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/convert-dfp-fold.c | 47 +++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/convert-dfp-fold.c (limited to 'gcc/testsuite/c-c++-common/dfp/convert-dfp-fold.c') diff --git a/gcc/testsuite/c-c++-common/dfp/convert-dfp-fold.c b/gcc/testsuite/c-c++-common/dfp/convert-dfp-fold.c new file mode 100644 index 000000000..67c9d71c2 --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/convert-dfp-fold.c @@ -0,0 +1,47 @@ +/* { dg-options "-O2" } */ + +/* N1150 5.2 Conversions among decimal floating types and between + decimal floating types and generic floating types. + C99 6.3.1.5(3) New. */ + +#include "dfp-dbg.h" + +extern void link_error (); + +int +main () +{ + _Decimal32 d32; + _Decimal64 d64; + _Decimal128 d128; + + /* Conversions to larger types. */ + d32 = 123.4df; + d64 = d32; + if (d64 != 123.4dd) + link_error (); + d128 = d32; + if (d128 != 123.4dl) + link_error (); + d64 = 345.678dd; + d128 = d64; + if (d128 != 345.678dl) + link_error (); + + /* Conversions to smaller types for which the value fits. */ + d64 = 3456.789dd; + d32 = d64; + if (d32 != 3456.789df) + link_error (); + d128 = 123.4567dl; + d32 = d128; + if (d32 != 123.4567dl) + link_error (); + + d128 = 1234567890.123456dl; + d64 = d128; + if (d64 != 1234567890.123456dd) + link_error (); + + return 0; +} -- cgit v1.2.3
