We were wondering what kind of support we could give to make sure ARM
code is correct and don't regress, specially before releases (I know
it's a bit late for 2.9).

LLVM 2.9 was forked off the trunk at Revision 127228 so the above
regressions are not in LLVM 2.9.<br>
unfortunally a fold-pcmpeqd-0.ll regression got into the 2.9 fork.<br>

Hope this will help fix the regressions<br>

We have thought about some routes:
- Install some build slaves on our side, so you can test them (linux,
bare-metal), if it's possible to cross-compile on build slaves.

<pre wrap="">
there are several idle ARM buildslaves. There are the following slaves:
gcc35: # 1TB 0.8 GHz Freescale i.MX515 (ARM Cortex-A8) / 512 MB RAM
/ Efika MX Client Dev Board
gcc50: # 250G 0.6 GHz ARM XScale-80219 / 512 MB RAM / Thecus N2100 NAS
gcc55: # 250G 1.2 GHz ARM Feroceon 88FR131 (kirkwood) / 512 MB RAM /
Marvell SheevaPlug
gcc56: # 320G 1.2 GHz ARM Feroceon 88FR131 (kirkwood) / 512 MB RAM /
Marvell SheevaPlug
gcc57: # 320G 1.2 GHz ARM Feroceon 88FR131 (kirkwood) / 512 MB RAM /

I can give you access to these machines if you like (send me your public ssh
key).
Ciao, Duncan.
