target/riscv: Consolidate RV32/64 32-bit instructions This patch removes the insn32-64.decode decode file and consolidates the instructions into the general RISC-V insn32.decode decode tree. This means that all of the instructions are avaliable in both the 32-bit and 64-bit builds. This also means that we run a check to ensure we are running a 64-bit softmmu before we execute the 64-bit only instructions. This allows us to include the 32-bit instructions in the 64-bit build, while also ensuring that 32-bit only software can not execute the instructions.

target/riscv: add vector stride load and store instructions Vector strided operations access the first memory element at the base address, and then access subsequent elements at address increments given by the byte offset contained in the x register specified by rs2. Vector unit-stride operations access elements stored contiguously in memory starting from the base effective address. It can been seen as a special case of strided operations.

target/riscv: accessors to registers upper part and 128-bit load/store Get function to retrieve the 64 top bits of a register, stored in the gprh field of the cpu state. Set function that writes the 128-bit value at once. The access to the gprh field can not be protected at compile time to make sure it is accessed only in the 128-bit version of the processor because we have no way to indicate that the misa_mxl_max field is const. The 128-bit ISA adds ldu, lq and sq. We provide support for these instructions. Note that (a) we compute only 64-bit addresses to actually access memory, cowardly utilizing the existing address translation mechanism of QEMU, and (b) we assume for now little-endian memory accesses.

target/riscv: accessors to registers upper part and 128-bit load/store Get function to retrieve the 64 top bits of a register, stored in the gprh field of the cpu state. Set function that writes the 128-bit value at once. The access to the gprh field can not be protected at compile time to make sure it is accessed only in the 128-bit version of the processor because we have no way to indicate that the misa_mxl_max field is const. The 128-bit ISA adds ldu, lq and sq. We provide support for these instructions. Note that (a) we compute only 64-bit addresses to actually access memory, cowardly utilizing the existing address translation mechanism of QEMU, and (b) we assume for now little-endian memory accesses.

This also means that we run a check to ensure we are running a 64-bit softmmu before we execute the 64-bit only instructions. This allows us to include the 32-bit instructions in the 64-bit build, while also ensuring that 32-bit only software can not execute the instructions.

target/riscv: add vector stride load and store instructions Vector strided operations access the first memory element at the base address, and then access subsequent elements at address increments given by the byte offset contained in the x register specified by rs2. Vector unit-stride operations access elements stored contiguously in memory starting from the base effective address. It can been seen as a special case of strided operations.

target/riscv: Consolidate RV32/64 32-bit instructions This patch removes the insn32-64.decode decode file and consolidates the instructions into the general RISC-V insn32.decode decode tree. This means that all of the instructions are avaliable in both the 32-bit and 64-bit builds. This also means that we run a check to ensure we are running a 64-bit softmmu before we execute the 64-bit only instructions. This allows us to include the 32-bit instructions in the 64-bit build, while also ensuring that 32-bit only software can not execute the instructions.
