I sent a request to download hexagon-application-binary-interface-specification.zip a few days ago but I still don't get a copy...

The only information in the Internet about R_HEX_B15_PCREL_X is probably this patch now.. I'd say this is very inconvenient for anyone who'd like to contribute to verify the correctness. Since there is not any reference available, I can only guess.

What do the _X relocation types represent? Why are some R_PLT_PC while the others are R_PC?

  case R_HEX_B9_PCREL:
  case R_HEX_B13_PCREL:
  case R_HEX_B15_PCREL:
  case R_HEX_32_PCREL:
    return R_PC;
  case R_HEX_6_PCREL_X:
  case R_HEX_B9_PCREL_X:
  case R_HEX_B15_PCREL_X:
  case R_HEX_B22_PCREL:
  case R_HEX_PLT_B22_PCREL:
  case R_HEX_B22_PCREL_X:
  case R_HEX_B32_PCREL_X:
    return R_PLT_PC;
