pub const CALL_REG: &str = "x64.call_reg";Expand description
What the instruction that calls an address in a register is called.
A different instruction rather than the same one with a different operand, which is what the machine says too: one carries the distance to somewhere in the program and takes a relocation, and the other carries the register the address is in and takes none. Sharing an opcode would mean an instruction whose bytes depend on whether a field beside it happens to be set.
