2021-10-13s390x: sigp: Force Set Architecture to return Invalid ParameterEric Farman
According to the Principles of Operation, the SIGP Set Architecture order will return Incorrect State if some CPUs are not stopped, but only if the CZAM facility is not present. If it is, the order will return Invalid Parameter because the architecture mode cannot be changed. Since CZAM always exists when S390_FEAT_ZARCH exists, which in turn exists for every defined CPU model, we can simplify this code.

2021-10-07target/riscv: Set mstatus_hs.[SD|FS] bits if Clean and V=1 in mark_fs_dirty()Frank Chang
When V=1, both vsstauts.FS and HS-level sstatus.FS are in effect. Modifying the floating-point state when V=1 causes both fields to be set to 3 (Dirty). However, it's possible that HS-level sstatus.FS is Clean and VS-level vsstatus.FS is Dirty at the time mark_fs_dirty() is called when V=1. We can't early return for this case because we still need to set sstatus.FS to Dirty according to spec.

2021-10-07target/riscv: Remove RVB (replaced by Zb[abcs])Philipp Tomsich
With everything classified as Zb[abcs] and pre-0.93 draft-B instructions that are not part of Zb[abcs] removed, we can remove the remaining support code for RVB. Note that RVB has been retired for good and misa.B will neither mean 'some' or 'all of' Zb*: https://lists.riscv.org/g/tech-bitmanip/message/532 Signed-off-by: Philipp Tomsich <philipp.tomsich@vrull.eu> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Message-id: 20210911140016.834071-16-philipp.tomsich@vrull.eu Signed-off-by: Alistair Francis <alistair.francis@wdc.com>
2021-10-07target/riscv: Add zext.h instructions to Zbb, removing pack/packu/packhPhilipp Tomsich
The 1.0.0 version of Zbb does not contain pack/packu/packh. However, a zext.h instruction is provided (built on pack/packh from pre-0.93 draft-B) is available. This commit adds zext.h and removes the pack* instructions. Note that the encodings for zext.h are different between RV32 and RV64, which is handled through REQUIRE_32BIT.

2021-10-07target/riscv: Add rev8 instruction, removing grev/greviPhilipp Tomsich
The 1.0.0 version of Zbb does not contain grev/grevi. Instead, a rev8 instruction (equivalent to the rev8 pseudo-instruction built on grevi from pre-0.93 draft-B) is available. This commit adds the new rev8 instruction and removes grev/grevi. Note that there is no W-form of this instruction (both a sign-extending and zero-extending 32-bit version can easily be synthesized by following rev8 with either a srai or srli instruction on RV64) and that the opcode encodings for rev8 in RV32 and RV64 are different.
