gcc compilation options in Linux

When we compile code with “–save-temps” option of gcc it generates 3 output files

• Preprocessed Code (having .i extension)
• Assembly Code (having .s extension)
• Object Code (having .o extension)

compile code without optimization option :
gcc file.c -o file –save-temps

compile code with optimization option :
gcc -O3 file.c -o file –save-temp
