Hm, I had assumed this problem was fixed by importing r203311 from upstream llvm trunk, in head r263313. But apparently it is not. The upstream patch seems to fix your specific test case, but it is still in review, so I prefer to wait until it is actually committed, before I import it. -Dimitry _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "[email protected]"
