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
