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.c-torture/execute/compare-2.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/compare-2.c (limited to 'gcc/testsuite/gcc.c-torture/execute/compare-2.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/compare-2.c b/gcc/testsuite/gcc.c-torture/execute/compare-2.c new file mode 100644 index 000000000..858df294e --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/compare-2.c @@ -0,0 +1,24 @@ +/* Copyright (C) 2002 Free Software Foundation. + + Ensure that the composite comparison optimization doesn't misfire + and attempt to combine a signed comparison with an unsigned one. + + Written by Roger Sayle, 3rd June 2002. */ + +extern void abort (void); + +int +foo (int x, int y) +{ + /* If miscompiled the following may become "x == y". */ + return (x<=y) && ((unsigned int)x >= (unsigned int)y); +} + +int +main () +{ + if (! foo (-1,0)) + abort (); + return 0; +} + -- cgit v1.2.3
