re: Building GLibc on x86_64 (ch. 6)

Well, following your advise I changed kernel. This what I got:

make[2]: [/sources/glibc-build/posix/annexc.out] Error 1 (ignored)
make[2]: *** [/sources/glibc-build/rt/tst-cpuclock2.out] Error 1
make[1]: *** [rt/tests] Error 2
make[2]: *** [/sources/glibc-build/elf/tst-xmmymm.out] Error 1
make[1]: *** [elf/tests] Error 2
make: *** [check] Error 2

So, this resaults shows that tst-rwlock errors depends on kernel and tst-xmmymm.out error is not. My tst-xmmymm.out file shows next:

root:/sources/glibc-build# cat elf/tst-xmmymm.out
dl-minimal.os needed for __GI___assert_fail
dl-lookup.os needed for _dl_lookup_symbol_x
dl-profile.os needed for _dl_mcount_internal
dl-trampoline.os needed for _dl_x86_64_restore_sse
rtld-mmap.os needed for __mmap
dl-misc.os needed for _dl_dprintf
rtld-_exit.os needed for _exit
rtld-memcpy.os needed for memcpy
rtld-memset.os needed for memset
dl-scope.os needed for _dl_scope_free
dl-error.os needed for _dl_signal_cerror
rtld-stpcpy.os needed for stpcpy
rtld-strcmp.os needed for strcmp
rtld-strcpy.os needed for strcpy
rtld-strlen.os needed for strlen
rtld-fxstat.os needed for __GI___fxstat64
rtld-close.os needed for __close
rtld-write.os needed for __libc_write
rtld-llseek.os needed for __lseek
rtld-munmap.os needed for __munmap
rtld-open.os needed for __open
rtld-profil.os needed for __profil
rtld-prof-freq.os needed for __profile_frequency
rtld-memcmp.os needed for memcmp
rtld-getpid.os needed for __getpid
rtld-__longjmp.os needed for __longjmp
rtld-setjmp.os needed for __sigsetjmp
rtld-mempcpy.os needed for mempcpy
rtld-setitimer.os needed for __setitimer
rtld-sigaction.os needed for __sigaction

object files needed: dl-runtime.os dl-minimal.os dl-lookup.os dl-profile.os dl-trampoline.os rtld-mmap.os dl-misc.os rtld-_exit.os rtld-memcpy.os rtld-memset.os dl-scope.os dl-error.os rtld-stpcpy.os rtld-strcmp.os rtld-strcpy.os rtld-strlen.os rtld-fxstat.os rtld-close.os rtld-write.os rtld-llseek.os rtld-munmap.os rtld-open.os rtld-profil.os rtld-prof-freq.os rtld-memcmp.os rtld-getpid.os rtld-__longjmp.os rtld-setjmp.os rtld-mempcpy.os rtld-setitimer.os rtld-sigaction.os

function memset in rtld-memset.os modifies xmm/ymm
function strlen in rtld-strlen.os modifies xmm/ymm
function memcmp in rtld-memcmp.os modifies xmm/ymm

As far as I see, the problem is in modification of xmm/ymm registers by this functions. If we'll fix it - we'll get a clear build. Or we must exclude this test if its failure doesn't important for future system.


P.S. Sorry about my english, absolutly no practice.
