+/* Before including this file, you should define a macro:
+
+     DEF_PREDICTOR (ENUM, NAME, HITRATE)
+
+   This macro will be called once for each predictor.  The ENUM will
+   be of type `enum predictor', and will enumerate all supported
+   predictors.  The order of DEF_PREDICTOR calls is important, as
+   in the first match combining heuristics, the predictor appearing
+   first in this file will win.
+
+   NAME is used in the debugging output to determine predictor type.
+
+   HITRATE is the probability that edge predicted by predictor as taken
+   will be really taken (so it should be always above
+   REG_BR_PROB_BASE / 2).  */
