the bug is in lines
1080 and 2237 of /opcodes/m32c-ibld.c
both for M32C_OPERAND_DSP_8_S24
the original line
value = ((((((USI) (value) >> (16))) | (((value) & (65280))))) |
(((EXTQISI (TRUNCSIQI (((value) & (255))))) << (16))));
must be
value = ((((((((USI) (value) >> (16)) & (255)))) | (((value) &
(65280))))) | (((EXTQISI (TRUNCSIQI (((value) & (255))))) << (16))));
the HiHi byte is not anded (cleared) in the original so is ored later with the
HiLo giving wrong result
