[PATCH] more x86-64 corrections
Fri Jul 23 14:34:00 GMT 2004
I'm not happy with that, but then let's leave this hunk out. However,
your change to revert to allow the segment overrides is then incomplete:
You either allow them all (cs,ds,es,fs,gs,ss), or you disallow all that
are pointless (cs,ds,es,ss). Or, as I indicated, you suppress their use
as segment override elsewhere, thus *only* allowing them as branch
prediction hints (but for a standalone prefix I can't imagine how one
would do that correctly). Jan

Nick, please don't apply this patch. It is wrong for Intel EM64T.
Jan, please bootstrap gcc 3.4.1 with -mtune=nocona on x86-64 and let
us know how it goes.
