 ## Use AT&T syntax by default on x86
 
-x86 is particular in that there are [two widely used dialects] for its assembly code: Intel syntax, which is the official syntax for x86 assembly, and AT&T syntax which is used by GCC (via GAS). There is no functional difference between those two dialects, they both support the same functionality but with a [different syntax][gas-syntax]. This RFC chooses to use Intel syntax by default since it is more widely used and users generally find it easier to read and write.
