--- Comment #20 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
here:

an extra pointer in powerpc_opcode:

https://git.libre-soc.org/?p=binutils-gdb.git;a=blob;f=include/opcode/ppc.h;h=8c356b1ff4c0e82d7dd8b367cb27559707fd14dd;hb=84629a61ee0f459a78e245e5aa41bec73f30c4d1#l64

  35 struct powerpc_opcode
  36 {
  38   const char *name;
  42   uint64_t opcode;
  48   uint64_t mask;
  53   ppc_cpu_t flags;
  58   ppc_cpu_t deprecated;
  63   unsigned char operands[8];
       svp64_opcode_table* svp64;
  64 };

where here, the *AUTO-GENERATED* svp64_opcode_table would be "merged"
by this function:

into this massive table of epic proportions:
