XR/SDK

Self-hosting toolchain for the XR/station and Fox32 platforms.

Features a self-hosting compiler for the Jackal language, an assembler, a linker, and a multi-threaded build tool; all written in Jackal. These tools can run on any little-endian platform that has a C compiler, and also on the XR/17032 and Fox32 architectures.

Usage

To initially build the Jackal compiler, type ./bootstrap.sh to cause the "precompiled" C files to be built into the initial compiler at ./bin/jkl.exe. The custom build system will also be built at ./bin/xrbt.exe.

Typing ./buildall.sh [desired multithread count] will then do a "proper" build of all of the tools.

Subsequent compilations of the tools can be performed as:

./bin/xrbt.exe ./build.xrbt JOBS=[desired multithread count] [toolname]

Where toolname is one of the following choices:

Jackal           - The Jackal compiler.
XrBuildTool      - The build system.
XrAsm            - The assembler.
XrLink           - The linker.
XrDiskUpdateTool - The disk tool.

Implementation Plan

• Jackal -> C bootstrap transpiler.
• Self-hosted Jackal compiler with C, Fox32, and XR/17032 backends.
• Self-hosted build tool xrbt to replace make.
• New generic assembler written in Jackal with XR/17032 and Fox32 support.
• New linker written in Jackal with XR/17032 and Fox32 support.
• Disk image creation and partitioning tool. Also with support for formatting, reading, and writing AisixFS.
• xrbt support for automatically creating and updating rebuilt files in disk images if configured to do so.
• Complete rewrite of the MINTIA OS in Jackal.
• New middle-end and backends for the Jackal compiler, since those turned out suboptimal (it was my first time!).
