+/* MIPS DSP ASE support.
+   NOTE:
+   1. MIPS DSP ASE includes 4 accumulators ($ac0 - $ac3).  $ac0 is the pair
+   of original HI and LO.  $ac1, $ac2 and $ac3 are new registers, and have
+   the same structure as $ac0 (HI + LO).  For DSP instructions that write or
+   read accumulators (that may be $ac0), we add WR_a (WR_HILO) or RD_a
+   (RD_HILO) attritubes, such that HILO dependences are maintained
+   conservatively.
+
+   2. For some mul. instructions that use integer registers as destinations
+   but destroy HI+LO as side-effect, we add WR_HILO to their attritubes.
+
+   3. MIPS DSP ASE includes a new DSP control register, which has 6 fields
+   (ccond, outflag, EFI, c, scount, pos).  Many DSP instructions read or write
+   certain fields of the DSP control register.  For simplicity, we decide not
+   to track dependences of these fields.
+   However, "bposge32" is a branch instruction that depends on the "pos"
+   field.  In order to make sure that GAS does not reorder DSP instructions
+   that writes the "pos" field and "bposge32", we add DSP_VOLA (INSN_TRAP)
+   attritube to those instructions that write the "pos" field.  */
