[llvm-dev] infer correct types from the pattern

[Rail Shafigulin via llvm-dev]

i'm getting a

Could not infer all types in pattern!

error in my backend. it is happening on the following instruction:

VGETITEM:  (set GPR:{i32:f32}:$rD, (extractelt:{i32:f32}
VR:{v4i32:v4f32}:$rA, GPR:i32:$rB)).

how do i make it use appropriate types? in other words if it is f32 then
use v4v32 and if it is i32 then use v4f32. i'm not sure even where to start?

any help is appreciated.
