7 title: RISC-V ISA extensions
15   RISC-V has a large number of extensions, some of which are "standard"
16   extensions, meaning they are ratified by RISC-V International, and others
17   are "vendor" extensions.
23   The properties for standard extensions therefore map to their originally
24   ratified states, with the exception of the I, Zicntr & Zihpm extensions.
44       Zicntr, Zicsr, Zifencei and Zihpm extensions and thus "i"
