You mention that some implementations disassemble the faulting
instruction to get at the operands.  I'm wondering if I could do this
with Linux's ucontext_t structure, containing fpregs and __fpregs_mem.
The data therein does not look intelligible yet, but presuming I
decipher it, won't this still be a portability nightmare across 12
arches?  Is there no somewhat simple abstraction here?

Take care,
