func hash
Hashes a virtual address into a hash table (real) offset.
Syntax
hash ( virtaddr )
The hash value can be added to the Hash table base real address (TR1) to determine the
real offset to the first PDIR entry.
Formal Declaration
hash:s32 ( virtaddr :ptr)
Parameters
virtaddr The virtual address that is to be hashed.
Virtaddr can be a short pointer, a long pointer, or a full logical code
pointer.
Examples
nmdat > wl pc
SYS $a.d87f8
nmdat > wl hash(pc)
$103c4
nmdat > dz tr1+hash(pc)
REAL $103c4 $ 00001b00
nmdat > dz tr0+1b00,4
REAL $0061dd00 $ 80000000 0000000a 000d8000 82800000
