Bug ID: 50360
Summary: [X86] Back merge some of the znver3 model features to
znver1/znver2 models
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86

Now that Roman has been able to get the znver3 model into a decent state we
should investigate copying some of this to the older models.
At the very least we can improve the fpu-pipes of most instructions based off
what we've seen on znver3 samples, and copy them over if the AMD SoGs say that
they are the same for znver1/znver2.
