Hello,Everyone!
Could you find some info about the following
problems I meet?
1 When I read the source code of Pro64,the comment said
that:
Loop unrolling is performed by: BB *CG_LOOP_Unroll(LOOP_DESCR *loop),
which
returns a new unrolled body if the loop is unrolled. It may also
create a
"remainder loop" in the prolog or epilog.
But I do not
found this function in Pro64.And another function
unroll_multi_BB never been
called in Pro64.I want to know whether this is
true.
2 In
Single_BB_Do_Loop_SWP,is unrolling also done?
3 Before unroll,the
whole loop converted to a single BB,is that
true?
Thanks!
With my best regards,
