Bug report for gdb

Version: GDB 4.6

Machine: Sun4 running SunOS 4.1.2

GDB was compiled with GCC 2.2.2.

test file:
------------------------------ cut here ------------------------------
/* unimp.s */
.text
	unimp 17
------------------------------ cut here -----------------------------

compiled with:
/usr/bin/as unimp.s -o unimp.o

input script:

bash$ gdb unimp.o

unimp.o has no symbol-table

(gdb) x/i
0x0:	unimp n
(gdb) quit

What's wrong:

It doesn't print the operand of unimp.

My explanation:

Argument `n' indicating 22 bit immediate value is not implemented in
the switch in sparc-pinsn.c so the arguments gets printed as `n'.

My patch:
