MO_TLVP - On a symbol operand this indicates that the immediate is some TLS offset. This is the TLS offset for the Darwin TLS mechanism. |
| MO_TLVP_PIC_BASE |
MO_TLVP_PIC_BASE - On a symbol operand this indicates that the immediate is some TLS offset from the picbase. This is the 32-bit TLS offset for Darwin TLS in PIC mode. |

getMemoryOperandNo - The function returns the MCInst operand # for the first field of the memory operand.
If the instruction doesn't have a memory operand, this returns -1.
Note that this ignores tied operands. If there is a tied register which is duplicated in the MCInst (e.g. "EAX = addl EAX, [mem]") it is only counted as one operand.
