Cod generation for different targets ( x386, x486 etc )

[Timofei Bolshakoc]

I am using D ver. 2 for more then a year - since version 2.051. 
My target architecture is Linux on Vortex DX SoC - 
http://www.vortex86sx.com/?page_id=197
It is compatible with x586 architecture. Till version 2.057 
everything was OK, but when I recompiled my working code with 
2.057 VERY strange behaviour was observed - I can't even describe 
it correctly. I think that something was broken in floating point 
support. I returned to version 2.056.

So, the question is - can I generate code for different x86 
targets - x486, x586, x686 etc using dmd. I like dmd and do not 
want to switch to gdc if it will be possible to stay on dmd. I 
did not tried 2.058 yet - please tell me if I should.
