This patch: * Adds necessary RV64D codegen patterns * Modifies CC_RISCV so it will properly handle f64 types (with soft float ABI) Note that in general there is no reason to try to select fcvt.w[u].d rather than fcvt.l[u].d for i32 conversions because fptosi/fptoui produce poison if the input won't fit into the target type.
