overridevirtual

Print the specified MCInst to the specified raw_ostream.

Address the address of current instruction on most targets, used to print a PC relative immediate as the target address. On targets where a PC relative immediate is relative to the next instruction and the length of a MCInst is difficult to measure (e.g. x86), this is the address of the next instruction. If Address is 0, the immediate will be printed.

Implements llvm::MCInstPrinter.
