I've been cleaning up some random branches and found this,
dating from mid-2017(!) My memory is that I wrote this going
into some softfreeze and then failed to do anything with it
once development opened again. Oops.
The major change is to handle ILEN via TCG unwinding, so that
we don't have to Just Know about the ILEN (the majority of the
calls to s390_program_interrupt use constants), or re-read from
memory (which gets EX wrong).

If, somehow, the psw_addr is out of range, truncate early
rather than after we get into gen_intermediate_code.

Use ILEN_UNWIND to signal that we have in fact that
cpu_restore_state will have been called by the time
we arrive in do_program_interrupt.

value of ilen immediately available.

This is no longer used, and many of the existing uses -- particularly
within hw/s390x -- seem questionable.

From: Richard Henderson @ 2019-04-01 10:29 UTC (permalink / raw)
To: qemu-devel; +Cc: david, cohuck, qemu-s390x
Replace all uses of s390_program_interrupt within files
that are marked CONFIG_TCG. These are necessarily tcg-only.
This lets each of these users benefit from the QEMU_NORETURN
attribute on tcg_s390_program_interrupt.
