Sorry for confusion. I meant this change:
cvs rdiff -r1.11 -r1.12 syssrc/sys/ddb/db_elf.c
| revision 1.12
| date: 2000/07/07 21:50:26; author: jhawk; state: Exp; lines: +14 -40
| Detect ELF sections (string and symbol tables) by looking them
| up by name (in .shstrtab) instead of guessing based on section
| type (and throwing away the small one). In addition to being cleaner,
| multiple symbol tables are no longer and error condition, so
| booting netbsd.gdb no longer results in ddb being unable to use
| *any* symbols.

regular global symbols

It doesn't load shstrtab section and the behavior of current code

This shows the easiness. :-)
