We are currently looking for a high level language that
contains constructs which optimize jumps at the machine
code level. We are also interested in modifying "C" to
include such constructs.
As an example,
if (A>B) /*mostly*/ { }
else { }
or
if (A>B) { }
else /*mostly*/ { }
with the /*mostly*/ indicating which flow the programmer
thinks would occur more often.
We may then optimize the code to use the various delayed
and immediate jumps which the chip supports to get the
best results most of the time, without going to the
assembly level of programming.
I would appreciate any help or suggestions on this
subject.
