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.target/sh/sh4a-fprun.c | 37 ++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.target/sh/sh4a-fprun.c (limited to 'gcc/testsuite/gcc.target/sh/sh4a-fprun.c') diff --git a/gcc/testsuite/gcc.target/sh/sh4a-fprun.c b/gcc/testsuite/gcc.target/sh/sh4a-fprun.c new file mode 100644 index 000000000..40c2b05aa --- /dev/null +++ b/gcc/testsuite/gcc.target/sh/sh4a-fprun.c @@ -0,0 +1,37 @@ +/* Verify that fsca and fssra yield reasonable results. */ +/* This test calls the sinf and cosf library functions for targets other + than sh4a, but the VxWorks kernel doesn't have those functions. */ +/* { dg-do run { target { "sh*-*-*" && { ! vxworks_kernel } } } } */ +/* { dg-options "-O -ffast-math" } */ + +#include +#include + +float sqrt_arg = 4.0f, sqrt_res = 2.0f; +float dg2rad_f; +double dg2rad_d; + +void check_f (float res, float expected) { + if (res >= expected - 0.001f && res <= expected + 0.001f) + return; + + abort (); +} + +void check_d (double res, double expected) { + if (res >= expected - 0.001 && res <= expected + 0.001) + return; + + abort (); +} + +int main() { + check_f (sqrtf(sqrt_arg), sqrt_res); + dg2rad_f = dg2rad_d = atan(1) / 45; + check_f (sinf(90*dg2rad_f), 1); + check_f (cosf(90*dg2rad_f), 0); + check_d (sin(-90*dg2rad_d), -1); + check_d (cos(180*dg2rad_d), -1); + check_d (sin(-45*dg2rad_d) * cosf(135*dg2rad_f), 0.5); + exit (0); +} -- cgit v1.2.3
