How do you get assembler output from C/C++ source in gcc? -


How does it?

If I want to analyze how something is compiling, how will I get the emission code emitted?

Use the -s option for GCC (or G ++ ). 

  gcc -s helloworld.c   
 This will run the preprocessor (cpp) on helloworld.c, stop the initial compilation and then before executing the assembler .  
 By default this will output a file to  helloworld.s . The output file can still be set using the  -o  option.  
  gcc-s-o my_asm_output.s helloworld.c   
 This only works if you have the original source optional If you only have the result If the object is the file, then  - disassemble  option (or  -d  form briefly) using  objdump .  
  obzump-s - dysassable hellcarold & gt; This option works best if the debugging option is enabled for the Helloworld.dump   
 object file (at  -g  compile time) and the file is not snatched .  
 Running  file helloworld  gives you some prompts as the level of detail that you will get by using objdump.
