Unfortunately they use utterly different letter abbreviations. It is so different
-t --syms Print the symbol table entries of the file. This is similar to the information provided by the nm program, although the display format is different. The format of the output depends upon the format of the file being dumped, but there are two main types. One looks like this:
[ 4](sec 3)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .bss [ 6](sec 1)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000 fred
where the number inside the square brackets is the number of the entry in the symbol table, the sec number is the section number, the fl value are the symbol's flag bits, the ty number is the sym- bol's type, the scl number is the symbol's storage class and the nx value is the number of auxiliary entries associated with the sym- bol. The last two fields are the symbol's value and its name.
The other common output format, usually seen with ELF based files, looks like this:
00000000 l d .bss 00000000 .bss 00000000 g .text 00000000 fred
Here the first number is the symbol's value (sometimes referred to as its address). The next field is actually a set of characters and spaces indicating the flag bits that are set on the symbol. These characters are described below. The next field is another number associated with the symbol, which for common symbols is the alignment and for other symbol is the size. Finally the symbol's name is displayed.
"l" "g" "!" The symbol is local (l), global (g), neither (a space) or both (!). A symbol can be neither local or global for a variety of reasons, eg because it is used for debugging, but it is proba- bly an indication of a bug if it is ever both local and global. "w" The symbol is weak (w) or strong (a space).
"C" The symbol denotes a constructor (C) or an ordinary symbol (a space).
"W" The symbol is a warning (W) or a normal symbol (a space). A warning symbol's name is a message to be displayed if the sym- bol following the warning symbol is ever referenced.
"I" The symbol is an indirect reference to another symbol (I) or a normal symbol (a space).
"d" "D" The symbol is a debugging symbol (d) or a dynamic symbol (D) or a normal symbol (a space).
"F" "f" "O" The symbol is the name of a function (f) or a file (F) or an object (O) or just a normal symbol (a space).
