John Gilmore 2268d61946 Avoid longjmp()-catching compilation errors in cross-ports.
* doc/gdbint.texinfo:  Update GET_LONGJMP_TARGET, L_SET doc.
* irix4-nat.c, mips-nat.c (JB_ELEMENT_SIZE, get_longjmp_target):
Move from mips-tdep.c and tm-{irix3,mips}.h.
* mips-nat.c:  Remove a bunch of code that was ifdef'd out of
native MIPS ports.
* nm-irix3.h, nm-mips.h (GET_LONGJMP_TARGET):  Move from tm-irix3.h
and tm-mips.h.

Stu Grossman dac4929a6d * mips-tdep.c, mipsread.c, tm-mips.h: Get rid of ".gdbinfo."
symbol.  #define MIPS_EFI_SYMBOL_NAME instead.  Use different
value so that demangler won't be invoked.  This greatly speeds up
stepping.
* mips-tdep.c (mips_pop_frame):  Rewrite handling of
linked_proc_info so that it properly deallocates the appropriate
item after it is done with it instead of before.
* Don't pass bogus frame pointer to create_new_frame().  Just
leave it as zero so that lower level code will figure out the
correct value.

John Gilmore 0f552c5fc6 * buildsym.c (scan_file_globals): Beware the null file.
Fix from Jim Williams.

Fred Fish 5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
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.)

John Gilmore 361bf6eee5 Minor bug fixes from BSD Net2 gdb:
* 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.
