Type this from the DOS prompt:
info gcc "C Extensions" "Extended Asm"
(Note the quotes: they are important.)

These are called ``constraints''. One of the links from the above
section leads to the full list. If you want to get the list right
away, type this:
info gcc machine constraints
Btw, if you know that these are called ``constraints'', you should be
able to find it easily in the GCC manual using the `index-search'
command. Type "info gcc", then press `i', and type "constraints" and
hit [Enter] when Info prompts for a topic. This is a very powerful
command IMHO, as it leads you through all index entries which have the
string you enter as a substring. In the case in point, the very first
hit is what you want.
