Enumeration Type Documentation

anonymous enum

Enumerator:

PPC970_First	PPC970_First - This instruction starts a new dispatch group, so it will always be the first one in the group.
PPC970_Single	PPC970_Single - This instruction starts a new dispatch group and terminates it, so it will be the sole instruction in the group.
PPC970_Cracked	PPC970_Cracked - This instruction is cracked into two pieces, requiring two dispatch pipes to be available to issue.
PPC970_Shift	PPC970_Mask/Shift - This is a bitmask that selects the pipeline type that an instruction is issued to.
PPC970_Mask
