Introduce the GET_FEATURE_REG_SET() and GET_FEATURE_REG_EQU()
macros to check if an instruction set is supported by a CPU
using CP0 read-only bits (instead of QEMU insn_flags which
is not always coherent - we might remove it soon).
Use these macros to test for MSA ASE and Release 6.
Update the ELF HWCAP bits and set the Loongson instructions
so we can run 2F/3E userland binaries.
Supersedes: <20201201083951.2745111-1-f4bug@amsat.org>
Philippe Mathieu-Daudé (6):
linux-user/elfload: Move GET_FEATURE macro out of get_elf_hwcap() body
linux-user/elfload: Rename MIPS GET_FEATURE() as GET_FEATURE_INSN()
linux-user/elfload: Introduce MIPS GET_FEATURE_REG_SET() macro
linux-user/elfload: Introduce MIPS GET_FEATURE_REG_EQU() macro
linux-user/elfload: Update HWCAP bits from linux 5.7
linux-user: Add support for MIPS Loongson 2F/3E
