Hi,
I just wanted to compile gcc-4.0 to get a fortran 95 compiler and the
build fails on my ppc with
DEB_VERSION='4.0-0pre2'; export DEB_VERSION; \
debian/patches/powerpc-biarch.dpatch -patch -d
ouch, please edit debian/rules.defs and disable the biarch build for
powerpc.

Hi Jeff,
Note that recording tmp_1 = next_2 isn't particularly good either since
tmp_1 really isn't equivalent to next_2. It's

Hi Jeff,
I think so. :-)
I don't. :( I think it'll record tmp_1 = next_2, which is actually
wrong, even though it doesn't

Hi Jeff,
BTW, I may have a nice clean way to deal with this problem which doesn't
depend on us not walking the SSA_NAME_VALUE chain.

Hi Jeff,
Err, no. You're totally warping how the the equivalency code is meant
