* breakpoint.c, target.h: Move defaults of watchpoint related
macros back to breakpoint.c. Required to get GDB compiling
on Solaris again.
Fri May 19 14:49:37 1995 J.T. Conklin <jtc@rtl.cygnus.com>
* defs.h (ATTR_FORMAT): New macro, expands to gcc's format
attribute when compiled by gcc.
* defs.h, language.h, monitor.h: Changed many function
declarations to use ATTR_FORMAT.
* breakpoint.c (delete_command); source.c (directory_command);
top.c (define_command): Changed call to query() that had too
many arguments.
* printcmd.c (address_info): Changed call to printf_filtered()
that had too many arguments.
Fri May 19 09:52:07 1995 Jim Kingdon (kingdon@lioth.cygnus.com)
* infrun.c (wait_for_inferior): Move assignments to stop_signal

/* OK, when we call objfile_relocate, we need to relocate breakpoints
too. breakpoint_re_set is not a good choice--for example, if
addr_string contains just a line number without a file name the
breakpoint might get set in a different file. In general, there is
no need to go all the way back to the user's string (though this might
work if some effort were made to canonicalize it), since symtabs and
everything except addresses are still valid.
Probably the best way to solve this is to have each breakpoint save
the objfile and the section number that was used to set it (if set
by "*addr", probably it is best to use find_pc_line to get a symtab
and use the objfile and block_line_section for that symtab). Then
objfile_relocate can call fixup_breakpoints with the objfile and
the new_offsets, and it can relocate only the appropriate breakpoints. */
