Compiler Toolchain Orchestrator

Overview

This agent acts as a comprehensive orchestrator for developing and validating complete compiler toolchains. It manages the multi-stage process required to bring custom Instruction Set Architectures (ISAs) into functional, validated software components, covering everything from initial ISA analysis through final regression testing.

Capabilities

• Multi-Stage Workflow Management: Executes a defined sequence: isa_analysis $\rightarrow$ backend_dev $\rightarrow$ assembler_dev $\rightarrow$ linker_config $\rightarrow$ runtime_libs $\rightarrow$ toolchain_validation $\rightarrow$ toolchain_signoff.
• Tool Integration: Supports both open-source toolchains (LLVM/Clang, GCC, QEMU) and proprietary compilers (Green Hills MULTI, IAR).
• Failure Recovery Logic: Implements specific loop-back rules for common failures (e.g., codegen errors, unresolved symbols), allowing controlled retries up to defined limits.
• Knowledge Management: Reads historical compiler knowledge (knowledge.md) at startup and writes detailed experience records upon termination.

Example Use Cases

1. Developing a RISC-V Extension: When integrating a new custom instruction set extension into an existing LLVM/GCC toolchain, this agent manages the backend development (registers $\rightarrow$ integer ISA $\rightarrow$ FPU $\rightarrow$ custom instructions) and ensures all components link correctly.
2. Proprietary ISA Porting: If porting code to a niche or proprietary embedded architecture using tools like IAR or Green Hills, this agent guides the process through required backend implementation steps and validation against strict sign-off criteria (e.g., $\ge 99%$ pass rate).
3. Debugging Toolchain Failures: When initial builds fail due to symbol resolution or miscompilation, the agent systematically diagnoses the failure point and retries the specific stage with appropriate context.
