+Currently unimplemented:
+* cast fp to bool
+* signed right shift
+
+Current bugs:
+* use of a cByte/cShort by setCC not first truncated or sign extended
+  (uByte r3 = 250, r3 + 100; setlt r3, 200 will get wrong result).
+* conditional branches assume target is within 32k bytes
+* large fixed-size allocas not correct
+
+Currently failing tests:
+* Regression
+* SingleSource
