executing_breakpoint_commands if we are interrupted by error.
* coffread.c (init_lineno): Avoid problem with zero-sized linetab
versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
* core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
catch_errors() so we can setup the frame regardless of whether
the shared libs work.
* ieee-float.c (double_to_ieee_extended): Get exponent from
right place in little-endian systems. From John Carey.
* blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
returns 0, there is no previous frame.
* breakpoint.c (commands_command): If !from_tty, don't call
input_from_terminal_p().
* dbxread.c (record_misc_function): Speed up slightly.
(compare_psymbols): Ditto.
* infcmd.c (do_registers_info): Take a second argument to
determine whether to print float registers. "info registers"
does not do so anymore. "info all-registers" does, now.
* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
arg and ignore it.
* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.

[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
(gdb_readline): Make call-compatible with readline.
(init_signals): Improve comments re vfork vs. signal.
* utils.c (prompt_for_continue): Use new gdb_readline().
If we prompt for continuation, we don't let CR repeat the previous
command, once we get back to a prompt. It's too easy to keep
hitting CR, expecting "--more--" prompts, and have some long
command start repeating on you.
modifies static state in the parent process; new_tty itself
runs in the child and modifies the child's file descriptors
to match the saved static state.
* infrun.c (child_create_inferior): Call new_tty_prefork,
fork, then new_tty.
remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
from target_ops. It's the same on all targets. Add two section
pointers to target_ops.
section list is to be added to, if any. Reallocate the
sections in that target to add any that come from shared libs.
(throughout) so_sections renamed to sections.
(solib_xfer_memory): Deleted.
* tm-sunos.h (SOLIB_ADD): Add target argument.
(SOLIB_XFER_MEMORY): Delete.
* xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
and add comment explaining shared library screw.
section table pointers and bfd* into the target_ops.
(core_open): Allow errors in shared lib reading, etc.
(core_files_info): Describe shared library sections.
* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
exec_files_info, set_section_command): Move section table
pointers and bfd* into the target_ops.
(add_to_section_table): Add BFD to section table.
* target.c (target_xfer_memory, target_info): Pass target to
xfer_memory and target_info functions.
* target.h: ''
* gdbcore.h: Move struct section_table.
* target.h: New home of struct section_table.
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
Define two variants, one faster.
* sparc-tdep.c (sparc_frame_chain): Use target_read_memory
and return zero, rather than giving an error.
(setup_arbitrary_frame): Initialize the PC in the new frame.
(skip_prologue): Add a second arg saying whether we're just
checking for a frameless function or not.
The child can be proceeded from inside wait_for_inferior in
evaluating breakpoint conditions, and DO_DEFERRED_STORES was
getting skipped in that case.
* expprint.c (print_subexp): Use filtered output, since the
subroutines we call use it, otherwise the output is horribly
mangled, since output of wrappable stuff comes out late.
@example/@end example. Without this it formatted fine by
texinfo-format-buffer in Emacs, but makeinfo insisted on paragraphing
it!
Also removed "gdb/" from in front of one instance of libiberty...
Minor typo and formatting fixes; incorporated most fixes remaining from
filed mail commenting on earlier drafts.
Added warnings: pipes don't work in run command;
conditions are converse of assertions;
step over fn without debug info goes to next fn;
vars may have "wrong" values near fn entrance, exit
Added example from Kingston on printing repeated nonadjacent values
Added explicit mention that in Emacs gdb mode C-c and C-z are like
shell mode for signals
Improved installation directions in appendix, added manual formatting
instructions
Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
doesn't sound so much like its parent "Stopping and Continuing"; also
moved entries on continue to top of section, so they don't get lost.

(2) Eliminated use of @footnote---had my doubts about it anyways, and
it's broken in latest texinfo
(3) Introduced *some* use of [] for optional arguments, where
explanation is not simpler by listing cmd w arg and cmd w/out arg
separately. Still not using @deffn.
(4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
couple of headings are too long. Need patches to texinfo or revision
to GPL-2.

for either generic manual (material near back, in "targets"), or for special
cross-debugging manuals (material near front, in "invocation").
2) Allowed $Id: tag to appear as texinfo comment.
2) allowed $Id: tag to appear in post-M4 file by turning it into texinfo

3) Disabled @group where no longer supported by texinfo
* TODO: Document work needed on &fn and &array.

and external_aouthdr), byte-swap the fields that we care about
before using them, and make the file header data local to
read_the_mips_symtab rather than global.
* configure.in, Makefile.in: Avoid rebuilding "depend" as much.
Avoid declaring Makefile dependencies, because GNU Make stupidly
tries to update it if we do.
* coffread.c: Revise for minor changes to bfd internal coff
indexes.
* configure: If -template= is given a relative path, make it
absolute before recurring in subdirectories.
docn into separate sections---basically chapters, plus two loose
pieces that can be configured to go in different places. This
allows GNU m4 to preprocess the manual without coredumping.

numbering: the version of the manual is the version of the layout file.

* main.c: Include with "..." form for non-system include files,
so "gcc -MM" for "make depend" works.
Include readline files with "...h" rather than <readline/...h>.
instructions to "Targets" chapter for generic manuals, while
leaving them up front for manuals specific to specialized
environments; apply fixes from RMS comments through chapter 4.
* pretex.m4: modify explanatory text slightly (and redefine
"regexp") to keep GNU m4 from complaining. (It still crashes
later, but one step at a time...)
stuff for config manual) here where it counts; updated
to use new subdir structure (gdb/doc/).
* Makefile: generated from above via
config.gdb none

files, formatted from gdb.texinfo (via gdb-all.texinfo, see
Makefile)---but due to use of texinfo 2, can't count on makeinfo
to generate these, so we distribute them already formatted.
* gdb.texinfo: included full Info node and menu crud (as generated
by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
* Makefile: updated "gdb.dvi" target to use M4 preprocessor;
put in comments-for-future gdb.info target (one day makeinfo will
work again).
(2) Reorganized, bringing more common commands forward, merging
"print" and "x" into one section;
(3) New sections: "Essential Commands", "GDB Scripts";
(4) Material on convenience vars and value history added to "Expressions";
(5) Uses PostScript fonts by default, also includes (commented out) alternative
Computer Modern font definitions that format similarly.
* cplus-dem.c: Move CPLUS_MARKER define to after defs.h.

(3) eliminate info structural information that can be generated

1a) Isolate Nindy-960 stuff into subsection of above, and expand it;
(2) Expand GDB-under-Emacs chapter;
(3) Minor cosmetics, including small free software blurb at front to
make RMS feel better about GPL moved to back.

warn about similarity with "info targets"; document target strata rather
than stack; document "up-silently" and "down-silently"; add text about

gdb no longer prints the copyright and blurb if you specify a file
