[PATCH v2 0/7] s390x/tcg: Implement Vector-Enhancements Facility 2

[David Miller]

Implement Vector-Enhancements Facility 2 for s390x

resolves: https://gitlab.com/qemu-project/qemu/-/issues/738


    implements:
    VECTOR LOAD ELEMENTS REVERSED               (VLER)
    VECTOR LOAD BYTE REVERSED ELEMENTS          (VLBR)
    VECTOR LOAD BYTE REVERSED ELEMENT           (VLEBRH, VLEBRF, VLEBRG)
    VECTOR LOAD BYTE REVERSED ELEMENT AND ZERO  (VLLEBRZ)
    VECTOR LOAD BYTE REVERSED ELEMENT AND REPLICATE (VLBRREP)
    VECTOR STORE ELEMENTS REVERSED              (VSTER)
    VECTOR STORE BYTE REVERSED ELEMENTS         (VSTBR)
    VECTOR STORE BYTE REVERSED ELEMENTS         (VSTEBRH, VSTEBRF, VSTEBRG)
    VECTOR SHIFT LEFT DOUBLE BY BIT             (VSLD)
    VECTOR SHIFT RIGHT DOUBLE BY BIT            (VSRD)
    VECTOR STRING SEARCH                        (VSTRS)

    modifies:
    VECTOR FP CONVERT FROM FIXED                (VCFPS)
    VECTOR FP CONVERT FROM LOGICAL              (VCFPL)
    VECTOR FP CONVERT TO FIXED                  (VCSFP)
    VECTOR FP CONVERT TO LOGICAL                (VCLFP)
    VECTOR SHIFT LEFT                           (VSL)
    VECTOR SHIFT RIGHT ARITHMETIC               (VSRA)
    VECTOR SHIFT RIGHT LOGICAL                  (VSRL)
