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-bfp.c | 131 +++++++++++++++++++++++++++ 1 file changed, 131 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/dfp/convert-bfp.c (limited to 'gcc/testsuite/c-c++-common/dfp/convert-bfp.c') diff --git a/gcc/testsuite/c-c++-common/dfp/convert-bfp.c b/gcc/testsuite/c-c++-common/dfp/convert-bfp.c new file mode 100644 index 000000000..710538d46 --- /dev/null +++ b/gcc/testsuite/c-c++-common/dfp/convert-bfp.c @@ -0,0 +1,131 @@ +/* N1150 5.2 Conversions among decimal floating types and between + decimal floating types and generic floating types. + C99 6.3.1.5(4) Conversions, arithmetic operands, real floating types. */ + +/* Long double isn't supported yet at runtime, so disable those checks. */ + +#include "dfp-dbg.h" + +static int skip_long_double; + +volatile _Decimal32 d32; +volatile _Decimal64 d64; +volatile _Decimal128 d128; +volatile float sf; +volatile double df; +volatile long double tf; + +int +main () +{ + /* Conversions from decimal float to binary float. */ + + if (sizeof (long double) == sizeof (double)) + skip_long_double = 1; + + /* Conversions from _Decimal32. */ + d32 = 2.0df; + sf = d32; + if (sf != 2.0f) + FAILURE + + df = d32; + if (df != 2.0) + FAILURE + + if (skip_long_double == 0) + { + tf = d32; + if (tf != 2.0l) + FAILURE + } + + /* Conversions from _Decimal64. */ + d64 = -7.0dd; + sf = d64; + if (sf != -7.0f) + FAILURE + + df = d64; + if (df != -7.0) + FAILURE + + if (skip_long_double == 0) + { + tf = d64; + if (tf != -7.0l) + FAILURE + } + + /* Conversions from _Decimal128. */ + d128 = 30.0dl; + sf = d128; + if (sf != 30.0f) + FAILURE + + df = d128; + if (df != 30.0) + FAILURE + + df = d128; + if (df != 30.0l) + FAILURE + + /* Conversions from binary float to decimal float. */ + sf = 30.0f; + d32 = sf; + if (d32 != 30.0df) + FAILURE + + d64 = sf; + if (d64 != 30.0dd) + FAILURE + + df = -2.0; + d32 = df; + if (d32 != -2.0df) + FAILURE + + d64 = df; + if (d64 != -2.0dd) + FAILURE + + d128 = df; + if (d128 != -2.0dl) + FAILURE + + sf = 30.0f; + d128 = sf; + if (d128 != 30.0dl) + FAILURE + + if (skip_long_double == 0) + { + tf = -22.0l; + d32 = tf; + if (d32 != -22.0df) + FAILURE + + d64 = tf; + if (d64 != -22.0dd) + FAILURE + + d128 = tf; + if (d128 != -22.0dl) + FAILURE + } + + /* 2**(-11) = 0.00048828125. */ + d128 = 0.000488281251dl; + sf = d128; + if (sf != 0.00048828125f) + FAILURE + /* 2**(-25) = 0.298023223876953125E-7. */ + d128 = 2.98023223876953125E-8dl; + df = d128; + if (df < (2.9802322387695312e-08 - 0.00000000001) + || df > (2.9802322387695312e-08 + 0.00000000001)) + FAILURE + + FINISH +} -- cgit v1.2.3
