◆ parseArchString()

Parse RISC-V ISA info from arch string.

If IgnoreUnknown is set, any unrecognised extension names or extensions with unrecognised versions will be silently dropped, except for the special case of the base 'i' and 'e' extensions, where the default version will be used (as ignoring the base is not possible).

◆ parseFeatures()

◆ parseNormalizedArchString()

Parse RISC-V ISA info from an arch string that is already in normalized form (as defined in the psABI).

Unlike parseArchString, this function will not error for unrecognized extension names or extension versions.
