Re: [MI400] Is there an easy way to scan for bits?

["Steve Richter" <srichter@xxxxxxxxxxxxx>]

Leaving out the omi, nmi factor, if the OMI C compiler is used it translates
the C code to MI correct ?  Then the trusty translator translates the MI IRP
code to risc code and optimizes it along the way.  Where would C get its
advantage from ?
