Some nooks and crannies will need light final debugging with xxd, but
emit-hex-output covers most of the logic.
|
| |
|
|
| |
Only failures now are the first two tests in survey.subx.
|
| | |
|
| |
|

|

Everywhere we check if something is true, we check it by comparing
against 0, not 1.
|
| |
|
|
|
| |
But of course the test is still infinite-looping so we can't be sure.
I'm still just reading the code.

It's ugly to have function locals in global variables, but we'll figure
out later how to deal with it.
|

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.

Move test slice variables out of the data segment and close to their
usages. Makes tests a little easier to read even if we spend a few more
instructions each time.

DRY out compute-width and compute-width-from-slice.

Now the only piece I plan to not write tests for is emit-headers.

Fix a couple of syntax errors.
survey.subx still failing tests.

subx/survey/compute-addresses: Now computing segment starting addresses
correctly.
|
| | |
|
| |
|
|
| |
Now tracing segment names correctly.

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.

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.

No trace statements yet, so we don't know if it works.
|

Flesh out final test some more. We also now have a new family of
primitives for writing non-strings to input streams in tests.

Simplify `string-equal`.

'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.

Start of the final phase needed to implement SubX in SubX:
$ cat files.subx ... |dquotes |assort |pack |survey |hex > a.elf
survey.subx is responsible for assigning addresses to labels and segments.
