Update.
2003-12-18 Ulrich Drepper <drepper@redhat.com> * tst-eintr1.c: Better error messages. * Makefile (tests): Add tst-eintr2. * tst-eintr2.c: New file. 2003-12-18 Jakub Jelinek <jakub@redhat.com> * Makefile (tests): Add tst-cancel21 and tst-cancelx21. (CFLAGS-tst-cancelx21.c): Set. * tst-cancel21.c: New test. * tst-cancelx21.c: New test. * unwind.c (FRAME_LEFT): Add adj argument. Subtract it from each comparison operand. (unwind_stop): Use _JMPBUF_CFA_UNWINDS_ADJ macro instead of _JMPBUF_CFA_UNWINDS. Adjust FRAME_LEFT invocations. * pt-longjmp.c: Include jmpbuf-unwind.h. (__pthread_cleanup_upto): Use _JMPBUF_UNWINDS_ADJ macro instead of _JMPBUF_UNWINDS. Adjust compared pointers. * init.c (__pthread_initialize_minimal_internal): Initialize pd->stackblock_size. * sysdeps/pthread/jmpbuf-unwind.h: Removed. * sysdeps/alpha/jmpbuf-unwind.h: New file. * sysdeps/i386/jmpbuf-unwind.h: New file. * sysdeps/powerpc/jmpbuf-unwind.h: New file. * sysdeps/s390/jmpbuf-unwind.h: New file. * sysdeps/sh/jmpbuf-unwind.h: New file. * sysdeps/sparc/sparc32/jmpbuf-unwind.h: New file. * sysdeps/x86_64/jmpbuf-unwind.h: New file. * sysdeps/ia64/jmpbuf-unwind.h: Include stdint.h. (_JMPBUF_CFA_UNWINDS): Remove. (_JMPBUF_CFA_UNWINDS_ADJ, _JMPBUF_UNWINDS_ADJ): Define. 2003-12-12 Jakub Jelinek <jakub@redhat.com> * Makefile (tests): Add tst-cancel20 and tst-cancelx20. (CFLAGS-tst-cancelx20.c): Set. * tst-cancel20.c: New test. * tst-cancelx20.c: New test.
