Hi Ahmad,
I suspect gcc 4.6 has issues with LTO. I suspect opt works fine, and if you
want fast, then “--no-lto” should work.
I have a 12.04.03 machine with stock gcc 4.6 and it does have some link-time
warnings for X86, but no errors. Odd…

Hi Andreas,
My environment is:
Ubuntu precise (12.04.3 LTS)
gcc 4.6
To be precise, it is a linking error, not the compilation one.
Regards,
On 10 October 2014 10:42, Andreas Hansson

Hi Ahmad,
That is odd. Could you elaborate on what environment you are building in?
I’ve tested this on Ubuntu 12.04, RHE5/6 and OSX with clang 3.4/3.5, gcc 4.6
and 4.9 without any problems.

Hi all,
With today’s push to the gem5 trunk (not stable) I am very pleased to announce
that DRAMPower is now integrated as the power model backing up the built-in
gem5 DRAM controller. Datasheet IDD values are provided for the existing
LPDDR2/LPDDR3 and DDR3/DDR4 configurations, but obviously there is nothing
stopping people from exploring further. The energy and power results are part
of the normal gem5 stats.
I would like to especially thank the DRAMPower developers for accommodating the
integration, and I am sure there will be a continued mutual benefit from having
the two tools work together. With Nilay’s recent Ruby patches this integration
should also benefit all Ruby users very shortly.
We hope all gem5 users enjoy the new functionality.
Kind regards,
Andreas
