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-41.c | 57 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtins-41.c (limited to 'gcc/testsuite/gcc.dg/builtins-41.c') diff --git a/gcc/testsuite/gcc.dg/builtins-41.c b/gcc/testsuite/gcc.dg/builtins-41.c new file mode 100644 index 000000000..5b96551fb --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtins-41.c @@ -0,0 +1,57 @@ +/* Copyright (C) 2004 Free Software Foundation. + + Check that constant folding of copysign, copysignf and copysignl math + functions doesn't break anything and produces the expected results. + + Written by Roger Sayle, 6th June 2004. */ + +/* { dg-do link } */ +/* { dg-options "-O2" } */ + +extern void link_error(void); + +extern double copysign(double, double); +extern float copysignf(float, float); +extern long double copysignl(long double, long double); + +int main() +{ + if (copysign (2.0, 1.0) != 2.0) + link_error (); + if (copysign (2.0, -1.0) != -2.0) + link_error (); + if (copysign (-2.0, 1.0) != 2.0) + link_error (); + if (copysign (-2.0, -1.0) != -2.0) + link_error (); + + if (copysign (2.0, 1.0) != 2.0) + link_error (); + if (copysign (2.0, -1.0) != -2.0) + link_error (); + if (copysign (-2.0, 1.0) != 2.0) + link_error (); + if (copysign (-2.0, -1.0) != -2.0) + link_error (); + + if (copysignf (2.0f, 1.0f) != 2.0f) + link_error (); + if (copysignf (2.0f, -1.0f) != -2.0f) + link_error (); + if (copysignf (-2.0f, 1.0f) != 2.0f) + link_error (); + if (copysignf (-2.0f, -1.0f) != -2.0f) + link_error (); + + if (copysignl (2.0l, 1.0l) != 2.0l) + link_error (); + if (copysignl (2.0l, -1.0l) != -2.0l) + link_error (); + if (copysignl (-2.0l, 1.0l) != 2.0l) + link_error (); + if (copysignl (-2.0l, -1.0l) != -2.0l) + link_error (); + + return 0; +} + -- cgit v1.2.3
