5 * GCC defines register number like this:
6 * -----------------------------
7 * 0 - 7 are data registers R0-R7
8 * 8 - 15 are address registers P0-P7
9 * 16 - 31 dsp registers I/B/L0 -- I/B/L3 & M0--M3
10 * 32 - 33 A registers A0 & A1
11 * 34 - status register
12 * -----------------------------
14 * We follows above, except:
15 * 32-33 --- Low 32-bit of A0&1
16 * 34-35 --- High 8-bit of A0&1
