a8172eea3d * mips-tdep.c (heuristic_proc_start): if we walk the pc into the fence
post without finding the enclosing function, then print a warning.

c2a0f1cb8e * remote-mips.c: New file; implements MIPS remote debugging
protocol.
	* config/idt.mt: New file; uses remote-mips.c
	* configure.in (mips-idt-ecoff): New target; uses idt.mt.

	* mips-tdep.c (mips_fpu): New variable; controls use of MIPS
	floating point coprocessor.
	(mips_push_dummy_frame): If not mips_fpu, don't save floating
	point registers.
	(mips_pop_frame): If not mips_fpu, don't restore floating point
	registers.
	(_initialize_mips_tdep): New function; let the user reset mips_fpu
	variable.
	* tm-mips.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): If not
	mips_fpu, don't use fp0 as floating point return register.
	(FIX_CALL_DUMMY): If not mips_fpu, don't save floating point
	registers.

Also added remote-mips.c to .Sanitize file.

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.

* ultra3-nat.c (register_addr):  Move from ultra3-xdep.c.
(fetch_core_registers):  Fix bfd_seek arguments.

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.

a70dc8981b Mips native support. Decstation and iris4 have been tested.
Iris3 has not.

* mips-tdep.c (supply_gregset, fill_gregset, supply_fpregset,
  fill_fpregset): removed to irix4-nat.c
* mips-xdep.c: removed.
* irix4-nat.c, mips-nat.c, nm-irix3.h, nm-irix4.h, nm-mips.h: new
  files.
* procfs.c: include nm.h.
* xm-irix3.h (U_REGS_OFFSET, FETCH_INFERIOR_REGISTERS): removed.
* xm-irix4.h: bump copyright.
(U_REGS_OFFSET, FETCH_INFERIOR_REGISTERS, USE_PROC_FS,
PROC_NAME_FMT): removed.
* xm-mips.h (FETCH_INFERIOR_REGISTERS): removed.
* config/irix4.mh (XDEPFILES): removed procfs.o fork-child.o.
(NAT_FILE, NATDEPFILES): new macros for native support.
(CC): supply default compiler switches.
* config/irix3.mh (XDEPFILES): removed infptrace.o inftarg.o fork-child.o coredep.o.
(NAT_FILE, NATDEPFILES): new macros for native support.  Note that
irix3 is untested.
* config/decstation.mh (XDEPFILES): removed infptrace.o inftarg.o
  fork-child.o mips-xdep.o coredep.o.
  (NAT_FILE, NATDEPFILES): new macros for native support.

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

* stack.c (return_command):  Evaluate expression *before* popping
off the stack frames!  Fix inspired by Jim Williams.
(up_silently_command, down_silently_command):  No sel frame is error.

* defs.h (memcpy, memset):  Conditionalize decls on
#ifndef MEM_FNS_DECLARED, since DECstation differs.
(alloca):  Break out the STDC and non-STDC alloca cases, to make
it work on old preprocessors as well as "picky ANSI" ones.
* xm-mips.h (memcpy, memset):  Declare, and set MEM_FNS_DECLARED.

* mips-tdep.c (heuristic_proc_start):  Zero arg produces zero.
* utils.c (fputs_demangled):  Rename SLOP since DECstation system
header files define it!

62a469e129 * mips-tdep.c: include symfile.h and objfiles.h to fix
compilation errors.

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.)

* param-no-tm.h:  Change users to define TM_FILE_OVERRIDE instead.
* param.h, param-no-tm.h:  Removed.
* Update copyrights in all changed files.
* dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
solib.c, symtab.h, tm-umax.h, valprint.c:  Lint.
* tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
xm-merlin.h:  Avoid host include files in target descriptions.
* getpagesize.h:  Removed, libiberty copes now.

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.
