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-1.c | 40 ++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/signbit-1.c (limited to 'gcc/testsuite/c-c++-common/dfp/signbit-1.c') diff --git a/gcc/testsuite/c-c++-common/dfp/signbit-1.c b/gcc/testsuite/c-c++-common/dfp/signbit-1.c new file mode 100644 index 000000000..d83d2a48e --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/signbit-1.c @@ -0,0 +1,40 @@ +/* { dg-options "-O0" } */ + +/* Decimal float versions of __builtin_signbit. */ + +#include "dfp-dbg.h" + +#define CHECK32(D,I) \ + if ((__builtin_signbitd32 (D) != 0) != I) FAILURE + +#define CHECK64(D,I) \ + if ((__builtin_signbitd64 (D) != 0) != I) FAILURE + +#define CHECK128(D,I) \ + if ((__builtin_signbitd128 (D) != 0) != I) FAILURE + +/* Prevent the compiler from folding the calls at compile time. */ +volatile _Decimal32 sd; +volatile _Decimal64 dd; +volatile _Decimal128 td; + +int +main () +{ + sd = 1.9df; CHECK32 (sd, 0) + sd = -5.3df; CHECK32 (sd, 1) + sd = 0.0df; CHECK32 (sd, 0) + sd = -0.0df; CHECK32 (sd, 1) + + dd = 1.9dd; CHECK64 (dd, 0) + dd = -5.3dd; CHECK64 (dd, 1) + dd = 0.0dd; CHECK64 (dd, 0) + dd = -0.0dd; CHECK64 (dd, 1) + + td = 1.9dl; CHECK128 (td, 0) + td = -5.3dl; CHECK128 (td, 1) + td = 0.0dl; CHECK128 (td, 0) + td = -0.0dl; CHECK128 (td, 1) + + FINISH +} -- cgit v1.2.3
