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

Use
```
-masm=intel
```
```
```
gcc -S -masm=intel -Og -fverbose-asm test.c
```
```
That works with GCC, and clang3.5 and later.
GCC manual
:
```
-masm=dialect
```
Output asm instructions using selected dialect.  Supported choices
are intel or att (the default one).  Darwin does not support intel.
For Mac OSX, note that by default, the
```
gcc
```
command actually runs clang.  Modern clang supports
```
-masm=intel
```
as a synonym for this, but
this always works with clang
:
```
```
clang++ -S -mllvm --x86-asm-syntax=intel test.cpp
```
```
Note that
until clang 14
, this does
not
change how clang processes inline
```
asm()
```
statements,
unlike for GCC
.
These are the options used by Matt Godbolt's Compiler Explorer site by default:
