Method to load an instruction into memory

s suffix for scalar registers

x suffix for vector registers

parses args

parses an int/bool option from the command line

<opcode> <rd>, <rs1>, <imm12>

JALR instruction is JALR rd, rs1, offset <=> rd = PC + 1, PC = rs1 + offset Therefore we can use it to jump to labels if rs1 = r0 That's why there are

Process read requests

Store

allows the user to override procedurally the bool options from the command line

users should query this in their main() and exit the program if true

This returns IData rather than Opcode because it can return a scalar version of the opcode if the input string is prefixed with "s."
