This has me curious though...
The original patch had much more complicated changes to discourage
use of
these instructions conditional on TARGET_74K. This is a simpler
approach
and it's clearly a tuning matter so TUNE_74K rather than TARGET_74K is
appropriate.
Right.
*reads* Hunh. Ok. Weird though.
