GUI not to reflect the
temporary disabling of all the breakpoints.
* toolbar.tcl (insert_buttons): Added a little more error-checking.
Thu Nov 12 15:20:15 1998 Jim Ingham <jingham@cygnus.com>
* gdbtk-cmds.c (gdb_cmd): Added an optional second argument to the
gdb_cmd, which is from_tty. This is passed to the gdb command
parser. It is 0 by default, and the console window passes 1.
* gdbtk-cmds.c: moved disassemble_from_exec from gdbtk.c to gdbtk-cmds.c
with all the other link-var'ed variables
* gdbtk-hooks.c (gdbtk_trace_find): Only run the hook functions if
we are called from_tty.
* gdbtk-hooks.c (gdbtk_trace_start_stop): Set the trace buttons
from a trace_start_command callback rather than doing it as a
special case in gdb_cmd.
* tracepoint.c (tstart_command, tstop_command): Add call to
trace_start_stop_hook here.
