Subject: Re: Regression due to tree loop opt / expand weirdness
Date: Wed, 06 Oct 2004 17:13:00 -0000 [thread overview]
Message-ID: <10410061645.AA13509@vlsi1.ultra.nyu.edu> (raw)
First of all, the above change is provably a no-op on ia64 since
the valid_pointer_mode implementation on ia64 is the default one,
which is exactly (mode != Pmode && mode != ptr_mode).
Please read what I wrote. On some ia64 systems (e.g., VMS), Pmode and
ptr_mode are both DImode but you need to support 32-bit pointers. On
those ia64 systems, target.valid_pointer_mode is overridden to allow both
SImode and DImode.
