Status of GCC 4.4 (Debian)
Given that GCC moved to stage 3 recently, I decided to build the Debian
archive to identify new issues before GCC 4.4 is released. I compiled
the entire Debian archive (just under 8000 packages that need to be
compiled) on x86_64, ia64 and powerpc, and about 1800 packages on arm
(EABI). I also wanted to test GCC on alpha, mips and sparc but ran
into compiler errors during bootstrap.
In total, I filed 28 new bugs and ran into 7 known issues. 64% of the
bugs I filed have already been fixed and many of those that are still
open have already received some attention. I'd like to thank the GCC
community for such an oustanding job dealing with incoming bug reports
and fixing compiler regressions.
Here's the complete list of issues I ran into:

The testing was done on an EM64T system donated to Debian by Intel and
hosted by Stephen Frost, an IA64 hosted by the Gelato Federation, an
IBM OpenPower hosted at the University of Augsburg and a Marvell 78x00
development board hosted by Voipio Riku.
