Introduction to Wave v0.1.1-pre-beta: Inline Assembly, Pointer Chain, and Array Support

Hello! I'm LunaStev, the developer of Wave.

We are excited to announce Wave v0.1.1-pre-beta — This update introduces inline assembly (asm {}) support, enabling you to write low-level system code directly in Wave, such as making syscalls with direct register manipulation.

Additionally, Wave now fully supports pointer chaining (ptr<ptr<i32>>) and array types (array<T, N>), including index access, address-of operations, and validation of literal lengths — expanding Wave's capability for systems-level and memory-safe programming.

These improvements bring Wave closer to its vision as a low-level but expressive programming language.

✅ Added Features

⚙️ Inline Assembly (asm { ... }) Support

  • Introduced asm { ... } block syntax to embed raw assembly instructions directly within Wave code.

  • Supports instruction strings (e.g., "syscall") and explicit register constraints via in("reg") var and out("reg") var.

  • Variables used in in(...) are passed into specified registers; variables in out(...) receive output from registers.

  • Supports passing literal constants directly to registers (e.g., in("rax") 60).

  • Pointer values (e.g., ptr<i8>) are correctly passed to registers such as rsi, enabling low-level syscalls like write.

  • Internally leverages LLVM's inline assembly mechanism using Intel syntax.

  • Currently supports single-output only; multiple out(...) constraints will overwrite each other.

  • Does not yet support clobber lists or advanced constraint combinations.

  • Provides essential capability for system-level programming (e.g., making direct syscalls, writing device-level code).

⚠️ This is not a fully general-purpose inline ASM facility yet, but it enables practical low-level operations within Wave. Full support is planned for later phases.

⚙️ Make pointer chain explicit

  • Nested parsing like ptr<i32>, ptr<ptr<i32>>

  • Can create ptr<T> for any type (no restrictions on T)

  • Support for consecutive deref operations (e.g., deref deref deref)

⚙️ Array type complete

  • IndexAccess (numbers[0]) handling

  • ArrayLiteral → Parse into AST and validate length

  • AddressOf → Support array literals with address-of values (e.g., [&a, &b])

  • Confirmed that array<T, N> supports any type as T

✨ Other Changes

🧠 Library and Binary 2 Coexist

  • Add lib.rs for easy package manager creation, development, and easy access.
