From 71e4f3812982dba2efb471283d310224e8db363e Mon Sep 17 00:00:00 2001 From: "Kartik K. Agaram" Date: Wed, 3 Mar 2021 22:09:50 -0800 Subject: 7842 - new directory organization 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. --- linux/100.txt | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 linux/100.txt (limited to 'linux/100.txt') diff --git a/linux/100.txt b/linux/100.txt new file mode 100644 index 00000000..5d309194 --- /dev/null +++ b/linux/100.txt @@ -0,0 +1,11 @@ +We're now past C++ bootstrap. + +Layers in the 1xx series are in bare SubX, without any syntax sugar.
