Re: Bug#611249: gcc-4.4: Fix PR44606 concerning powerpcspe architecture

Not sure, if the release team wants such kind of patches at this stage. At least the version in unstable didn't yet migrate. I won't do this update anyway, mostly offline until Feb 13.

Hi, the attached .debdiff fixes PR44606 [1], a register-allocation bug
that (seldomly) miscompiles floating point code in the unofficial
powerpcspe port [2].

This is a backport of commit 168347 from GCC svn [3].

The patch modifies debian/rules.patch to only apply the patch on
powerpcspe, so there should be no side-effects on other architectures.

I verified the patch to compile and be effective on a powerpcspe sid
installation running on a P2020RDB development board.

I guess the same patch should go into gcc-4.3 as well, going to post a
corresponding bug report in the next days.
