[LLVMdev] Register class conversions
...hat can convert between the 64bit and 32 bit and back. So, if this situation is detected, can I specify for llvm to insert some sort of conversion instead of just aborting with: Register class of operand and regclass of use don't agree! Operand = 2 Op->Val = 01828560: f64,ch = PTRLOAD_f64 0182B7E0, 0182B4B0, 0182B868, 01828450 MI = %reg1028<def> = CMP_32 41, %reg1027 VReg = 1027 VReg RegClass size = 8, align = 8 Expected RegClass size = 4, align = 4 Fatal error, aborting. Both of these patterns are matched via tablegen, so I'm not sure how it is coming to this conclusi...

[LLVMdev] Register class conversions
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? 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
