* mostly done with emit-outputKartik Agaram2019-07-091-6/+131
| | | | | Some nooks and crannies will need light final debugging with xxd, but emit-hex-output covers most of the logic.
* done with emit-segmentsKartik Agaram2019-07-091-33/+532
| | | | Only failures now are the first two tests in survey.subx.

* preserve truthiness of non-booleansKartik Agaram2019-07-091-16/+12
| | | | | Everywhere we check if something is true, we check it by comparing against 0, not 1.
* this looks like a bugKartik Agaram2019-07-091-1/+1
| | | | | But of course the test is still infinite-looping so we can't be sure. I'm still just reading the code.

* move 'segment-start' to a global variable as wellKartik Agaram2019-07-091-12/+10
| | | | | It's ugly to have function locals in global variables, but we'll figure out later how to deal with it.

* there's a variant of compute-width for slicesKartik Agaram2019-07-091-9/+5
| | | | | Looks like the original compute-width is now dead. But still seems useful to have around.
* there's a variant of get-or-insert for slicesKartik Agaram2019-07-091-27/+16
| | | | | | The compute-offsets test now goes into an infinite loop :( But I figure all these changes are useful anyway, we should just debug the error separately.
* keep labels definitions on a separate lineKartik Agaram2019-07-091-6/+12
| | | | SubX in SubX doesn't support mixing labels with other stuff :)

| | | | | Be more consistent about names of ends of a slice. (In the opposite direction compared to last night's 925fc490d2ce8b8d411de87bd0af5b3a8a704213.)

| | | | | | 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.
