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.dg/builtins-44.c | 58 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtins-44.c (limited to 'gcc/testsuite/gcc.dg/builtins-44.c') diff --git a/gcc/testsuite/gcc.dg/builtins-44.c b/gcc/testsuite/gcc.dg/builtins-44.c new file mode 100644 index 000000000..1f1eaf0f6 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtins-44.c @@ -0,0 +1,58 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fno-trapping-math -fno-finite-math-only -fdump-tree-optimized" } */ + +extern void f(int); +extern void link_error (); + +extern float x; +extern double y; +extern long double z; + +int +main () +{ + double pinf = __builtin_inf (); +#ifndef __SPU__ + /* The SPU single-precision floating point format does not support Inf. */ + float pinff = __builtin_inff (); +#endif + long double pinfl = __builtin_infl (); + + if (__builtin_isinf (pinf) != 1) + link_error (); +#ifndef __SPU__ + if (__builtin_isinf (pinff) != 1) + link_error (); + if (__builtin_isinff (pinff) != 1) + link_error (); +#endif + if (__builtin_isinf (pinfl) != 1) + link_error (); + if (__builtin_isinfl (pinfl) != 1) + link_error (); + + if (__builtin_isinf_sign (-pinf) != -1) + link_error (); +#ifndef __SPU__ + if (__builtin_isinf_sign (-pinff) != -1) + link_error (); +#endif + if (__builtin_isinf_sign (-pinfl) != -1) + link_error (); + + if (__builtin_isinf (4.0)) + link_error (); + if (__builtin_isinf (4.0)) + link_error (); + if (__builtin_isinff (4.0)) + link_error (); + if (__builtin_isinf (4.0)) + link_error (); + if (__builtin_isinfl (4.0)) + link_error (); +} + + +/* Check that all instances of link_error were subject to DCE. */ +/* { dg-final { scan-tree-dump-times "link_error" 0 "optimized" } } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
