font-family:Arial'>Is there a simple way to specify the relationship between
two different register classes of various sizes and alignments as being legal
to convert between them? <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have my backend written up using a single register class
for i32, i64, f32 and f64 types, however, because the type information is not propagated
down to the machine instruction register level, it is not known to me how to
determine which data type my current register is. In working on moving to using
4 separate register classes I ran into the problem where some of my setup code needs
the larger type and not the smaller type.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> So is it possible to have the register class I have setup
for i32 type be automatically converted to the generic register type instead of
aborting?<o:p></o:p></span></font></p>
