OK. So with the recent change for ia64, the experimental build shows no failures though 3 arches haven't been built (alpha, hppa, mips). You previously said hppa doesn't have an autobuilder for experimental. I believe the other two did build the previous version, but I can no longer find the buildd page that shows all the build log history so I can't verify that. Matthias asks: > did you check, that all gcc versions do build with the new version > on all architectures, and that the gcc testsuite doesn't show > regressions with the new version? will gcc continue to work, while > re-building mpfr and mpclib with the new gmp? What I have done is upload gmp to the experimental autobuilders. The GMP package build runs a comprehensive test suite that is passing on all the architectures available to the experimental autobuilders. This gives me some comfort that the code is reasonably sound. In addition, the fact that GMP 5 has been out for over a year gives me some reason to believe that upstream sources have been adapted to change in API. Clearly one should be mindful of the effect on GCC -- that's why I asked the question on debian-gcc. Do you have any specific concerns? Is there a GCC autobuilder suite that can do all these rebuilds? I will upload there. However, to ask me to manually try all combinations of architecture and GCC version is setting the bar too high, IMHO. So: what is the next step? Thanks, -Steve
