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/torture/pr28045.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr28045.c (limited to 'gcc/testsuite/gcc.dg/torture/pr28045.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr28045.c b/gcc/testsuite/gcc.dg/torture/pr28045.c new file mode 100644 index 000000000..f2d16646c --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr28045.c @@ -0,0 +1,22 @@ +/* { dg-do run } */ + +extern void abort(void); +struct a +{ + unsigned int bits : 1; + signed long val : ((sizeof(long) * 8) - 1); +}; +int Fnegate (struct a b) +{ + if ((-((long)b.val)) <= ((long) ((1UL << ((sizeof(long) * 8) - 2)) -1UL)) + && (-((long)b.val)) >= (-(((long) ((1UL << ((sizeof(long) * 8) - 2)) -1UL))) - 1)) + return 0 ; + abort (); +} +int main () +{ + struct a b = {1, 1}; + Fnegate (b); + return 0; +} + -- cgit v1.2.3
