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