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/c-c++-common/dfp/signbit-2.c | 33 ++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/signbit-2.c (limited to 'gcc/testsuite/c-c++-common/dfp/signbit-2.c') diff --git a/gcc/testsuite/c-c++-common/dfp/signbit-2.c b/gcc/testsuite/c-c++-common/dfp/signbit-2.c new file mode 100644 index 000000000..e51bf918b --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/signbit-2.c @@ -0,0 +1,33 @@ +/* { dg-options "-O0" } */ + +/* Check that the compiler uses builtins for signbit; if not the link + will fail because library functions are in libm. */ + +#include "dfp-dbg.h" + +volatile _Decimal32 sd = 2.3df; +volatile _Decimal64 dd = -4.5dd; +volatile _Decimal128 tf = 5.3dl; +volatile float f = 1.2f; +volatile double d = -7.8; +volatile long double ld = 3.4L; + +EXTERN int signbitf (float); +EXTERN int signbit (double); +EXTERN int signbitl (long double); +EXTERN int signbitd32 (_Decimal32); +EXTERN int signbitd64 (_Decimal64); +EXTERN int signbitd128 (_Decimal128); + +int +main () +{ + if (signbitf (f) != 0) FAILURE + if (signbit (d) == 0) FAILURE + if (signbitl (ld) != 0) FAILURE + if (signbitd32 (sd) != 0) FAILURE + if (signbitd64 (dd) == 0) FAILURE + if (signbitd128 (tf) != 0) FAILURE + + FINISH +} -- cgit v1.2.3
