Look at getting the linker to produce a map file ('-Map map_file' or similar).

Otherwise objdump -p and objdump -h usually give enough info.

(Any version of objdump for any architecure should work there!)

Ok with using objdump; I can get the required info.

I tried with the -Map switch to automate the file generation into build process but I get the error: 


Linking test_2010.elf...
nios2-elf-g++: dumpmap: No such file or directory
nios2-elf-g++: unrecognized option `-Map'
make: ***  Error 1

I looked at nios-elf-ld help and I found the -Map command is correct. Does this nios2-elf-g++ called from the IDE indirectly calls this linker or it uses its own set of command switches? I tried to add other linker options (i.e. --verbose , --stats) but these are working correctly.
