* s390x/tcg: fix and optimize SPX (SET PREFIX)David Hildenbrand2021-09-061-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | We not only invalidate the translation of the range 0x0-0x2000, we also invalidate the translation of the new prefix range and the translation of the old prefix range -- because real2abs would return different results for all of these ranges when changing the prefix location. This fixes the kvm-unit-tests "edat" test that just hangs before this patch because we end up clearing the new prefix area instead of the old prefix area. While at it, let's not do anything in case the prefix doesn't change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FP-to-integer conversion instructions need to set CC 3 whenever a "special case" occurs; this is the case whenever the instruction also signals the IEEE invalid exception. (See e.g. figure 19-18 in the Principles of Operation.) However, qemu currently will set CC 3 only in the case where the input was a NaN. This is indeed one of the special cases, but there are others, most notably the case where the input is out of range of the target data type. This patch fixes the problem by switching these instructions to the "static" CC method and computing the correct result directly in the helper. (It cannot be re-computed later as the information about the invalid exception is no longer available.) This fixes a bug observed when running the wasmtime test suite under the s390x-linux-user target.

Also add the dependencies of new facilities and as a fix for z15 add a dependency from S390_FEAT_VECTOR_PACKED_DECIMAL_ENH to S390_VECTOR_PACKED_DECIMAL.
