From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/cleanup-5.c | 53 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cleanup-5.c (limited to 'gcc/testsuite/gcc.dg/cleanup-5.c') diff --git a/gcc/testsuite/gcc.dg/cleanup-5.c b/gcc/testsuite/gcc.dg/cleanup-5.c new file mode 100644 index 000000000..c335c1e44 --- /dev/null +++ b/gcc/testsuite/gcc.dg/cleanup-5.c @@ -0,0 +1,53 @@ +/* HP-UX libunwind.so doesn't provide _UA_END_OF_STACK */ +/* { dg-do run } */ +/* { dg-options "-fexceptions" } */ +/* { dg-skip-if "" { "ia64-*-hpux11.*" } { "*" } { "" } } */ +/* Verify that cleanups work with exception handling. */ + +#include +#include +#include + +static _Unwind_Reason_Code +force_unwind_stop (int version, _Unwind_Action actions, + _Unwind_Exception_Class exc_class, + struct _Unwind_Exception *exc_obj, + struct _Unwind_Context *context, + void *stop_parameter) +{ + if (actions & _UA_END_OF_STACK) + abort (); + return _URC_NO_REASON; +} + +static void force_unwind () +{ + struct _Unwind_Exception *exc = malloc (sizeof (*exc)); + memset (&exc->exception_class, 0, sizeof (exc->exception_class)); + exc->exception_cleanup = 0; + +#ifndef __USING_SJLJ_EXCEPTIONS__ + _Unwind_ForcedUnwind (exc, force_unwind_stop, 0); +#else + _Unwind_SjLj_ForcedUnwind (exc, force_unwind_stop, 0); +#endif + + abort (); +} + +static void handler (void *p __attribute__((unused))) +{ + exit (0); +} + +static void doit () +{ + char dummy __attribute__((cleanup (handler))); + force_unwind (); +} + +int main() +{ + doit (); + abort (); +} -- cgit v1.2.3
