Point of order!
The RISC-V C extension takes up 75% of the opcode space.
The 16 bit Thumb1 instructions take up 87.5% of the ARMv7 opcode space.
Not to mention predication taking up 92.75% of the classic ARMv1-ARMv6 instruction set.
RISC-V has comparatively twice as much "32 bit" opcode space as ARMv7, and 3.45x more than classic ARM A32.
