How do you use gcc to generate assembly code in Intel syntax?

The gcc -S option will generate assembly code in AT&T syntax, is there a way to generate files in Intel syntax? Or is there a way to convert between the two?

Solution 1:

Have you tried this?

gcc -S -masm=intel test.c

Untested, but I found it in this forum where someone claimed it worked for them.

I just tried this on the mac and it failed, so I looked in my man page:

   -masm=dialect
       Output asm instructions using selected dialect.  Supported choices
       are intel or att (the default one).  Darwin does not support intel.

It may work on your platform.

For Mac OSX:

clang++ -S -mllvm --x86-asm-syntax=intel test.cpp

Solution 2:

The

gcc -S -masm=intel test.c

Does work with me. But i can tell another way, although this has nothing to do with running gcc. Compile the executable or the object code file and then disassemble the object code in Intel asm syntax with objdump as below:

 objdump -d --disassembler-options=intel a.out

This might help.
