@cindex symbol table size base
Forces the size field of the symbol table to use the given base. Any
unrecognized options will be treated as @samp{0}. @option{--sym-base=0}
represents the default and legacy behaviour. This will output sizes as decimal
for numbers less than 100000. For sizes 100000 and greater hexadecimal notation
will be used with a 0x prefix.
@option{--sym-base=8} will give the symbol sizes in octal.
@option{--sym-base=10} will always give the symbol sizes in decimal.
