--- Comment #1 from Tsukasa OI <research_trasio at irq dot a4lg.com> --- I think this is not a bug. Note that, 'B' will not be a single extension (at least for now) [1] but multiple extensions with 'Zb*' names are be defined and ratified. For instance, upcoming RVA22U64 profile [2] considers following extensions mandatory: - Zba (address computation) - Zbb (basic bit manipulation) - Zbs (single-bit fiddling) and following extensions unsupported optional: - Zbc (carry-less multiply) - Zbkb (crypto-related subextension) - Zbkc (crypto-related subextension) - Zbkx (crypto-related subextension) Try using those extensions instead.
