3 * Support for Cygwin 1.7. Improved support for Cygwin 1.5.
4 Contributed by Eric Blake.
8 * Support for platforms that follow POSIX:2008, not POSIX:2001.
9 * Support for MirBSD 10.
10 * Support for IRIX 5.3. Contributed by Eric Blake.
11 * On Linux platforms, libsigsegv now prefers the POSIX way of defining the
12 signal handler over than the traditional one, when both are supported.
13 As a consequence, on Linux/i386 and other Linux platforms, the type
14 'stackoverflow_context_t' is now typedefed to 'ucontext_t *' rather than
15 'struct sigcontext *'.
19 * sigsegv_leave_handler is changed. Previously it was a normal function with
20 no arguments. Now it is a function that take a non-returning continuation
21 function and three arguments for it as arguments.
22 Where you had code like
23 int my_handler(void* fault_address, int serious)
26 sigsegv_leave_handler();
31 void my_handler_tail(void* arg1, void* arg2, void* arg3)
36 int my_handler(void* fault_address, int serious)
39 #if LIBSIGSEGV_VERSION >= 0x0206
40 return sigsegv_leave_handler(my_handler_tail, arg, NULL, NULL);
42 sigsegv_leave_handler();
43 my_handler_tail(arg, NULL, NULL);
48 * sigsegv_leave_handler now works correctly on MacOS X.
49 * Support for 64-bit ABI on MacOS X 10.5.
50 * Support for building universal binaries on MacOS X.
51 * Improved distinction between stack overflow and other fault on NetBSD,
52 OpenBSD, FreeBSD, Linux, AIX, Solaris. Contributed by Eric Blake.
53 * GNU gnulib now has an autoconf macro for locating libsigsegv:
54 http://www.gnu.org/software/gnulib/MODULES.html#module=libsigsegv
58 * Support for MacOS X 10.5.
62 * Support for GCC 4 on more platforms.
63 * Added support for catching stack overflow on NetBSD.
64 * Improved support for catching stack overflow on Linux, Solaris:
65 Works also when /proc is not mounted or lacks read permissions.
69 * Support for GCC 4 on some platforms contributed by Paolo Bonzini.
70 * Support for MacOS X i386 contributed by Bruno Haible.
71 * Improved support for Woe32 contributed by Doug Currie.
75 * Support for new versions of MacOS X contributed by Paolo Bonzini.
76 * Improved support for AIX 5, contributed by Bruno Haible.
80 * Support for MacOS X contributed by Paolo Bonzini.
81 * Support for Cygwin contributed by Paolo Bonzini.
82 * Support for Linux/ia64 and Linux/hppa contributed by Bruno Haible.
83 * Support for OpenBSD/i386 contributed by Bruno Haible.
84 * Support for NetBSD/alpha contributed by Paolo Bonzini.
88 * Modernized infrastructure.
89 * Added support for catching stack overflow on AIX 4, HP-UX, and BeOS.
90 * Dropped support for NeXTstep.
91 * The function sigsegv_leave_handler() no longer restores the signal mask.
92 This must now be done by the calling handler (either through sigprocmask
93 or through siglongjmp).
97 * Support for HP-UX contributed by Paolo Bonzini.
101 * Catching stack overflow now works on some Unix systems:
102 - Linux 2.2.x with glibc-2.1,
