Is there a timeline for when dragonegg might be merged into gcc (4.6 perhaps)? I ask because FSF gcc has allowed code in as technology previews before. For instance, graphite really wasn't that usable in gcc 4.4 and produced wrong code in the Polyhedron 2005 benchmarks until gcc 4.5. So as long as it can bootstrap gcc 4.6 and works in general, dragonegg should qualify for inclusion as an e...

Howdy all... Reading with interest the thread(s) about REvolution, package licensing and the requirements of the GPL. First of all, let me introduce myself?. ?I joined REvolution Computing in February, after working for nearly 4 years for Intel as an open source strategist and before that for 6 years at Sun, where I established the first corporate open source programs office. ?I'm a Member of

Nick, Can you take a quick look at the asan_eh_bug.tar.bz testcase I uploaded into the newly opened radr://12777299, "potential pthread/eh bug exposed by libsanitizer". The FSF gcc developers have ported llvm.org's asan code into FSF gcc (and are keeping it synced to the upstream llvm.org code). I have been helping with the darwin build and testing -fsanitize=address against the complete FSF gcc testsuite. This seems to have exposed a potential bug in pthread or eh on...

Now that dragoneegg is robust in its default usage and the dragonegg svn is moderately stable with -fplugin-arg-dragonegg-enable-gcc-optzns, it is possible to gauge the impact of that feature. Comparing clang 2.9, FSF gcc 4.5.3svn, FSF gcc 4.6.0 and dragonegg svn with FSF gcc 4.5.3svn using the himenoBMTxpa benchmark, the enhancement to code performance from -fplugin-arg-dragonegg-enable-gcc-optzns is clear on x86_64-apple-darwin10 for -fomit-frame-pointer -O3 -ffast-math -funroll-loops... compiler...

...an "Sarge" it is; for Mac OS X you need to ifconfig lo0 .... alias. But once you have, connect to 127.0.0.2:running- service to verify that the host believes that 127.0.0.2 is a valid IPV4 address for loopback 2) Start an ssh port forwarded tunnel. For me, that's: ssh -L 2426:mail.fsf.net:25 -N adam at mail.fsf.net 3) connect to the forwarded port at 127.0.0.1. For me, telnet 127.0.0.1 2426 Trying 127.0.0.1... Connected to 127.0.0.1.

Duncan, With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html, the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12. The result are similar to what were seen with FSF gcc 4.6.2svn and llvm/dragonegg 3.0 (which was the last release that passed pb05) http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/044091.html. Jack ps Has an exhaustive effort been made yet to insure that llvm/dragonegg isn't still unnecessarily scalarizing the vector code gen...
