📝 Walkthrough

Walkthrough

A new harm! macro sequences instruction appends on an assembler and returns the first error or Ok(()). The macro is exported and re-exports Assembler and AssemblerError at crate root; two unit tests were updated to use the macro. A minor enum formatting change was made.

Changes

Instruction Sequencing Macro

Layer / File(s)	Summary
Macro Definition and Test harm-runtime/src/macros.rs	harm! macro accepts an assembler and instruction sequence, appends each instruction, and propagates the first error or returns Ok(()). Dedicated feature-gated test exercises the macro with two instructions.
Crate-Level Re-exports harm-runtime/src/lib.rs	Module macros declared with #[macro_use]; Assembler and AssemblerError re-exported from runtime at crate root.
Test Refactoring harm-runtime/src/runtime.rs	Two unit tests (test_assembler_build, test_assembler_aarch64_execute) replace explicit asm.append() chains with single harm! { asm; ... } blocks followed by .unwrap().
Formatting harm-runtime/src/runtime.rs	Blank line added in AssemblerError enum between PositionedMemory and ExecutableMemory variants.

Lined up insts to stream them right,
One macro call to bind the queue,
Errors surface, builds run true,
