- Subject: Proposed testcase for PR 7344
This is intended to go in the gcc.dg directory. Comments welcome, since
I'm pretty new to testsuite work. I titled it switch-2.c since I don't
like the by-date naming convention, and it's a pretty generic test.
* gcc.dg/switch-2.c: New test.

makes a 10,000 case switch. See e.g. PR 7344. */
