The IRET instruction is implemented in
arch/x86/isa/insts/general_purpose/control_transfer/interrupts_and_exceptions.py.
It's fairly involved since IRET is an inherently complicated instruction,

at the time it was written.
I think the confusion comes from the fact that accesses in atomic mode
return right away, where in timing mode they are split into a call which
starts the transaction, and a callback with the results. In atomic mode,

Hi Lukas. It's not really clear from your description what the problem is,
but I would expect the "size()" method to be very simple, and so the "root"
pointer is probably null or corrupt. You should probably look into where
that value is coming from and what might have happened to it.

It looks like you might be running out of memory, which building too many
things at once could contribute to. The final link is going to use a lot of
memory no matter what, most likely.

This question has been asked (and answered) on this list already. Please
don't ask the same question multiple times.

Hi, sorry for taking a while to get back to you. The cxx-config code is not
quite correct, although it basically works in most cases. It fails to build
with the systemc integration, but you don't want to use gem5's built in
systemc kernel anyway, if you're going to run it inside another external
It's normal for valgrind to slow things down a lot. One thing you can do to
at least improve the quality of the errors you get is to use the
suppressions file in util/valgrind-suppressions. The python interpreter
does a lot of things which upset valgrind, and this tells valgrind mostly
to ignore
The standard library you're linking against is newer, and is using a system
call that gem5 doesn't implement. You'll either need to use an older
standard library, or implement that system call. If you're trying to run
gem5's tests, then I know at least one of the x86 ones uses dynamic linking
and

It sounds to me like you've somehow installed the gem5 git hooks for
everything on your machine through either the user global or a machine
global git config. What you want to do is install the hooks (scripts or
links in .git/hooks) in the gem5 repository itself. SCons will prompt you
to do this
