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/bootstrap/build_and_test_until | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100755 linux/bootstrap/build_and_test_until (limited to 'linux/bootstrap/build_and_test_until') diff --git a/linux/bootstrap/build_and_test_until b/linux/bootstrap/build_and_test_until new file mode 100755 index 00000000..6f0782e1 --- /dev/null +++ b/linux/bootstrap/build_and_test_until @@ -0,0 +1,18 @@ +#!/bin/sh +# Run tests for just a subset of layers. +# +# Usage: +# build_and_test_until [file prefix] [test name] +# Provide the second arg to run just a single test. +set -e + +# clean previous builds if they were building until a different layer +touch .until +PREV_UNTIL=`cat .until` +if [ "$PREV_UNTIL" != $1 ] +then + ./clean top-level + echo $1 > .until +fi + +./build --until $1 && ./bootstrap_bin test $2 -- cgit 1.4.1-2-gfad0
