Description Witold Baryluk 2008-02-17 12:32:58 UTC 
This is quite important bug, because SSE on x86 needs data alligned to 16 bytes bonduary. Using opcodes for not alligned data is very slow, and sometimes isn't even posible.

Implementation can be quite tricky. gcc team created special branch for automatic stack alligment: http://gcc.gnu.org/ml/gcc/2008-01/msg00282.html . similar idea can be used in dmd for proper aligment.

This bug report is for tracking purpose.

1.027 isn't out yet. And this is an enhancement request, not a bug.
