gwr 4fea918e34 For completeness, fix the SunOS/sun3 sigtramp support too. 
(I had to change tm-m68k.h which affects tm-sun3.h also.)
 1998-01-14 18:51:06 +00:00
gwr 254db76f83 Define IN_SIGTRAMP() as nbsd_in_sigtramp(), which knows how to find 
the address of the signal trampoline on all NetBSD/m68k machines.
(Fixes PR bin/3391)
 1998-01-14 18:45:44 +00:00
gwr eba66671ed Define FRAME_SAVED_PC to use the common sigtramp_saved_pc() just like 
the i386 does.  The previous definition was a SunOS-specific hack,
and if that is really still needed somwhere, it can still be used
by defining sigtramp_saved_pc as m68k_sigtramp_saved_pc in the
target-specific tm.h file.  The common sigtramp_saved_pc() fucntion
uses SIGCONTEXT_PC_OFFSET to find the return PC (the best way).
Do not define SIG_PC_FP_OFFSET here.  (very machine-specific!)
 1998-01-14 18:42:05 +00:00
gwr 6cc4f2227c Add two new functions: 
m68k_sigtramp_saved_pc() - like the comon sigtramp_saved_pc, but
  uses SIG_PC_FP_OFFSET to find the saved PC (used for SunOS).
nbsd_in_sigtramp() - determine whether a PC value is within the
  signal trampoline, but do so WITHOUT hard-coding the address
  of the end of the stack (uses "__ps_strings" at run time).
  This allows a common gdb to work on all m68k. (yea!)

gwr 521ae36095 No longer need to include solib.h here. 1998-01-12 19:49:14 +00:00
gwr 85ec3a65c8 Uh... tabs vs spaces... 1998-01-12 16:22:01 +00:00
gwr 734fb3d7c0 Fix the comment that claims "only SunOS" needs this (referring to the 
extra initial SIGTRAP after ld.so finishes).  NetBSD needs it too.
 1998-01-12 16:21:14 +00:00
gwr c7f6e84cbe Ignore symbols of type N_WARNING (0x1e) on NetBSD. 1998-01-12 16:14:58 +00:00
gwr 98e7377438 OK, this file was pretty much completely wrong. I copied it from the 
SunOS version, but our shared libraries are not THAT much like SunOS.
In NetBSD a.out shared libraries, trampoline stubs have _DYNAMIC+n
as their symbol, so we can recognize them with strcmp.  We may also
need SKIP_TRAMPOLINE_CODE(pc) eventually, but doing that right takes
machine dependent code to lookup what the _DYNAMIC stub jumps to.
(gdb appears to work OK on a.out without SKIP_TRAMPOLINE_CODE)

jonathan 5438df9f2f Correct offset and size of register-copying code in fetch_inferior_registers() 
and set_inferior_regsiters() to match the split scalar/FP register  structs.
Based on fetch_core_registers.

Fixes some but not all of PR 4589.

ross 11751c2757 Once upon a time, someone must have done a global s/ALL/BASE/ while 
ignoring case and tokens, inventing the "hw_rei_stBASE" instruction. Undo.
