--- Comment #49 from Jeffrey A. Law <law at redhat dot com> --- Richi, see c#45. Basically the regression is "gone" for the testcase as-is... But it's pretty easy to twiddle it slightly and show the regression. It's also important to note this is e500 code, so you need to configure your toolchain appropriately.
