* 6041 - array indexing starting to workKartik Agaram2020-02-215-10/+124
| | | | | | | | | | | | | And we're using it now in factorial.mu! In the process I had to fix a couple of bugs in pointer dereferencing. There are still some limitations: a) Indexing by a literal doesn't work yet. b) Only arrays of ints supported so far. Looking ahead, I'm not sure how I can support indexing arrays by non-literals (variables in registers) unless the element size is a power of 2.

| | | | | | Changing `switchbuf` globally is too heavyweight a change just to do the right thing when hitting `:T`. I don't even use it anymore since I got `<Leader>t`; why was I hitting `:T` just to navigate to `last_run`, again?

|
* 6023 - bug: vars with both stack-offset and regKartik Agaram2020-02-182-10/+20
| | | | | This was initially disquieting; was I writing enough tests? Then I noticed I had TODOs for some missing checks.
* 6022 - initial sketch of array lengthKartik Agaram2020-02-182-0/+75
| | | | | This is a particularly large abstraction leak: SubX arrays track their lengths in bytes, and therefore Mu as well.
* 6022Kartik Agaram2020-02-182-1/+4
| | | | Forgot to actually use the new type-dispatch in commit 6017.

| | | | Some deduplication, though this may be a premature abstraction.
* 6019 - finish supporting all branch primitivesKartik Agaram2020-02-184-10/+238
| | | | | | | | I'd been thinking I didn't need unconditional `break` instructions, but I just realized that non-local unconditional breaks have a use. Stop over-thinking this, just support everything. The code is quite duplicated.

* 6017 - simplify type-dispatch for primitivesKartik Agaram2020-02-172-26/+66
| | | | | | | | | | | | We'll be doing type-checking in a separate phase in future. For now we need only to distinguish between literals and non-literals for x86 primitive instructions. I was tempted to support x86 set__ instructions for this change: https://c9x.me/x86/html/file_module_x86_id_288.html That will happen at some point. And I'll simplify a bunch of branches for results of predicate functions when it happens.

* 6009 - significantly cleaner lexingKartik Agaram2020-02-163-135/+34
| | | | | | | | | This cleans up a bunch of little warts that had historically accumulated because of my bull-headedness in not designing a grammar up front. Let's see if the lack of a grammar comes up again. We now require that there be no space in variable declarations between the name and the colon separating it from its type.
* 6008Kartik Agaram2020-02-163-19/+20
| | | | | | | | Allow comments at the end of all kinds of statements. To do this I replaced all calls to next-word with next-mu-token.. except one. I'm not seeing any bugs yet, any places where comments break things. But this exception makes me nervous.

| | | | | | | | Support calling SubX code from Mu. I have _zero_ idea how to make this safe. Now we can start writing tests. We can't use commandline args yet. That requires support for kernel strings.
