lewis-revill added a parent revision: D74977: [WIP][RISCV][GlobalISel] Add lowerFormalArguments for calling convention.

This patch implements minimal support for lowering function calls to callees with arguments and/or return values according to the RISC-V calling convention. Simple non-aggregate types are supported. Lowering according to fastcc calling convention is not yet supported.

This patch is work in progress - many cases are not covered yet but feedback is very much appreciated.
