--- Comment #7 from Alexander Ivchenko <aivchenk at gmail dot com> --- Do we have any documentation that states how many registers can be used in inline assembler for a particular arch and optset? "almost all" is not good enough for that. If the user code that worked in 4.8 correctly is now broken for 4.9, we better need to respect the user and document it properly.
