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/pr29798.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr29798.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr29798.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr29798.c b/gcc/testsuite/gcc.c-torture/execute/pr29798.c new file mode 100644 index 000000000..f7b90da02 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr29798.c @@ -0,0 +1,26 @@ +extern void abort (); + +int +main () +{ + int i; + double oldrho; + double beta = 0.0; + double work = 1.0; + for (i = 1; i <= 2; i++) + { + double rho = work * work; + if (i != 1) + beta = rho / oldrho; + if (beta == 1.0) + abort (); + + /* All targets even remotely likely to ever get supported + use at least an even base, so there will never be any + floating-point rounding.
