Yes, I read this. That is why I double checked it:

$ readelf -W -s libhellomod.a
File: libhellomod.a(hello.o)
There are 19 section headers, starting at offset 0x11da8:

Section Headers:
  [Nr] Name
       Type            Addr     Off    Size   ES   Lk Inf Al
       Flags

..

  [12] .l4dde_ctors."6"
       PROGBITS        00000000 011cd4 000004 00   0   0  4
       [00000003]: WRITE, ALLOC

Symbol table '.symtab' contains 17 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name

..

     9: 00000000     4 OBJECT  LOCAL  DEFAULT   12
__l4ddekit_initcall_hello_init

..


So, looks like __l4ddekit_initcall_hello_init belongs to section 12
which is indeed .l4dde_ctors.

Best regards,
