Summary: The type of Imm in MipsDisassembler.cpp was incorrect since SignExtend64 return int64_t type.As per the MIPSr6 doc ,the offset is added to the address of the instruction following the branch (not the branch itself), to form a PC-relative effective target address hence “4” is added to the offset. The offset of some test case are update to reflect the changes due to “ + 4 ” offset and new test case for negative offset are added.
