basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
* 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.
* inflow.c (initialize_inflow): Set tflags_ours correctly.
