Please add a new testcase instead of modifying an old one. I think
there are only a couple of reasons why you should ever be editing a
Please note that this is _not_ a change, just an addition. It won't
interfer with current testcase functionality in any way. It was a
common practice in the past that missing folds were just added to
various builtin-*.c file, because these subtests were clearly
separated, and were pass/fail type. An example of this practice is:

* gcc.dg/builtins-20.c: Add checks for sin(x)/tan(x) and
tan(x)/sin(x) transformations.
That said, it is no problem for me to add new file. I'm just worried
of dozens of little files with trivial folding checks.
