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.c-torture/execute/pr39228.c | 36 +++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr39228.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr39228.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr39228.c b/gcc/testsuite/gcc.c-torture/execute/pr39228.c new file mode 100644 index 000000000..06d8efd1a --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr39228.c @@ -0,0 +1,36 @@ +extern void abort (void); + +static int __attribute__((always_inline)) testf (float b) +{ + float c = 1.01f * b; + + return __builtin_isinff (c); +} + +static int __attribute__((always_inline)) test (double b) +{ + double c = 1.01 * b; + + return __builtin_isinf (c); +} + +static int __attribute__((always_inline)) testl (long double b) +{ + long double c = 1.01L * b; + + return __builtin_isinfl (c); +} + +int main() +{ + if (testf (__FLT_MAX__) < 1) + abort (); + + if (test (__DBL_MAX__) < 1) + abort (); + + if (testl (__LDBL_MAX__) < 1) + abort (); + + return 0; +} -- cgit v1.2.3
