+ * gencode.c (build_instruction): For "ppac5" use unsigned
+ arrithmetic so that the sign bit doesn't smear when right shifted.

+ 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.
