2020-02-28target/arm: Replace ARM_FEATURE_VFP4 with isar_feature_aa32_simdfmacRichard Henderson
All remaining tests for VFP4 are for fused multiply-add insns. Since the MVFR1 field is used for both VFP and NEON, move its adjustment from the !has_neon block to the (!has_vfp && !has_neon) block. Test for vfp of the appropraite width alongside the test for simdfmac within translate-vfp.inc.c. Within disas_neon_data_insn, we have already tested for ARM_FEATURE_NEON.

2020-02-21target/arm: Convert PMULL.8 to gvecRichard Henderson
We still need two different helpers, since NEON and SVE2 get the inputs from different locations within the source vector. However, we can convert both to the same internal form for computation. The sve2 helper is not used yet, but adding it with this patch helps illustrate why the neon changes are helpful.

These instructions shift left or right depending on the sign of the input, and 7 bits are significant to the shift. This requires several masks and selects in addition to the actual shifts to form the complete answer. That said, the operation is still a small improvement even for two 64-bit elements -- 13 vector operations instead of 2 * 7 integer operations.

2020-02-21target/arm: Add _aa32_ to isar_feature functions testing 32-bit ID registersPeter Maydell
Enforce a convention that an isar_feature function that tests a 32-bit ID register always has _aa32_ in its name, and one that tests a 64-bit ID register always has _aa64_ in its name. We already follow this except for three cases: thumb_div, arm_div and jazelle, which all need _aa32_ adding. (As noted in the comment, isar_feature_aa32_fp16_arith() is an exception in that it currently tests ID_AA64PFR0_EL1, but will switch to MVFR1 once we've properly implemented FP16 for AArch32.)

2019-12-16target/arm: Handle AArch32 CP15 trapping via HSTR_EL2Marc Zyngier
HSTR_EL2 offers a way to trap ranges of CP15 system register accesses to EL2, and it looks like this register is completely ignored by QEMU. To avoid adding extra .accessfn filters all over the place (which would have a direct performance impact), let's add a new TB flag that gets set whenever HSTR_EL2 is non-zero and that QEMU translates a context where this trap has a chance to apply, and only generate the extra access check if the hypervisor is actively using this feature.
