[llvm-dev] Buildbot for minimum supported GCC version? (seeing local build failures)

Hello James,

I believe r351756 should fix the build error in OptionalTest that you
are seeing.

As for the buildbots, I agree we should have a buildbot building with
the minimum supported compiler version. If noone cares about that
configuration enough to put one up, maybe we should consider dropping
support for that version?

I'm currently seeing a build failure locally using v4.8.4, due to a compiler bug fixed in 4.9 (see GCC bug id 57824), coming from OptionalTest.cpp, relating to raw string literals in macros not being able to encompass multiple lines. The change in question (r351548) was introduced 3 days ago, and as far as I can see hasn't flagged up a build bot failure.

I haven't yet tracked down the revision in question for this (it's possible it's r351701 (and not fixed by r351728) but also possible that something on my machine has got messed up), but removing the contents of xray-converter.cpp means I can at least build successfully.
