How do I compile the asm generated by GCC?

Question

I\'m playing around with some asm code, and something is bothering me.

I compile this:

#include 

int main(int argc, char** argv){
  p

gcc can use an assembly file as input, and invoke the assembler as needed. There is a subtlety, though:

• If the file name ends with ".s" (lowercase 's'), then gcc calls the assembler.
• If the file name ends with ".S" (uppercase 'S'), then gcc applies the C preprocessor on the source file (i.e. it recognizes directives such as #if and replaces macros), and then calls the assembler on the result.

So, on a general basis, you want to do things like this:

gcc -S file.c -o file.s
gcc -c file.s
