调研方向
Start with whale/src/codegen/mod.rs and whale/src/codegen/walk.rs, then discuss the design with @LunaStev before implementation. Verify struct construction, field reads and writes, and nested structs while preserving layout, conversions, and evaluation order; keep unsupported external C ABI boundaries explicit. The issue is complete when those checks pass without weakening recursive-layout checks or duplicating upstream native aggregate ABI work.

描述
Motivation
At fd07427f4a976de05e38eff3ee1760db97fbb761 on Linux amd64 with Rust 1.89 and locked Whale 020d2a4, lexing, parsing and TypedProgram lowering succeed, but calling whale::emit_ir on this source returns Whale backend does not yet support non-function top-level declarations:
struct Pair { x: i32; y: i32; } fun main() -> i32 { return 0; }
Scope
Support Wave struct metadata, values and field access using frontend-resolved types/layout. Separate internal aggregate lowering from external C ABI classification. Do not weaken recursive-layout checks or duplicate upstream native aggregate ABI work. Starting points: whale/src/codegen/mod.rs and whale/src/codegen/walk.rs.
Difficulty: hard.
Completion criteria
- Verify construction, field reads/writes and nested structs.
- Preserve layout, field conversions and evaluation order.
- Keep unsupported external ABI boundaries explicit.
Please mention @LunaStev to discuss the design before starting implementation.
Related pointer adaptation: #879; external C ABI work remains separate.
