Sorry, I did not find it in "AS". I did saw .text .data .bss and some
other new segment created by "AS" through function "subseg_new", but I
could not find out where and how ".rela.debug_info" is generated. For
this case, "as" dwarf2dbg.c(binutils-2.29.1): 1932
if(emit_other_sections) does not run (emit_other_section==0).
My understand, all .debug_XXX is generated by GCC, "AS" just copy them
to obj, not a bit change. But I also could not find ".rela.X" in GCC.
Did I miss something? I need a breakpoint to see "Oh it really
created it there~"
