Yes, I mean a single macro that produces both the instruction and the CFI
pseudo-op to go with it.  This is the essential characteristic that makes
it an improvement for maintaining the code.  The main problem we have now
is that it's easy to write/modify plain assembly instructions and forget to
add or update the CFI to match.  A well-considered set of macros can solve
this without making it any harder for the average assembly programmer to
understand what each line of the source means intuitively.


Thanks,
Roland
