[StackVMUnix] Illegal Instruction

Hi all,

im trying to compile the stack vm on unix with debug options because i'm getting an illegal instruction, see below

Starting program: /home/vonbecmann/bin/stack-vm/latest/results/StackVM
[Thread debugging using libthread_db enabled]

Program received signal SIGILL, Illegal instruction.
0x08092ccb in ?? ()
(gdb) bt
#0 0x08092ccb in ?? ()
#1 0x080930ee in ?? ()
#2 0x0809314d in ?? ()
#3 0x08095b77 in ?? ()
#4 0x00189ce7 in __libc_start_main () from /lib/libc.so.6
#5 0x0805cd91 in ?? ()
(gdb) x/i $pc
=> 0x8092ccb: movq %xmm7,0x8187ef8
(gdb)

But i dont know what to do next. maybe im using the wrong libraries to compile it

what should i do?? any ideas?

Thanks in advance

it could be because of -msse2 compiler option
go to #compilerFlagsDebug and remove it

Bernardo,

can you include the output from "info registers" when it crashes please?

Re: [StackVMUnix] Illegal Instruction

Hi Bernardo,

what kind of processor do you have? Does it support sse2? (it needs to for Cog & Stack VMs). Is 0x8187ef8 a valid address (e.g. what's the output of x/10w 0x8187ef8)? why are you not getting symbols in your backtrace? Are you stripping the VM by any chance? If so, please don't. Having symbols would really help in debugging this; your stack trace has only the C library entrypoint symbol. The rest is raw addresses.

No problem. If you recompile the VM without sse2 it should still work. If you look at platforms/Cross/vm/sqAtomicOps.h you'll see there are complex definitions of atomic 64-bit get64 and set64 in terms of lock cmpxchg8b. Make sure these are being used in place of the sse2 movq. Good luck!

thanks
