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. --- libmudflap/testsuite/libmudflap.c/fail39-frag.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 libmudflap/testsuite/libmudflap.c/fail39-frag.c (limited to 'libmudflap/testsuite/libmudflap.c/fail39-frag.c') diff --git a/libmudflap/testsuite/libmudflap.c/fail39-frag.c b/libmudflap/testsuite/libmudflap.c/fail39-frag.c new file mode 100644 index 000000000..4e74ea5cd --- /dev/null +++ b/libmudflap/testsuite/libmudflap.c/fail39-frag.c @@ -0,0 +1,20 @@ +#include +#include + +int main () +{ + volatile int *k = (int *) malloc (sizeof (int)); + volatile int l; + if (k == NULL) abort (); + *k = 5; + free ((void *) k); + __mf_set_options ("-ignore-reads"); + l = *k; /* Should not trip, even though memory region just freed. */ + __mf_set_options ("-no-ignore-reads"); + l = *k; /* Should trip now. */ + return 0; +} +/* { dg-output "mudflap violation 1.*check/read.*" } */ +/* { dg-output "Nearby object 1.*" } */ +/* { dg-output "mudflap dead object.*malloc region.*" } */ +/* { dg-do run { xfail *-*-* } } */ -- cgit v1.2.3
