Execute this instruction.
| thd | Thread context | |
| [out] | nextp | index of the next instruction to execute. (For most instructions this will be the instruction following this one). Note that this parameter is undefined in case of errors, use get_cont_dest() to find the continuation instruction for CONTINUE error handlers. |
