C Itanium: ?
|
||||
C Itanium 2: 1.25
|
||||
|
||||
C This code is scheduled deeply since the plain shift instructions shr and shl
|
||||
C have a latency of 4 (on Itanium) or 3 (on Itanium 2). Poor scheduling of
|
||||
C these instructions cause a 10 cycle replay trap on Itanium.
|
||||
|
||||
C The ld8 scheduling should probably be decreased to make the function smaller.
|
||||
C Good lfetch will make sure we never stall anyway.
|
||||
|
||||
C We should actually issue the first ld8 at cycle 0, and the first BSH/FSH pair
|
||||
C at cycle 2. Judicious use of predicates could allow us to issue more ld8's
|
||||
C in the prologue.
