If you had the register alias feature I described above, would
you be
ale to write such low-level manipulations using intrinsics?
I think I would be able to rewrite all x86 asm blocks I've ever
written
using that feature.
No, I couldn't. Such code involved stack manipulations that cannot
be emulated by such a feature.
Really?
Can you elaborate? Give me an example that couldn't be done with
register aliasing and intrinsics?
Walter gave you examples. You'll find many others in druntime.
Here is something I wrote recently that use this again :
