GCC (LINUX)

COMPILATION SYNTAX

x32

#OPTIMIZATION TURNED ON
root@dev:~$ gcc -g -m32 -O1 sourceFile.c outputFile.out
 * -g is used for debug symbols
    - displays friendly function names and may correlate the source code with assembly code when disassembling
 * -m32 compiles the source into a x32 bit program
    - can be used as a training aid when dealing with smaller registers
 * -O1 turns on compiler optimization
    - capital O not zero
 * -O0 turns off compiler optimization
 
 
 #OPTIMIZATION TURNED OFF
 root@dev:~$ gcc -g -m32 -O0 sourceFile.c outputFile.out
 
 
 #
 root@dev:~$ sudo apt install gcc-multilib -y
  * this install the x32 libraries required to compile x32 bit programs

x64

#OPTIMIZATION TURNED ON
root@dev:~$ gcc -g -m64 -O1 sourceFile.c -o outputFile.out
 * -g is used for debug symbols
    - displays friendly function names and may correlate the source code with assembly code when disassembling
 * -m32 compiles the source into a x32 bit program
    - can be used as a training aid when dealing with smaller registers
 * -O1 turns on compiler optimization
     - use -O2 or -O3 for more aggressive optimization
        - capital O not zero
 * -O0 turns off compiler optimization
 
 
 #OPTIMIZATION TURNED OFF
