Hi Andy,
Say a mainline links with a math library that uses AMX without the
knowledge of the mainline.
Say the mainline is also linked with a userspace threading library
that thinks it has a concept of XSAVE area size.
Wouldn't the change in XCR0, resulting in XSAVE size change, risk
confusing the threading library?
thanks,
