Which Binutils should I use for performing daily regression test on trunk?

[Terry Guo]

Hi,

I plan to set up daily regression test on trunk for target
ARM-NONE-EABI and post results to gcc-testresults mailing list. Which
Binutils should I use, the Binutils trunk or the latest released
Binutils? And which way is recommended, building from a combined tree
or building separately? If there is something I should pay attention
to, please let me know. Thanks very much.

BR,
Terry
