Easy way to convert c code to x86 assembly?

Question

Is there an easy way (like a free program) that can covert c/c++ code to x86 assembly?

I know that any c compiler does something very similar and that I can just compile

Answer 1

Gcc can do it with the -S switch, but it will be disgustingly ugly at&t syntax.

Answer 2

The lcc compiler is a multiplatform cross-compiler. You can get it to produce Intel syntax assembly code by

lcc -S -Wf-target=x86/win32 foo.c

I find assembly code from lcc significantly easier to read than what gcc spits out nowawadays.

Answer 3

Your compiler is already doing that as you've stated, and most likely will have an option to stop before assembling.

For GCC, add the -S flag.

gcc -S x.c
cat x.s

Edit: If your program is pretty short, you could use the online service at https://gcc.godbolt.org/.

Answer 4

GCC can output Intel syntax assembly using the following command line:

gcc -S input.c -o output.asm -masm=intel

Answer 5

gcc will generate assembly if you pass it the -S option on the command line.

Microsoft Visual C++ will do the same with the /FAs option.

Answer 6

notice every architecture has its own unique names and even build differently now when you know the stacks involved using asm volatile would b the perfect solution
