How to interpret *.map File

steffen_ger

Hello,
I want to know the size of the compiled functions.
In the map file I find this sorted by abs value :

GLOBAL SYMBOLS: SORTED BY Symbol Address

abs. value/
byte addr word addr name
--------- --------- ----

000144d9                _fir_lib_block
000144db                _fir_c_fix
000145af                _fir_c_fix_opt
00014686                _fir_c_float

Is the byte size of _fir_c_fix = 0x145af - 0x144db = dec212 ?

Yes that is one way to derive the information from the map file. There is also a package of code generation tools processing scripts which contain several useful scripts for post-processing executables and libraries. Please take a look at http://processors.wiki.ti.com/index.php/Code_Generation_Tools_XML_Processing_Scripts. One of the scripts in this package is func_info which basically gives the information you are looking for. It produces a listing of all functions, the C/asm file it came from, address ranges and sizes in CSV format.
