Assertions are not triggered in .fast (only up to .opt). So most likely,
gem5.fast still fails the assertion, but it does not tell it to you
because assertions are disabled in .fast.

Arthur.

Hi,
If I run bbench with gem5.debug, I immediately get an error in the
code however, gem5.fast doesn't fail at that point. In fact it will
fail after so many ticks.
A bit strange... Any idea on that? I haven't modified the code yet.
gem5.debug

But gem5.fast passes that tick number. The command I use is:
build/ARM/gem5.fast configs/example/fs.py -b bbench-ics
--kernel=vmlinux.smp.mouse.arm --frame-capture
build/ARM/gem5.debugconfigs/example/fs.py -b bbench-ics
--kernel=vmlinux.smp.mouse.arm --frame-capture

Mahmood
