Hi, Using trunk llvm ; on powerpc (powerpc64/power7); trying to do a "gmake check", the sed bits in test/Makefile appear to be getting tripped up when trying to generate lit.site.cfg. I've started to hack at it, made a little bit of progress, but wonder if I'm just digging myself a hole. Highlights of what I've poked at are below.. Comments or thoughts? Thanks,

Hi Since the buildbot host was updated to Fedora F20 levels, the clang buildbot has been failing with the following: $ /home/clangbuild/clang-ppc64-1/lnt.venv/bin/lnt runtest --verbose --submit http://llvm.org/perf/submitRun --commit=1 nt --sandbox nt --no-timestamp --cc /home/clangbuild/clang-ppc64-1/llvm.install.1/bin/clang --cxx /home/clangbuild/clang-ppc64-1/llvm.install.1/bin/clang++

My colleague Will Schmidt recently discovered (http://llvm.org/bugs/show_bug.cgi?id=21048) that the LLVM optimizers are converting sqrt(n), where n is negative, into 0.0. Now, as Sanjay pointed out, the value of sqrt(n) for negative n other than -0.0 is undefined according to the C99 standard, so this is allowable behavior. But I think that it's not necessarily good behavior, nonetheless.

I'm adding the dev list to this discussion, as it's a bit meta, and not specific to these patches.
