## Message

```
riscv: basic struct field access

the current implementation only works when the struct is in a register. we use some shifting magic
to get the field into the LSB, and from there, given the type provenance, the generated code should
never reach into the bits beyond the bit size of the type and interact with the rest of the struct.

```
