The 'sync' instruction for MIPS was defined in MIPS-II as taking no operands. MIPS32 extended the define of 'sync' as taking an optional unsigned 5 bit immediate. This patch correct the definition of sync so that it is accepted with an operand of 0 or no operand for MIPS-II to MIPS-V, and a 5 bit unsigned immediate for MIPS32 and later revisions. Additionally a clear error is given when the MIPS32 version of sync is used when targeting pre MIPS32. This partially resolves PR/30714. Thanks to Daniel Sanders for reporting this issue!
