Debian's glibc maintainer told me that the glibc testsuite on SPARC has more failures on 32-bit than on 64-bit. Maybe we should look into trying to get some of these failures fixed first. CC'ing Adhemerval from glibc upstream who has done a lot of bug fixing on SPARC in glibc. It could be useful in this context if Gentoo could provide a small Gentoo SPARC LDOM running 32-bit userland for the GCC Compile Farm. This way upstream developers get easy access to a Gentoo SPARC instance to be able to reproduce issues like this. > When I read about https://sourceware.org/git/? > p=glibc.git;a=commit;h=b33e946fbb1659d2c5937c4dd756a7c49a132dff I thought that > this may solve the issue, but I rebuild my glibc in a chroot with that patch > and at least the fish testsuite hangs are unchanged. > > Has anyone a clue what's going on there? I know that there have been some stability issues with the Linux kernel on SPARC with older hardware like the UltraSPARC IIIi. The T5120 we have and newer machines seem to run relatively fine with a 64-bit userland. Adrian -- .''`.
