| | | | | | Make `compute-addresses` less clever. Stop striding from the middle of one row to the next. This way we'll also obviate the need for indexing backwards from a pointer in the next commit.
* some primitives for emitting tracesKartik Agaram2019-07-011-1/+447
| | | | | | | | | | | | | | Kinda hacky, but might scale enough for machine code. This was really hard to debug. Single tests passed, but when I ran all tests I got breakage because tests long before (from the 056trace layer) were not cleaning up properly. My instinct was to call clear-stream on Trace-stream, which was wrong (the trace didn't have the wrong contents, it was literally a bad object). It was also wrong in a counter-productive way: calling clear-stream on a real Trace stream (which is the size of a page of memory) takes a long time in emulated mode.

* initial draft of solution for 'compute-addresses'Kartik Agaram2019-06-281-4/+73
| | | | No trace statements yet, so we don't know if it works.
* .Kartik Agaram2019-06-281-12/+155
| | | | | Flesh out final test some more. We also now have a new family of primitives for writing non-strings to input streams in tests.

| | | | | Now that we don't have to edit code to run a single test, delete that commented out fragment everywhere.

| | | | | | 'get-or-insert-stream' is now the more generic 'get-or-insert' that can handle tables of any value type. But callers have to be careful to cast values to the right type.
