-Note that aside from MSVC on Windows, the [gcc vector extensions](https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html) (which are [implemented by clang](https://clang.llvm.org/docs/LanguageExtensions.html#vectors-and-extended-vectors)) are used to implement the SIMD operations. See `rpp/rpp/impl/simd.cpp`.
+Except for MSVC on Windows, the [gcc vector extensions](https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html) (also [implemented by clang](https://clang.llvm.org/docs/LanguageExtensions.html#vectors-and-extended-vectors)) are used to emit SIMD operations.
+On Linux, other architectures should therefore work, but they have not been tested.
 
 Other configurations (GCC, etc.) may be added in the future.
