   /* A PC Relative 11-bit relocation, shifted by 3.
-     This reloc is complicated because relocations are relative to the upper
-     instruction, and I don't think BFD handles 64 bit instructions easily.
-     We could set the address of the reloc as the address of the lower
-     instruction, but then we'd have to do what is done for R_M32R_10_PCREL

+     Fortunately, the lower instruction has the lower address in the 64 bit
+     pair.  Thus we can treat the address of the instruction as a whole
+     as the address of the lower instruction (the one with the branch),
+     and pretend the instruction size is 32 bits.
+     Otherwise, we'd have to either perform the relocation on all 64 bits
+     (since the pc relative address is the start of the pair), or set the
+     address of the reloc as the address of the lower instruction and do what
+     is done for R_M32R_10_PCREL which is to mask off the lower 3 bits of the
