'curr-segment-name' is now a string, and it's stored in a register
rather than a global.
Paradoxically, this leaks *less* than before. Before, every call to
`get-or-insert-slice` leaked memory. Now we leak one string for every
new segment. Which is trivial.
|
| |
|
|
|
|
|
| |
Pseudocode is a little more truthful now about what variables are on the
stack.
|
|
|

It's a slice into the 'line' stream. But we want to preserve the current
segment name across lines.
Let's leak some memory.

|

Make the trace a little more consistent.

I changed the test a little to make it obvious.
Basically there's no way we can compute the segment offset correctly
without knowing the segment name in the previous assertion.

The pseudocode was a mess here :/ I was saving the segment-offset but
tracing the file-offset.
Segments need file offsets (to tweak their starting address).
Labels need segment offsets (to add to segment starting address).

I think we're calling the wrong variant here.

This was why grep required the `-a` argument in vimrc.vim.

Another batch of incorrectly signed conditional jumps. (Follow-up to
commit 5180.)

Fix infinite loop in the 2 remaining failing tests; now it's a segfault.

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.

Leads to a bad error message.

Stop dumping huge traces on error. We can always rerun with --trace.
Though perhaps we should just dump the trace automatically on error.
Not bothering thinking about that right now.

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.

Looks like the original compute-width is now dead. But still seems
useful to have around.
|
|
|
|
|
|
| |
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.

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.)

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.
