Hi, What is the best way to debug an llc crash using bugpoint? I am getting the following crash that I would like to reduce llc: /home/vadve/aggarwa4/llvm29/llvm-2.9/lib/MC/MCAsmStreamer.cpp:273: virtual void<unnamed>::MCAsmStreamer::EmitLabel(llvm::MCSymbol*): Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed. 0 llc 0x00000000013ae046 1 llc 0x00000000013ae5d4 2...

I tried llc -load /localhome/aggarwa4/llvm27/llvm-obj/projects/poolalloc/Debug/lib/libCodegen.so --help But this does not show my pass. It says it is an unknown command line argument.

It says it is an unknown command line argument. I'm assuming you've looked at other MachineFunctionPass'es and have registered yours in the same way that they do. I don...

...[2xi16] *.

What is the correct way to register/run a machine function pass, so that it can be dynamically loaded? Thanks, Arushi

Machine function passes are loaded into llc to be used for code generation, from the looks of it.
