-C

-demangle[=style]

Decode (demangle) low-level symbol names into user-level names. Besides removing any initial

underscore prepended by the system, this makes C++ function names readable. Different compil-

ers have different mangling styles. The optional demangling style argument can be used to choose

an appropriate demangling style for your compiler. Chapter 10 c++ﬁlt, for more information on

demangling.

-no-demangle

Do not demangle low-level symbol names. This is the default.

-D

-dynamic

Display the dynamic symbols rather than the normal symbols. This is only meaningful for dy-

namic objects, such as certain types of shared libraries.

-f format

-format=format

Use the output format format, which can be bsd, sysv, or posix. The default is bsd. Only the

ﬁrst character of format is signiﬁcant; it can be either upper or lower case.

-g

-extern-only

Display only external symbols.

-l

-line-numbers

For each symbol, use debugging information to try to ﬁnd a ﬁlename and line number. For a

deﬁned symbol, look for the line number of the address of the symbol. For an undeﬁned sym-

bol, look for the line number of a relocation entry which refers to the symbol. If line number

information can be found, print it after the other symbol information.

-n

-v

-numeric-sort

Sort symbols numerically by their addresses, rather than alphabetically by their names.

-p

-no-sort

Do not bother to sort the symbols in any order; print them in the order encountered.

-P

-portability

Use the POSIX.2 standard output format instead of the default format. Equivalent to -f posix.

-S

-print-size

Print size, not the value, of deﬁned symbols for the bsd output format.
