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/ieee/acc1.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/ieee/acc1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/ieee/acc1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/ieee/acc1.c b/gcc/testsuite/gcc.c-torture/execute/ieee/acc1.c new file mode 100644 index 000000000..e0d969b9d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/ieee/acc1.c @@ -0,0 +1,18 @@ +/* Tail call optimizations would reverse the order of additions in func(). */ + +double func (const double *array) +{ + double d = *array; + if (d == 0.0) + return d; + else + return d + func (array + 1); +} + +int main () +{ + double values[] = { 0.1e-100, 1.0, -1.0, 0.0 }; + if (func (values) != 0.1e-100) + abort (); + exit (0); +} -- cgit v1.2.3
