The primary options are: [^extend]: Prefix opcode space **must** be reserved in advance to do so, in order to avoid the catastrophic binary-incompatibility mistake made by RISC-V RVV and ARM SVE/2 [^likeext001]: SVP64-Single is remarkably similar to the "bit 1" of EXT001 being set to indicate that the 64-bits is to be allocated in full to a new encoding, but in fact it still embeds v3.0 Scalar operations. +[^pseudorewrite] elwidth overrides does however mean that all SFS / SFFS pseudocode will need rewriting to be in terms of XLEN. This has the indirect side-effect of automatically making a 32-bit Scalar Power ISA Specification possible, as well as a future 128-bit one (Cross-reference: RISC-V RV32 and RV128) -- 2.30.2
