"Branch out of range" error when compiling to mips_64 with clang-4.0

[Bowen-n]

I have successfully cross-compiled most of the gnu software following the workflow. However, for some of the software, "Branch out of range" error occurs when compiling to mips_64 with clang-4.0 (as well as clang-obfus-xxx).

For example, when compiling tar-1.30 with clang-4.0 (O0) to mips_64, it shows:

...

I have tried my best to google it but I haven't found any solution. I wonder if you have encountered similar problem before and do you have suggestions to solve it？

Hello @Bowen-n , sorry for the late reply. We did not meet such an issue during our compilation. Could you explain more about your steps and compilation environment, so that we can look into it together?
