I'm looking for the D inline assembler equivalent of the

Here's more information:

I tried searching through a turbo assembler tutorial (because
D's is based on it) and found nothing except a few hints here:
http://www.csn.ul.ie/~darkstar/assembler/manual/a10.txt
There might be a way through segments, directives, but I'm not
sure at all if D supports it.
Does anyone have any idea if/how I can align my code this way
or if the compiler handles it?
As far as I understand, `.p2align 4,,15` aligns to a 16 byte
boundary, and the third argument could be left out, because more
than 15 bytes wouldn't ever be skipped anyway.
D inline assembler has an 'align' directive [1]. Aligning to a 16
byte boundary in D: `align 16;`.
