--- Comment #8 from Jorn Wolfgang Rennecke <amylaar at gcc dot gnu.org> 2012-11-05 02:32:35 UTC --- (In reply to comment #7) > In some sense, this seems like a hack which might be optimized by an > attribute processor. What about a way to mark length attributes as > variable? That would be nice, and pretty straightforward to code, but we seem short of generator program patches reviewers now. Note, I don't think there is any valid reason for the attribute processor to look inside a match_test; if it was something that the generators were supposed to understand, we should have rtl syntax for it.
