Hello,

yes, there are relocations on the auipc instruction:

   8:   00000097                auipc   ra,0x0
                        8: R_RISCV_CALL label
                        8: R_RISCV_RELAX        *ABS*


But according to the Instruction Set Manual Version 2.2 the auipc instruction
does the following: Expand the 20bit U-immediate with zeros, add it to PC and
store the result in register (in this case ra). In this case this is 8 in ra.

So I do not exactly know what these relocations mean, but it still seems to be
an issue here.

Regards
Joachim
