[LLVMdev] Problems on getting UNREACHABLE executed

[Zhoujinguo]

Dear Ciao, Duncan,
Thank you for replying. I tried and the error goes away. But there comes a new error:
LLVM ERROR: Unknown object format!
How can I solve this problem?
Thank you!
BestAndy

Hi Andy,

this probably means that the bitcode contains something that is not supported
by lli, such as inline assembler.  Try passing the -use-mcjit option to lli.
If that doesn't work, feel free to open a bugreport and attach the bitcode.

Ciao, Duncan.
