Yes, but...
Assembly use case is just very low now.

I wrote a lot of assembly and since the modern backends like in 
ICC, LLVM or GCC since v4 it doesn't make a lot of sense to have 
code that doesn't perform better, is much harder to maintain, 
read and write.

If anything, optimising a bottleneck with intrinsics takes 3x 
more time, translating it back once the truth unfold is 
error-prone too.

The **inlinable** GCC-style assembly is actually more suitable to 
create the low-level abstracted things that can be used instead 
of assembly. That is, if you manage to write it ^^
