Hi,
I recently downloaded and installed the libcpu package (from http://libcpu.org) that uses llvm as the backend on my linux machine. I have a piece of Motorola 88100 code (essentially the output of the 176.gcc benchmark from SPEC CPU 2000) that I am trying to run using this emulator, but I am running into errors when trying to run it.
Has anyone been able to successfully use the m88k emulator from libcpu? Any suggestions/tips on how to get it working would be greatly appreciated.
Thanks,
Pradeep.
What kinds of errors are you getting?
To give a little more background, the file that I am trying to run is an m88k assembly file. So, I run it as
./build/libcpu test_m88k assembly file
It prints a huge llvm assembly file first and then aborts giving the following error.
test_m88k: ScheduleDAGRRList.cpp:244: void<unnamed>::ScheduleDAGRRList::ScheduleNodeBottomUp(llvm::SUnit*, unsigned int): Assertion `CurCycle >= SU->getHeight() && "Node scheduled below its height!"' failed.
Stack dump:
0. Running pass 'X86 DAG->DAG Instruction Selection' on function '@jitmain'
Aborted
Does this give you any ideas?
Pradeep.
