  No, absolutely not.  GILA is a general filter that has overall control over
which forms of addressing modes used to address memory may be generated in RTL.

http://gcc.gnu.org/onlinedocs/gccint/Addressing-Modes.html

  Hmm, I must have been looking at a slightly outdated build of the docs;
according to that page it's been deprecated on HEAD in favour of the hook
TARGET_LEGITIMATE_ADDRESS_P.  You'll need to check the particular sources
you're using, that must be a fairly recent change(*).


    cheers,
