+	* gencode.c (build_instruction): For "ppac5" use unsigned
+ 	arrithmetic so that the sign bit doesn't smear when right shifted.
+	(build_instruction): For "pdiv" perform sign extension when
+ 	storing results in HI and LO.
+	(build_instructions): For "pdiv" and "pdivbw" check for
+ 	divide-by-zero.
+	(build_instruction): For "pmfhl.slw" update hi part of dest
+ 	register as well as low part.
+	(build_instruction): For "pmfhl" portably handle long long values.
+	(build_instruction): For "pmfhl.sh" correctly negative values.
+  	Store half words 2 and three in the correct place.
+	(build_instruction): For "psllvw", sign extend value after shift.

+	* gencode.c (type_for_data_len): For 32bit operations concerned
+ 	with overflow, perform op using 64bits.
+	(build_instruction): For PADD, always compute operation using type
+ 	returned by type_for_data_len.
+	(build_instruction): For PSUBU, when overflow, saturate to zero as
+ 	actually underflow.
