Summary: Structs aren't alligned on stack
Product: D
Version: 1.027
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: baryluk mpi.int.pl
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.
