target/s390x: fix CSST decoding and runtime alignment check CSST is defined as: C(0xc802, CSST, SSF, CASS, la1, a2, 0, 0, csst, 0) It means that the first parameter is handled by in1_la1(). in1_la1() fills addr1 field, and not in1. Furthermore, when extract32() is used for the alignment check, the third parameter should specify the number of trailing bits that must be 0. For FC these numbers are: FC=0 (word, 4 bytes): 2 FC=1 (double word, 8 bytes): 3 FC=2 (quad word, 16 bytes): 4 For SC these numbers correspond to the size: SC=0: 0 SC=1: 1 SC=2: 2 SC=3: 3 SC=4: 4 Signed-off-by: Pavel Zbitskiy <pavel.zbitskiy@gmail.com> Message-Id: <20180821025104.19604-4-pavel.zbitskiy@gmail.com> Reviewed-by: David Hildenbrand <david@redhat.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com> 2018-08-21 04:51:00 +02:00			`TESTS+=csst`
target/s390x: fix IPM polluting irrelevant bits Suppose psw.mask=0x0000000080000000, cc=2, r1=0 and we do "ipm 1". This command must touch only bits 32-39, so the expected output is r1=0x20000000. However, currently qemu yields r1=0x20008000, because irrelevant parts of PSW leak into r1 during program mask transfer.
