[Qemu-devel] [PATCH for-4.1 0/6] target/s390x: Clean up tcg exceptions

[Richard Henderson]

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).

  target/s390x: Truncate 32-bit psw_addr before creating TB
  target/s390x: Add ilen to unwind data
  target/s390x: Use ilen from unwind in tlb_fill
  target/s390x: Remove ilen parameter from tcg_s390_program_interrupt
  target/s390x: Remove ilen parameter from s390_program_interrupt
  target/s390x: Use tcg_s390_program_interrupt in TCG helpers
