This series adds support for the "Vector enhancements facility" and bumps the qemu CPU model to a stripped-down z14. I tested most vector FP instructions by generating random instructions and vectors, comparing the result with results on actual hardware. I did not test instructions/instruction variants with (partial) undeterministic behavior and exception handling. Linux' also seems to boot/work fine with it. Howeever, while testing this series I noticed that Linux checks for the wrong facility bit - see [1]. I tested by temporarily faking availability of the "wrong" facility bit.

Mostly addressed feedback from Richard, a couple of bugfixes found while testing, and some simplifications/cleanups. - Rebased on top of Richard's softfloat rework Cc: qemu-s390x@nongnu.org Cc: Cornelia Huck Cc: Halil Pasic Cc: Christian Borntraeger Cc: Thomas Huth Cc: Richard Henderson Cc: Laurent Vivier David Hildenbrand (26): s390x/tcg: Fix FP CONVERT TO (LOGICAL) FIXED NaN handling s390x/tcg: Fix instruction name for VECTOR FP LOAD (LENGTHENED|ROUNDED) s390x/tcg: Simplify vop64_3() handling s390x/tcg: Simplify vop64_2() handling s390x/tcg: Simplify vfc64() handling s390x/tcg: Simplify vftci64() handling s390x/tcg: Simplify vfma64() handling s390x/tcg: Simplify vfll32() handling s390x/tcg: Simplify vflr64() handling s390x/tcg: Simplify wfc64() handling s390x/tcg: Implement VECTOR BIT PERMUTE s390x/tcg: Implement VECTOR MULTIPLY SUM LOGICAL s390x/tcg: Implement 32/128 bit for VECTOR FP (ADD|DIVIDE|MULTIPLY|SUBTRACT) s390x/tcg: Implement 32/128 bit for VECTOR (LOAD FP INTEGER|FP SQUARE ROOT) s390x/tcg: Implement 32/128 bit for VECTOR FP COMPARE * s390x/tcg: Implement 32/128 bit for VECTOR FP COMPARE (AND SIGNAL) SCALAR s390x/tcg: Implement 64 bit for VECTOR FP LOAD LENGTHENED s390x/tcg: Implement 128 bit for VECTOR FP LOAD ROUNDED s390x/tcg: Implement 32/128 bit for VECTOR FP PERFORM SIGN OPERATION s390x/tcg: Implement 32/128 bit for VECTOR FP TEST DATA CLASS IMMEDIATE s390x/tcg: Implement 32/128 bit for VECTOR FP MULTIPLY AND (ADD|SUBTRACT) s390x/tcg: Implement VECTOR FP NEGATIVE MULTIPLY AND (ADD|SUBTRACT) s390x/tcg: Implement VECTOR FP (MAXIMUM|MINIMUM) linux-user: elf: s390x: Prepare for Vector enhancements facility s390x/tcg: We support Vector enhancements facility s390x/cpumodel: Bump up QEMU model to a stripped-down IBM z14 GA2 hw/s390x/s390-virtio-ccw.c | 3 + include/elf.h | 7 + linux-user/elfload.c | 1 + target/s390x/cpu_models.c | 4 +- target/s390x/fpu_helper.c | 41 +- target/s390x/gen-features.c | 14 +- target/s390x/helper.h | 70 +- target/s390x/insn-data.def | 16 +- target/s390x/internal.h | 9 + target/s390x/translate_vx.c.inc | 633 ++++++++++++++---- target/s390x/vec_fpu_helper.c | 1079 ++++++++++++++++++++++--------- target/s390x/vec_helper.c | 22 + 12 files changed, 1428 insertions(+), 471 deletions(-) -- 2.31.1
