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/builtins-31.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtins-31.c (limited to 'gcc/testsuite/gcc.dg/builtins-31.c') diff --git a/gcc/testsuite/gcc.dg/builtins-31.c b/gcc/testsuite/gcc.dg/builtins-31.c new file mode 100644 index 000000000..6e1bda0b7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtins-31.c @@ -0,0 +1,36 @@ +/* Copyright (C) 2004 Free Software Foundation. + + Check that constant folding of signbit, signbitf and signbitl math + functions doesn't break anything and produces the expected results. + + Written by Roger Sayle, 28th January 2004. */ + +/* { dg-do link } */ +/* { dg-options "-O2" } */ + +extern void link_error(void); + +extern int signbit(double); +extern int signbitf(float); +extern int signbitl(long double); + +int main() +{ + if (signbit (1.0) != 0) + link_error (); + if (signbit (-2.0) == 0) + link_error (); + + if (signbitf (1.0f) != 0) + link_error (); + if (signbitf (-2.0f) == 0) + link_error (); + + if (signbitl (1.0l) != 0) + link_error (); + if (signbitl (-2.0f) == 0) + link_error (); + + return 0; +} + -- cgit v1.2.3
