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/20041106-1.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/20041106-1.c (limited to 'gcc/testsuite/gcc.dg/20041106-1.c') diff --git a/gcc/testsuite/gcc.dg/20041106-1.c b/gcc/testsuite/gcc.dg/20041106-1.c new file mode 100644 index 000000000..f83e835ed --- /dev/null +++ b/gcc/testsuite/gcc.dg/20041106-1.c @@ -0,0 +1,31 @@ +/* { dg-do run { target *-*-linux* *-*-solaris* } } */ +/* { dg-options -O2 } */ + +#include +#include +#include +#include + +struct S { long x __attribute__((packed)); }; /* { dg-warning "attribute ignored" "" { target default_packed } } */ +volatile long sink; + +void foo (struct S *s) +{ + sink = s->x; +} + +int main () +{ + size_t ps = getpagesize (); + char *ptr, *page; + struct S *s; + + ptr = malloc (3*ps); + page = (char *)(((size_t)ptr + (ps - 1)) & -ps); + munmap (page + ps, ps); + + s = (struct S *)(page + ps - sizeof(struct S)); + foo(s); + + return 0; +} -- cgit v1.2.3
