/*TempleOS has a feature that allows
|
|
access to bytes and words of larger
|
|
ints.
|
|
|
|
See $LK,"U64i union",A="FF:::/Kernel/KernelA.HH,U64i union"$.
|
|
|
|
The versions with "i" are internal data types.
|
|
Use "I64" instead of "U64i" and you
|
|
will have access to subbytes and
|
|
subwords.
|
|
|
|
Unfortunately, byte access causes the
|
|
compiler to not use a reg for the
|
|
variable.
|
|
|
|
See $LK,"::/Demo/Lectures/FixedPoint.HC"$.
