<div>
<pre>All x86 CPUs have very different costs/behaviours for vXi32 and vXi64 masked
stores, we need to split these classes so we can use them without so many
overrides.
def WriteVecMaskedStore : SchedWrite;
def WriteVecMaskedStoreY : SchedWrite;
should be:
def WriteVecMaskedStore32 : SchedWrite;
def WriteVecMaskedStore64 : SchedWrite;
def WriteVecMaskedStore32Y : SchedWrite;
def WriteVecMaskedStoreY64 : SchedWrite;
Similar to what we have for masked float vector stores:
def WriteFMaskedStore32 : SchedWrite;
def WriteFMaskedStore64 : SchedWrite;
def WriteFMaskedStore32Y : SchedWrite;
def WriteFMaskedStore64Y : SchedWrite;</pre>
