s390x/tcg: check for addressing exceptions for RRBE, SSKE and ISKE

2021-09-06T14:24:05+00:00

Let's replace the ram_size check by a proper physical address space check (for example, to prepare for memory hotplug), trigger addressing exceptions and trace the return value of the storage key getter/setter. Provide an helper mmu_absolute_addr_valid() to be used in other context soon. Always test for "read" instead of "write" as we are not actually modifying the page itself.

target/s390x: Fix CC set by CONVERT TO FIXED/LOGICAL

2021-07-07T11:57:25+00:00

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.

s390x/tcg: Implement VECTOR FP (MAXIMUM|MINIMUM)

2021-06-21T06:48:21+00:00

For IEEE functions, we can reuse the softfloat implementations. For the other functions, implement it generically for 32bit/64bit/128bit - carefully taking care of all weird special cases according to the tables defined in the PoP.
