How to read Linker Map file

[Steven Woody]

hi,

i produced a linker map file using -M flag to 'ld'. but i found the
file is hard to understand to me.  is there a readme file or any
documents describing the file format in details?  thanks.

especially, in the map file, what is common symbols? how does it
differ with other symbols?
