Hi,On MIPS R4000 CPU, LLAddr register is read-write, whereas on MIPS64 specification, it is read-only. Attached patch adds a new instruction flag (INSN_R4000), which is checked to know if register is writable.
Also, it changes the return format of the LLAddr register, which is defined as implementation-dependant in MIPS64, so it shouldn't hurt.
