It took me a minute to work out why we need both of these macros. I guess this one is just the same as EXPORT_ASSEMBLY_EXPRESSION(name, name, val) but without a name collision? That makes me think maybe we should use {} around the definition below?

We might want the names available in C++, maybe, and the invoking source could, in principle, choose to put things in scope to hide them if desired, but because these are otherwise at top-level, just using {} doesn't do the trick, eliciting "expected unqualified-id" errors from the compiler.

This could be a separate PR but these constants are needed in error handlers so we should make them more publicly available in the SDK.

This is a public heading (and this is why I don't like abbreviations in names of things: priv is short for 'privileged spec' not 'private').

I guess there's nothing stopping users from include priv/riscv.h it just seems a bit weird. At any rate we should do this in relevant places in the examples/tests.

These are not really "trusted stack", and we're about to have some more. While here, tweak a comment as per Robert's suggestion. Co-authored-by: Robert Norton <[email protected]>

Pull yet more out of #320. Thanks to @rmn30 for the suggestion to make these self-check a la
