Detailed Description

Root for abstract assembly instructions.

Assemly instructions are composed of a string (the instruction itself) a` la printf, where

• "'s" designates a source register

• "'d" designates a destination register

• "'j" designates a destination (jump) label

and of three lists

• source registers

• destination registers

• destination labels

After instruction selection, the registers are mostly soft (or pseudo) registers, and register allocation replaces then with hard registers.
