Hi: This was from my pile of workload dated back to the LLVM6.0 Release. I had a transform pass which generates perfectly valid IR containing a bunch of indirectbr instructions. Seems like when targeting AArch64 backend , the compiler would crash with a message "Fatal Error: Error in backend: Unsupported relocation of variable '' "

I'd like to know if this is a known bug and has been fixed in the 7.0 release? Since I haven't got time to reduce the affected IR and submit a proper bug report yet.

Hello Zhang,

I don't think we can give you much of an answer without more details. A brief grep for similar strings gives one result of "unsupported relocation of variable" in Target/X86/MCTargetDesc/X86MachObjectWriter.cpp

Given that you were targeting AArch64 something strange must have happened or a similar string was removed from the AArch64 backend. Either way I don't think we can say that the problem you were seeing has been fixed.

Peter
