How can I compile to assembly with gcc
c, gcc, linux, x86
Solution
I suggest also using `-fverbose-asm` because then the generated assembler has some generated comments which "explains" the code. For example:
gcc -S -fverbose-asm -O2 foo.c
would generate in `foo.s` (with some comments) the assembler code produced by compiling `foo.c`
And to understand what the GCC optimizations are doing one could even try `-fdump-tree-all` (but this produces hundreds of files!).
Problem
How do I compile to assembly instead of an executable with gcc. I know there is an -S flag, but where do I use it in the makefile. For example, if I use flags -O3 -o exe_name, where should I put the -S flag?
