I'm not well acquainted with SSE, and only so-so with x87, so pretty much I'm reading them for higher-level issues with tooling compatibility (like the concerns I already raised and looked up and seem to have resolved about x87 constraints and non-GCC compilers) and logic, then planning to apply and test them. I think being aware of non-obvious mistake modes that have already been found would be a lot more useful than staring at things, especially if the bugs you've found are in subtleties of the insn behavior or constraint behavior.
