The headings in this response are described under “Responses” on page 317.
ED-ADDR can be either 32 or 64 bits.
Response 5:
If a guest virtual address from the home address space cannot be converted to a
host real address, the translation process generates one of several exceptions,
identifying the first page that was not addressable. The responses are:
Vhexloc1 to hexloc2 nonaddressable storage
- protection exception
Vhexloc1 to hexloc2 nonaddressable storage
- addressing exception
Vhexloc1 to hexloc2 nonaddressable storage
- segment translation exception
Vhexloc1 to hexloc2 nonaddressable storage
- page translation exception
Vhexloc1 to hexloc2 nonaddressable storage
- translation specification exception
The operand Vhexloc1 is the starting address, and hexloc2 the ending address, of
the nonaddressable storage.
Response 6:
If a state entry that is neither a branch nor a program call is reached, the following
response is issued:
Vhexloc1 to hexloc2 are linkage stack
state entries that are not branch or program-call.
The operand Vhexloc1 is the starting address, and hexloc2 the ending address, of
the block of contiguous state entries in a linkage stack section that are not a branch
or a program call.
Response 7:
The linkage stack is empty.
is issued if the linkage stack is empty.
