Correct cycle detection during dependency sorting
2011-08-16 Andreas Schwab <schwab@redhat.com>
[BZ #11724]
* elf/dl-deps.c (_dl_map_object_deps): Only assume cycle when
object is seen twice.
* elf/dl-fini.c (_dl_sort_fini): Likewise.
* elf/Makefile (distribute): Add tst-initorder2.c.
(tests): Add tst-initorder2.
(modules-names): Add tst-initorder2a tst-initorder2b
tst-initorder2c tst-initorder2d. Add rules to build them.
($(objpfx)tst-initorder2.out): New rule.
* elf/tst-initorder2.c: New file.
* elf/tst-initorder2.exp: New file.
2011-08-21 Ulrich Drepper <drepper@gmail.com>
* sysdeps/unix/sysv/linux/x86_64/gettimeofday.S: Removed.
