This change breaks the behaviour of annotations with commands that span
multiple lines, like if, while, etc:
2007-01-03 Jan Kratochvil <jan.kratochvil@redhat.com>
Daniel Jacobowitz <dan@codesourcery.com>
* Makefile.in (top.o): Update.
* top.c (gdb_readline_wrapper_done, gdb_readline_wrapper_result)
(saved_after_char_processing_hook, gdb_readline_wrapper_line)
(struct gdb_readline_wrapper_cleanup, gdb_readline_wrapper_cleanup):
New.
(gdb_readline_wrapper): Rewrite to use asynchronous readline.
To see this compare the output of GDB in CVS with that of 6.6 for the simple
construct:
(gdb) if
>end
(gdb)
With 6.6, omitting ^Z^Z, (gdb -ann=3):
pre-prompt
(gdb)
prompt
if 1
post-prompt
pre-commands
>
commands
end
post-commands
pre-prompt
(gdb)
prompt
With GDB in CVS:
pre-prompt
(gdb)
prompt
if 1
post-prompt
pre-commands
pre-prompt
>
commands
prompt
end
pre-prompt
>
commands
prompt
post-commands
pre-prompt
(gdb)
prompt
where superfluous pre-prompt,prompt and commands annotations are output
(and an extra ">").
