Thanks Gabe. Good catch about the actual value -- I just saw a negative
number and assumed -1, whoops. Based on what Nirmit is seeing, it seems
like HINT_NOP or MOV_R_I must be the instruction causing the fault, but
yeah a backtrace will probably help confirm.
Nirmit, can you please try running
Hi Jason. The instruction definitions in gem5 can be quite complex, and
it's unlikely you'll find a lot of information about specific details like
this through Google. Probably a good place to start is to try to understand
how the ISA description files work in general, since that will give you
more
I realize this is probably a hard question to answer with Exec being
broken, but do you know what instruction is causing the problem? HINT_NOP?
Probably the first thing that someone should do (if they haven't already)
is to run this under gdb and see what the backtrace looks like, since that
would
Hi Gabe,
I was trying to dig through the RegClass code earlier to figure out why the
value is -1 for this instruction, and the only thing that I can think of is
HINT_NOP needs a RegClass value set for it, but it isn't set for some
reason (which is not 100% clear to me). You know this code much be
Hi all,
I was trying to run a gem5 simulation using the O3CPU but encountered problems
with gem5 "panic" when running with the "Exec" debug flags enabled. I have
built gem5 for the x86 ISA, and am using the stable branch.
The full log can be found in the zip linked below (crash_debug_log).
