I just built a VAX version of gdb+ V2.8.0 and am running under 4.3 BSD.

No matter how many routines down I am, gdb only seems to know about the
current stack frame:

	'bt' displays only a level 0 frame,
	'up' refuses to work,
	etc.
	
Has anybody else run into this problem?

Or did I just screw up when I built gdb?

Thanks.

I've brought up gdb+ 2.8.0 on a vax running Ultrix 3.0.
This is a bug in m-vax.h, I think.  Here are the diffs:

*** m-vax.h	Mon Dec 12 17:54:59 1988
--- m-vax.h.BAK	Mon Dec 12 17:24:15 1988
***************
*** 218,224
  
  /* Define other aspects of the stack frame.  */
  
! #define FRAME_SAVED_PC(frame, ignore) (read_memory_integer (frame + 16, 4), 0)
  
  /* Cannot find the AP register value directly from the FP value.
     Must find it saved in the frame called by this one, or in the AP register

In addition, when I compiled expread.y with yacc, I got 101 shift/reduce
conflicts, and 1 reduce/reduce conflict.  I've modified the grammar
so that it compiles with only 1 shift/reduce conflict and 1 reduce/reduce
conflict.  Those relate to C++ features that I haven't figured out yet.
I need to check my fixes though, so no posting yet.
