/*
 * Assembler for our personal ISA.

 * TODO: add Line class that represents each line
 *
 * Example for source code:
 *
 *    ld r1, 0xabad
 *    ldu r1, 0x1dea
 *    ld r10, $whatever
 *    jrl r10
 *    hl
 *   .whatever:
 *    mov r5, r1
 *    jr r15
 *
 *  We have decoding from source code to an abstract representation of it by line
 *  and by relations between variables.
