Perhaps you noticed that LLVM gained a new optimizing register allocator yesterday (r130568). Linear scan is going away, and RAGreedy is the new default for optimizing builds. Hopefully, you noticed because your binaries were suddenly 2% smaller and 10% faster*. Some noticed because LLVM started crashing or miscompiling their code. Greedy replaces a fairly big chunk of the code generator, so

For some reason that I have not yet been able to figure out, these tests run significantly more slowly when I run them during the daytime, which I did for that run.

How big was that log file? If we are running close to the limit, I can just buy a new disk for zion. Other suggestions welcome. --Vikram On Nov 25, 2006, at 12:38 AM, John T.

A big compile time regression. Any ideas? Ciao, Duncan.

Nothing that I'm aware of has changed with EH.

Hi Bill, > Nothing that I'm aware of has changed with EH. Is it possible to bisect the problem? I don't see any relevant LLVM changes, so I guess clang C++ compilation slowed down due to some clang changes. I'm not going to investigate this.

Did something change with exception handling recently? A bunch of lit bots are showing slower compile times for many tests. Ciao, Duncan.

Hello, I was interested in how much Type-Based Alias Analysis helps to optimize code. For that purpose, I've compared three sets of benchmarks: compiled without TBAA, compiled with a default TBAA metadata format, and compiled with new TBAA metadata format. As a set of benchmarks, I've used the LLVM test suite (http://llvm.org/docs/TestingGuide.html#test-suite-overview) which has a lot of

I think there is a very similar situation with the PowerPC/Mac OS X nightly tests. Over each of the past few nights, something has been filling up the process table, causing me to be unable to log in. The nightly tester wrote out regression test and feature test logs featuring hundreds of "Resource temporarily unavailable" errors from fork(), so I assume it's the qmtest

Vladimir, Did the checkout fail? Its trying to do a chdir("llvm") in the build directory (second argument to the script) but that directory doesn't exist or isn't executable. Can you verify that you have an $HOME/pkg/build/llvm/night/build/llvm dir? Reid. On Thu, 2004-06-24 at 10:42, Vladimir Merzliakov wrote: > > Are you using the NightlyTest.pl file? To run the
