llvm dev - Nov 2013 - [LLVMdev] Quad-Core ARMv7 Build Slave Seeks Noble Purpose

Hi guys,

I have this ODROID XU (quad-core ARMv7 Cortex A15 1,6 GHz) box that I want
to make available to the LLVM project.  I can see that LLVM already has an
ARMv7 Cortex A9 system doing Clang, but how should this box be used, if at
all?  We're talking a long-term commitment within the realm of being a
buildbot slave.  It builds LLVM in about 40 minutes, excluding the test
suite.


Sincerely,
Mikael Lyngvig

Hi Mikael,

40 minutes is a good iteration time for an ARM CPU.  Are you using
some kind of caching mechanism to speed up compilation (ccache?)  If
not, it could be even faster :)

I think this buildbot will be very useful for the community.  What OS
is it running?

You can find instructions on adding a buildbot here:

http://llvm.org/docs/HowToAddABuilder.html

I am also CC'ing Galina.

Hi Dmitri,

I am not using any kind of cache (didn't even know of ccache).  I have now
installed ccache.  Perhaps ccache should be mentioned in the buildbot
 document so that every buildbot owner knows about it?

It is currently running Arch Linux ARM.  if there are good reasons to
switch to something else, I'll be happy to do that, although I am generally
very happy about Arch Linux.

What do you want me to build?  LLVM?  Clang?  Both plus test suite?


Sincerely,
Mikael
