Issue Fixed

RV32Q combination is no longer prohibited by the ISA Manual.

This restriction is introduced in binutils' RV32E support commit 7f99954970001cfc1b155d877ac2966d77e2c647. At that time, the latest ratified version of the RISC-V ISA Manual (version 2.2) stated that Q extension requires RV64IFD.

However, the next ratified version of the RISC-V ISA Manual (20190608-Base-Ratified) removed such limitation.
