Fast 32-bit and 16-bit Roll And Shift Functions - Keil Shell V1....

8051 assembly language functions, but are provided in a Keil
shell which will be especially convenient to those using C51,
but are otherwise general purpose. A Keil C51 test harness is
also provided.

Works really well and is fast

I used fast_long_roll in an MD5 function and it works a treat. A significant speed increase.

Very useful, genuinely fast

Author sent 32 roll function to me some time ago as part of optimisations for MD5. This made a significant difference to the run time for the hashing algorithm.
