* 6887Kartik Agaram2020-09-276-327/+327
| | | | | subx.md distinguishes between operands and arguments. Let's use that terminology more consistently in the sources.

* 6885 - starting on floating-point instructionsKartik Agaram2020-09-274-10/+115
| | | | | | | | | I spent some time deciding on the instructions. x87 is a stack ISA, so not a good fit for the rest of SubX. So we use SSE instead. They operate on 32-bit floats, which seems like a good fit. SSE has a bunch of instructions for operating on up to 4 floats at once. We'll ignore all that and just focus on so-called scalar instructions.

|
* 6880Kartik Agaram2020-09-261-2/+25
| | | | | We need the state of the stack at the call-site. But rendering is already working surprisingly well.
* 6879Kartik Agaram2020-09-261-14/+18
| | | | Extract a new function.

* 6877Kartik Agaram2020-09-262-2/+26
| | | | Track just whether to step inside or not.
* 6876Kartik Agaram2020-09-263-53/+10
| | | | Back to commit 6872.
* 6875Kartik Agaram2020-09-262-1/+29
| | | | | Snapshot. Caching subsidiary stacks is a dead end; they're just the final iteration. We need to render all iterations.

| | | | Now saving the subsidiary stack.
* 6872Kartik Agaram2020-09-261-0/+2
| | | | Hackily show function definition.
* 6871Kartik Agaram2020-09-262-2/+3
| | | | Segfault now fixed. Everything seems to be working again.
* 6870Kartik Agaram2020-09-266-65/+103
| | | | | | Emit a stack of not ints but more complex objects containing the int payload. Function calls again segfaulting.

* 6868Kartik Agaram2020-09-263-17/+81
| | | | First function call working in apps/tile!
* 6867Kartik Agaram2020-09-261-2/+5
| | | | Segfault fixed. This shouldn't have been so hard.

* 6860Kartik Agaram2020-09-267-12/+152
| | | | | Snapshot: tile currently segfaulting. I need to back up and make it easier to debug.

| | | | | Get rid of cutesy justify thresholds. They didn't actually save me any trouble, and they won't generalize to other literals besides ints.

| | | | I actually deleted a test here! Hard-core prototype mode.
* 6843Kartik Agaram2020-09-231-0/+5
| | | | Some keymappings to protect my pinky.
* 6842 - hackily load local Vim settingsKartik Agaram2020-09-233-0/+6
| | | | | | I have scripts to load vimrc.vim from the directory of the file being edited. This hack loads vimrc.vim from the top-level mu/ directory when I edit files in some common directories.
* 6841Kartik Agaram2020-09-221-0/+9
| | | | Initial sketch for a menu bar.
* 6840Kartik Agaram2020-09-221-8/+17
| | | | Extract "unmoving background" into a separate function.
* 6839Kartik Agaram2020-09-221-2/+1
| | | | Not sure what I was seeing. clear-screen is plenty stable.
* 6838Kartik Agaram2020-09-222-1/+43
| | | | | | Interestingly, erasing the screen partially looks better to me even though it's clearly slower. The divider never being redrawn provides a sense of stability.
