Hi,
I am using marssx86 to run a fedora 14 os. After I boot the machine and
start the simulation from the QEMU monitor, the VM exits with some error
message.

ptlsim/build/core/ooo-core/ooo-pipe.cpp:2131: int
ooo::ReorderBufferEntry::commit(): Assertion `uop.eom' failed.
I did a quick search online and find this maybe caused by an unsupported
opcode, but I am not sure about the cause.
Could anyone tell me how to debug this error message or find the
unsupported opcode? Thanks.

PS.
More information Š.
The code snippet is from ooo-pipe.cpp is
if unlikely (isclass(uop.opcode, OPCLASS_BRANCH)) {
assert(uop.eom);
If the uop is a branch class opcode and it should be set an eom. This
looks an exception for this case.
Any comment?
