shark: Assertion in include/llvm/CodeGen/MachineOperand.h:251

[Robert Schuster]

Hi,
I am trying to debug the assertion issue I mentioned in the other mail.
I recompiled llvm and openjdk-6-shark with "-O0 -g" and hoped to see a
meaningful stacktrace. However this is what happened:

#0  0x406c97e8 in llvm::MachineOperand::getImm (this=warning: Unable to
fetch general register.
Cannot access memory at address 0xfffffff0
)
    at
/home/rob/oe/beagle/tmp/work/armv7a-angstrom-linux-gnueabi/llvm-2.4-r0/llvm-2.4/include/llvm/CodeGen/MachineOperand.h:251
#1  0x00000000 in ?? ()

I put a breakpoint at MachineOperand.h:251 and added a condition:
"	stop only if this.OpKind != llvm::MachineOperand::MO_Immediate"
(this is the negated assert expression)

The interesting point is, that this problem always happens when you run
'java' - whether you are pointing to a Java program or just want to see
-version.

Any ideas?

Regards
Robert
