972256e712 * corelow.c (core_close): Clear inferior_pid only if there is
an open core_bfd.

	* cp-valprint.c (cp_print_value_fields):  Pass correct address
	to val_print, not 0.

	From Andreas Schwab (schwab@issan.informatik.uni-dortmund.de):
	* eval.c (evaluate_subexp_standard) [case BINOP_REPEAT]: Chase
	typedefs before checking for integral type of right operand.

b607efe714 See gdb ChangeLog entry with header:
Thu Jul 25 19:41:31 1996  Fred Fish  <fnf@cygnus.com>

for a rather huge set of changes.  I was going to put them here, but it
made cvs dump core.  :-(

fdfa331511 * Makefile.in, breakpoint.c, corelow.c, fork-child.c, inflow.c,
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.

8eff3c7fe6 * corelow.c (add_to_thread_list): Make sure reg_sect is non-null
before de-referencing it.  Prevents deref of NULL pointer if core
	file lacks .reg section.
	* defs.h:  Rename floatformat_{to from}_long_double to
	floatformat_{to from}_doublest.  Get rid of FLOATFORMAT_{TO
	FROM}... macros.
	* findvar.c (extract_floating store_floating):  Change all refs to
	FLOATFORMAT_{FROM TO}... to floatformat_{from to}_doublest.
	* utils.c:  Change floatformat_{to from}_long_double to
	floatformat_{to from}_doublest cuz the new routines will use
	whatever size (double or long double) is appropriate.
	* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
	REGISTER_CONVERT_TO_RAW):  Change FLOATFORMAT... macros to
	floatformat... routine calls.

3c5124da49 * breakpoint.h (enum enable): New enum shlib_disabled for
shared library breakpoints that have been temporarily disabled.
        * breakpoint.c: Handle temporarily disabled shared library
        breakpoints like disabled breakpoints in most places.
        (insert_breakpoints): Use shlib_disabled to indicate
        that an unsettable breakpoint is only temporarily disabled.
        (re_enable_breakpoints_in_shlibs): New function.
        * corelow.c (solib_add_stub): After adding shared libraries,
        try to reenable any temporarily disabled breakpoints.
        * infcmd.c (attach_command): Likewise.
        * infrun.c (wait_for_inferior): Likewise.
Hopefully the last 7763 related patches for a while.

16726dd15b The point of these changes is to avoid reading the frame pointer
and stack pointer during stepping, to speed things up.
	A.  Changes to not select a frame until we need a selected frame:
	    * blockframe.c (flush_cached_frames): Call select_frame (NULL, -1).
	    * infrun.c (wait_for_inferior): Move call to select_frame back to
	    normal_stop.  This reverts a change of 13 Apr 94 (it says Jeff
	    Law, but the change was my idea); the only reason for that change
	    was so we could save and restore the selected frame in
	    wait_for_inferior, and now that flush_cached frames clears the
	    selected frame, that should work OK now.
	B.  Changes to not create a current_frame until we need one:
	    * blockframe.c (get_current_frame): If current_frame is NULL, try
	    to create an innermost frame.
	    * sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy),
	    infrun.c (wait_for_inferior), thread.c (thread_switch),
	    convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame),
	    alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command),
	    h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame),
	    hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame),
	    i960-tdep.c (pop_frame), m68k-tdep.c
	    (m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c
	    (push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c
	    (pop_frame), config/arm/tm-arm.h (POP_FRAME),
	    config/convex/tm-convex.h (POP_FRAME), config/gould/tm-pn.h
	    (POP_FRAME), config/ns32k/tm-merlin.h (POP_FRAME),
	    config/ns32k/tm-umax.h (POP_FRAME), config/tahoe/tm-tahoe.h
	    (POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't
	    call create_new_frame.
	    * corelow.c (core_open), altos-xdep.c (core_file_command),
	    arm-xdep.c (core_file_command), gould-xdep.c (core_file_command),
	    m3-nat.c (select_thread), sun386-nat.c (core_file_command),
	    umax-xdep.c (core_file_command): Don't call create_new_frame; do
	    call flush_cached_frames.
	    * blockframe.c (reinit_frame_cache): Don't call create_new_frame
	    or select_frame.
	C.  Changes to get rid of stop_frame_address and instead only
	fetch the frame pointer when we need it.
	    * breakpoint.c (bpstat_stop_status): Remove argument
	    frame_address; use FRAME_FP (get_current_frame ()).
	    * infrun.c (wait_for_inferior): Don't pass frame pointer to
	    bpstat_stop_status.
	    * infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame
	    ()) instead of stop_frame_address.
	    * infrun.c (save_inferior_status, restore_inferior_status),
	    inferior.h (struct inferior_status): Don't save and restore
	    stop_frame_address.
	    * inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c
	    (select_thread): Remove stop_frame_address and uses thereof.
	D.  Same thing for the stack pointer.
	    * infrun.c (wait_for_inferior): Remove stop_sp and replace
	    uses thereof with read_sp ().
	E.  Change to eliminate one nasty little spot where we were
	wanting to know the frame pointer from before the current step
	(idea from GDB 3.5, which saved my ass, because my other ideas of
	how to fix it were very baroque).
	    * infrun.c: Remove prev_frame_address.
	    * infrun.c (wait_for_inferior, step_over_function): Use
	    step_frame_address instead of prev_frame_address.
	F.  Same basic idea for the stack pointer.
	    * inferior.h, infcmd.c: New variable step_sp.
	    * infcmd.c (step_1, until_next_command): Set it.
	    * infrun.c: Remove prev_sp and replace uses by step_sp.
	    * infrun.c (wait_for_inferior): If we get out of the step
	    range, then set step_sp to the current stack pointer before we
	    start going again.

a91b6ec8f0 * corelow.c (core_open): Copy the modified to_sections_end

9137a6f461 * corelow.c (add_solib_stub): Remove copying of to_sections,
pass current_target to SOLIB_ADD. The Sep 10 change failed
	if SOLIB_ADD errored out, or if SOLIB_ADD was trying to access
	target memory.
	* corelow.c (core_open):  After reading the shared libraries,
	copy the modified to_sections vector from current_target to
	core_ops, so that core_close can free it later.
	* config/rs6000/nm-rs6000.h, rs6000-nat.c (xcoff_relocate_core):
	Pass down target parameter from SOLIB_ADD and use it instead of

26a859ec83 * corelow.c (add_solib_stub): Copy to_sections changes from
core_ops to current_target after adding the shared libraries.

	find_corresponding_bincl_psymtab):  Change `repeated header not seen'
	error to a complaint, simplify complaint.
	* procfs.c (signalname, errnoname):  Make `name' const.

cad1498f8a * Makefile.in: Add stuff to build nlmstub.

	* configure.in:  Add config for powerpc/Netware.

	targets work to support target overlays and inheritance.
	* corelow.c, hppa-tdep.c, inflow.c, remote-nindy.c, utils.c:

	* config/i386/tm-i386nw.h:  Enable longjmp support.  More work is
	needed to get the address of longjmp out of the target.

Jim Kingdon
842cf83162 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
rather than trying to shove an int into a pointer and back out
	again.  This avoids compiler warnings.
1994-02-06 16:16:39 +00:00
Thomas Lord
199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.
