| | | | | | Fix a stack bug in survey_baremetal. I'm not sure how my tests weren't crashing, but I won't bother digging further. | |||||

* | bugfix in mandelbrot-fixed | Kartik K. Agaram | 2021-05-09 | 1 | -13/+19 | |
| | | | | | | | | Thanks to comparing regular ints with fixed-point ints, I was computing iterations for many screenfuls of pixels to the right of the current one. (Y-axis behaved similarly, but there it was just doing other work instead of busy-looping forever. If you don't have anything else to do, it doesn't matter what you do.) | |||||

| | | | | | | Basically this should never, ever happen until I start reclaiming heap memory. I believe the only reason it happens is unprotected writes to address 0 or thereabouts. | |||||

| | | | | | | | | | | | | | | | Another commit, another bugfix. Some snippets from my currently exploding todo list: - always investigate lookup errors immediately. Beyond the root cause, they should never happen at the moment, while we aren't reclaiming memory. we should always return a more precise error message. Usually involving null pointer checks. - on abort, print out stack trace - emit mapping of labels to addresses during survey - store a mapping of symbols somewhere in the code image - stop allocating 1KB per token; expand space for tokens as needed | |||||

* | first passing test for macroexpand | Kartik K. Agaram | 2021-05-06 | 6 | -41/+249 | |
| | | | | | | | | 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. | |||||

| | | | | | | | | | | | Current plan: - some way to define macros. For now: (def f (litmac litfn () (a b) `(+ ,a , b))) - macroexpand will expand calls by passing them through the cdr (f 3 4) macroexpand: ((litfn () (a b) `(+ ,a ,b)) 3 4) => (+ 3 4) eval: (+ 3 4) => 7 |
