nm
-M Inserts three columns in the output before each symbol name. The format
of the these columns is as follows:
rmode amode compiler_options
The rmode and amode column will display one of the following:
24 24 bit mode
31 31 bit mode
64 64 bit mode
ANY ANY mode
MIN MIN mode
--- Undetermined or not/applicable
The compiler options field will show a character for each compiler option
determined to be in effect or a dash if none are in affect:
I Symbol is compiled with IPA. Note, IPA will not be seen when
running nm against an executable because that information is no
longer available.
X Symbol is compiled with XPLINK.
–n Is equivalent to –v.
–o Displays output in octal (same as –t o).
–P Displays output in a portable POSIX-compliant format, with blanks
separating the output fields.
v If you specified –A and file is not a library, the format is:
file: name type value size.
v If you specified –A and file is a library, the format is:
file [object_file] : name type value size
where object_file is the object file in the library that contains the symbol
being described.
v If you did not specify –A, the format is:
name type value size
v If you did not specify the –t option, nm displays value and size in
hexadecimal.
v If you did not specify –A and the command line contains more than one
file, or file is a library, nm displays a line preceding the list of symbols for
each specified file or each object file in a specified library. If file is a
library, this line has the following format:
file[object_file]:
If file is not a library, the format is:
file:
–p Does not sort output.
–r Reverses sort order.
–s Includes symbol size for each symbol.
–t format
Defines the numeric value formatting base. The format is one of d, o, or x,
for decimal, octal, or hexadecimal, respectively. If this option is not used,
numbers are displayed in decimal.
–u Displays only undefined symbols.
