in order to load the symbol table. Instead of using the sections
called ".symtab" and ".strtab", use the first SYMTAB section (the
ELF spec says there should currently only be one) and the STRTAB
section that's linked to it. I believe this is more robust, and it
certainly makes life easier for the bootloader.
"preserving" implies that the data may be copied and might otherwise
be freed, and that other data in the symbol table or sections of
the kernel might be freed, however there is no mechanism for these
things to take place, so "using" is clearer.
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.
the same name); it searches the symbol table(s) for all symbols matching
a given substring, and prints.
Extremely useful for when you forget that critical symbol name.
Also, with /F support (cf. "ls -F") to print a char indicating the
symbol type.
