30 * These macros represent the logical IDs of each multi-letter RISC-V ISA
31 * extension and are used in the ISA bitmap. The logical IDs start from
32 * RISCV_ISA_EXT_BASE, which allows the 0-25 range to be reserved for single
33 * letter extensions. The maximum, RISCV_ISA_EXT_MAX, is defined in order
34 * to allocate the bitmap and may be increased when necessary.
36 * New extensions should just be added to the bottom, rather than added
37 * alphabetically, in order to avoid unnecessary shuffling.
