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/pr27302-2.c | 52 ++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr27302-2.c (limited to 'gcc/testsuite/gcc.dg/torture/pr27302-2.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr27302-2.c b/gcc/testsuite/gcc.dg/torture/pr27302-2.c new file mode 100644 index 000000000..5c201b3d2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr27302-2.c @@ -0,0 +1,52 @@ +/* { dg-do run } */ +/* { dg-options "-fstrict-overflow" } */ + +extern void link_error (void); + +void test0 (int a, int b) +{ + if ((a < b) != (b > a)) + link_error (); + + if ((a - 1 < b) != (a <= b)) + link_error (); + if ((a - 2 < b) != (a - 1 <= b)) + link_error (); + if ((a + -1 < b) != (a <= b)) + link_error (); + if ((a + -2 < b) != (a + -1 <= b)) + link_error (); + + if ((a + 1 > b) != (a >= b)) + link_error (); + if ((a + 2 > b) != (a + 1 >= b)) + link_error (); + if ((a - -1 > b) != (a >= b)) + link_error (); + if ((a - -2 > b) != (a - -1 >= b)) + link_error (); + + if ((a + 1 <= b) != (a < b)) + link_error (); + if ((a + 2 <= b) != (a + 1 < b)) + link_error (); + if ((a - -1 <= b) != (a < b)) + link_error (); + if ((a - -2 <= b) != (a - -1 < b)) + link_error (); + + if ((a - 1 >= b) != (a > b)) + link_error (); + if ((a - 2 >= b) != (a - 1 > b)) + link_error (); + if ((a + -1 >= b) != (a > b)) + link_error (); + if ((a + -2 >= b) != (a + -1 > b)) + link_error (); +} + +int main() +{ + test0 (1, 2); + return 0; +} -- cgit v1.2.3
