This is a bit tricky to reference/quote for commenting, when the patch
isn't inline...
I presume this struct is meant to alias the amd64 CONTEXT, but with
different fields based on how it is used in arm64ec? Up until Pc/Rip,
this is straightforward to follow, but the struct for float/xmm is
quite hard to see how it maps... Ok, after looking into
XMM_SAVE_AREA32 it seems more understandable.
Yes, it's a convenience on ARM64EC that you may reference context with
either AMD64 or ARM64 register names (where possible). This essentially
applies ARM64EC registers mapping to the context structure, see [1] for
details.
Thanks for reviews,
Jacek
