2022-01-08target/riscv: array for the 64 upper bits of 128-bit registersFrédéric Pétrot
The upper 64-bit of the 128-bit registers have now a place inside the cpu state structure, and are created as globals for future use.

2022-01-08target/riscv: additional macros to check instruction supportFrédéric Pétrot
Given that the 128-bit version of the riscv spec adds new instructions, and that some instructions that were previously only available in 64-bit mode are now available for both 64-bit and 128-bit, we added new macros to check for the processor mode during translation. Although RV128 is a superset of RV64, we keep for now the RV64 only tests for extensions other than RVI and RVM.

2021-12-20target/riscv: rvv-1.0: add evl parameter to vext_ldst_us()Frank Chang
Add supports of Vector unit-stride mask load/store instructions (vlm.v, vsm.v), which has: evl (effective vector length) = ceil(env->vl / 8). The new instructions operate the same as unmasked byte loads and stores. Add evl parameter to reuse vext_ldst_us().

2021-12-20target/riscv: rvv-1.0: trigger illegal instruction exception if frm is not validFrank Chang
If the frm field contains an invalid rounding mode (101-111), attempting to execute any vector floating-point instruction, even those that do not depend on the rounding mode, will raise an illegal instruction exception. Call gen_set_rm() with DYN rounding mode to check and trigger illegal instruction exception if frm field contains invalid value at run-time for vector floating-point instructions.
