The attached debdiff makes sid's eglibc (2.13-8) work on architecture powerpcspe. We have a few new test-case errors, that are not listed in debian/testsuite-checking/expected-results-powerpc-linux-gnu-libc :
bug-nextafter.out, Error 18 bug-nexttoward.out, Error 18 test-double.out, Error 1 test-fenv.out, Error 1 test-float.out, Error 1 test-idouble.out, Error 1 test-ifloat.out, Error 1 test-misc.out, Error 1 tst-setcontext-fpscr.o, Error 1 these complain about various details of the FPU, especially exception and overflow handling, rounding, slight deviations on results. I cannot find anything that looks like a real "bad" error, though. tst-setcontext-fpscr contains some assembly code and won't even compile in e500 mode. cheers, David -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
