assembly file : gcc -S foo.c  > foo.s
list file: gcc -Wa,-adhln -g foo.c > foo.list

map file: gcc -Wl,-Map=output.map  foo.c 
         (or) @linker level: ld -Map output.map -T linker_script.ld -N -o output.elf sourcefile1.o sourcefile2.o  

elf file : gcc foo.c -o foo.elf  (or) gcc foo.c -o foo (or) gcc foo.c generates elf a.out



List file:  is source/assembly mix file used for debugging and optimizing programs
------------
generating a mixed source and assembly listing using gcc 

$ gcc -Wa,-adhln -g source_code.c > assembly_list.s

The options:

-g: Produce debugging information
-Wa,option: Pass option as an option to the assembler
-adhln:
a: turn on listings
d: omit debugging directives; n: omit forms processing
h: include high-level source
l: include assembly
