Hi!
This testcase tests unwinding through signal frames
(with or without alternate stack, with or without siginfo).
It passes on IA-32, ATM fails on IA-64 when using GCC unwinder.
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.
