Special Register
2.1 General Registers
The general registers are a set of 32 registers with 32-bit width. Of these registers %r0 to %r3 can be
used as general registers, but they do have special functions pre-assigned by the system. Registers
%r4 to %r31 can be used freely. Contents are undefined after reset.
