调研方向

Start by reproducing the failure in the issue’s Wave source and inspect the Wave adapter’s typed-pointer lowering alongside upstream Whale’s tracked-memory/GEP and provenance rules. Verify scalar pointer signatures, loads/stores, element stride, casts, null behavior, unsupported conversions, and memory boundaries using available upstream facilities; completion requires these cases while leaving C ABI and native lowering out of scope. Discuss the design with @LunaStev before implementation.

描述

discussion enhancement help wanted

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 type Pointer(Int(32)):

fun identity(x: ptr<i32>) -> ptr<i32> { return x; }

Scope

Add typed pointers, address-of/dereference and HIR-defined pointer offsets to the Wave adapter. Inspect upstream tracked-memory/GEP and provenance rules first. Preserve Wave stride, null and cast behavior; pointer-to-bool remains unsupported. Do not implement C ABI or native lowering here; upstream frontend #156 is separate.

Difficulty: hard.

Completion criteria

  • Verify scalar pointer signatures, loads/stores and element stride.
  • Cover casts, null and existing unsupported conversions.
  • Test memory boundaries with available upstream facilities.

Please mention @LunaStev to discuss the design before starting implementation.
