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/pr30360.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr30360.c (limited to 'gcc/testsuite/gcc.dg/pr30360.c') diff --git a/gcc/testsuite/gcc.dg/pr30360.c b/gcc/testsuite/gcc.dg/pr30360.c new file mode 100644 index 000000000..d4dae0d5f --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr30360.c @@ -0,0 +1,25 @@ +/* PR c/30360 */ +/* { dg-do run { target i?86-*-linux* x86_64-*-linux* ia64-*-linux* s390*-*-linux* } } */ +/* { dg-options "-O2 -std=gnu99" } */ + +#define I (__extension__ 1.0iF) +#define H(x) asm ("" : "=m" (x) : "m" (x)) +extern void abort (void); + +int +main (void) +{ + _Complex double a = 1.0 + 1.0 * I, b = 0.0, c; + H (a); + H (b); + c = a / b; + if (!__builtin_isinf (__real__ c) && !__builtin_isinf (__imag__ c)) + abort (); + a = 0.0; + H (a); + H (b); + c = a / b; + if (!__builtin_isnan (__real__ c) || !__builtin_isnan (__imag__ c)) + abort (); + return 0; +} -- cgit v1.2.3
