...MOD/DIV are just other words for AND/ASR...

All times I use SET when working with hardware registers; so, I was curious about the generated code for MOD/DIV alternative A simple test for extracting some bits from a 16 bits value     a := 2345H;     b := a DIV 100H MOD 7; Generate : 10    40002345    MOV    R0    R0    9029 11    A0D00000    STR    R0    SB    0 12    80D00000    LDR    R0    SB    0 13    40020008    ASR    R0    R0    8 14    400B0007    DIV    R0    R0    7 15    20000000    MOV'    R0    R0    R0 16    A0D00004    STR    R0    SB    4 I forget something ?
