[LLVMdev] Compiling issues: undefined reference to `.Lline_table_start1'

[lipengcheng]

What do you mean by test case please ? Using the following commands to compile mcf program 
can reproduce such issue all the time. 

Probably it is my version's problem. Because I checked out 3.3version from SVN before published. 

Could you tell me where Manman modified ? I cannot port to new version very quickly after changing 
it a lot already. 

Thanks,
