1177    NOTE:
1178    1. MIPS DSP ASE includes 4 accumulators ($ac0 - $ac3).  $ac0 is the pair
1179    of original HI and LO.  $ac1, $ac2 and $ac3 are new registers, and have
1180    the same structure as $ac0 (HI + LO).  For DSP instructions that write or
1181    read accumulators (that may be $ac0), we add WR_a (WR_HILO) or RD_a
1182    (RD_HILO) attributes, such that HILO dependencies are maintained
1183    conservatively.
1184
1185    2. For some mul. instructions that use integer registers as destinations
1186    but destroy HI+LO as side-effect, we add WR_HILO to their attributes.
1187
1188    3. MIPS DSP ASE includes a new DSP control register, which has 6 fields
1189    (ccond, outflag, EFI, c, scount, pos).  Many DSP instructions read or write
1190    certain fields of the DSP control register.  For simplicity, we decide not
1191    to track dependencies of these fields.
1192    However, "bposge32" is a branch instruction that depends on the "pos"
1193    field.  In order to make sure that GAS does not reorder DSP instructions
1194    that writes the "pos" field and "bposge32", we add DSP_VOLA (INSN_TRAP)
