* snapshot: stupid debugging sessionKartik K. Agaram2021-04-052-1/+3
| | | | | | | | | | | | | | | I spent a while building a little keyboard scancode printer: $ ./translate ex1.mu && qemu-system-i386 disk.img ..and wondering why up-arrow was 0x48 in hex but 724 in decimal. I ended up paranoidly poking at a bunch of crap (though there _is_ a cool chromatography-based debugging technique in 126write-int-decimal.subx) before I realized: - 724 just has one extra digit over the correct answer - the 0xe0 scan code is a 3-digit number in decimal -- and the final digit is '4' There's nothing actually wrong.

Baremetal is now the default build target and therefore has its sources at the top-level. Baremetal programs build using the phase-2 Mu toolchain that requires a Linux kernel. This phase-2 codebase which used to be at the top-level is now under the linux/ directory. Finally, the phase-2 toolchain, while self-hosting, has a way to bootstrap from a C implementation, which is now stored in linux/bootstrap. The bootstrap C implementation uses some literate programming tools that are now in linux/bootstrap/tools. So the whole thing has gotten inverted. Each directory should build one artifact and include the main sources (along with standard library). Tools used for building it are relegated to sub-directories, even though those tools are often useful in their own right, and have had lots of interesting programs written using them. A couple of things have gotten dropped in this process: - I had old ways to run on just a Linux kernel, or with a Soso kernel. No more. - I had some old tooling for running a single test at the cursor. I haven't used that lately. Maybe I'll bring it back one day. The reorg isn't done yet. Still to do: - redo documentation everywhere. All the README files, all other markdown, particularly vocabulary.md. - clean up how-to-run comments at the start of programs everywhere - rethink what to do with the html/ directory. Do we even want to keep supporting it? In spite of these shortcomings, all the scripts at the top-level, linux/ and linux/bootstrap are working. The names of the scripts also feel reasonable. This is a good milestone to take stock at.
