RE: gcc ARM CPU's

["Vivek Kumar Gupta" <gkvivek at zilog dot com>]

Thanks Yann,
I have tried the trunk of 16th Nov 2008, build was successful.
Thanks again.

Just a small silly question:

Here actually I am asking "Can it be possible to give two values
together separated by comma."
Like in Tune for CPU : arm922t,cortex-m3

Reason for this, I want a single compiler for both ARM 922T and Cortex
M3 boards. 

Can it be possible by some means, like what will happen if I don't give
any values at all. Or some other way.

Right now it seems like I have to generate two compiler tool chains by
giving ARM Core Processor Types. 


Regards
Vivek

Hello Vivek!
Hello Bruno!
Hello All!

Sorry for the delay, I've been without mail server for the past two
weeks or
so, and have such a backlog...

So here's a very quick follow up, more at the end of the WE...

Try with trunk. It's in good shape at the moment, and I plan on
releasing
1.3.0 early next week. It has support for gcc-4.3.1 and 4.3.2, plus the
latest
uClibc-0.9.30 (Yeah!) and a bunch of other goodies... Feedback
appreciated before
the release! :-)

Forget about the 1.2.x series, try trunk, it's already there.

Was that a question? You can set architecture level there, yes. That is
used
as -march= parameter, but also as --with-arch= parameter when
configuring gcc.
Look at the gcc man to see possible values.
