* periodic run of misc_checksKartik K. Agaram2021-06-121-2/+2
| | | | | I should really stop using /disp8 jumps at the top-level given how inconvenient it is to check for overly large offsets.
* more robust print-cellKartik K. Agaram2021-05-191-0/+86
| | | | | It is used to print to the trace, and we shouldn't crash the whole computer just because the trace ran out of space.
* print call stack on all low-level errorsKartik K. Agaram2021-05-151-3/+1

* first passing test for macroexpandKartik K. Agaram2021-05-061-1/+9
| | | | | | | | In the process I spent a long time tracking down a stray TODO in 108write.subx that I thought would abort but didn't since the switch to baremetal. Then after I reintroduced that assertion I had to go track down a bunch of buffer sizes. Stream sizes continue to be a huge mess.
* 7842 - new directory organizationKartik K. Agaram2021-03-031-30/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* 7101 - tile: remove quotes when evaluating stringsKartik Agaram2020-10-251-0/+3
| | | | This found several bugs due to me not checking for null strings.
