It is frequently required to obtain the highest order bit of an integral
type (long, int, short or char types).
- SDCC recognizes the following expression to yield the highest order bit
+ Also obtaining any other order bit is not uncommon.
+ SDCC recognizes the following expressions to yield the highest order bit
and generates optimized code for it, e.g.:
\layout Verse

\SpecialChar ~
-unsigned char hob;
+unsigned char hob1, aob1;
+\newline

+\SpecialChar ~

-hob = (gint >> 15) & 1;

-Variations of this case however will

- It is a standard C expression, so I heartily recommend this be the only
