Whee. Compiler stage3 now passes all tests that stage1 and stage2 do, when running the tests via the IR emulator.
Time to start improving the IR, allocating registers, and implementing a backend to generate "real" code from the IR.

git commit history for a couple changes tidying up the tree and splitting ir-types.spl into ir-instructions.spl and ir-blocks.spl
Blergh. Did a little tidying up, made a bigger mess, chased down the tiny one-line change that broke everything and hid in the noise, and put it all back together again.
Good: Everything's tidier.
Bad: Did not actually do the thing I set out to do this afternoon.

Abstraction:
It removes the need for
manual __syncthreads() calls,
as #compiler automatically
manages #thread-synchronization

Spent a few days playing with the game of life program, fixed a lot of bugs in the language doing so. I should make more projects like this to stress test the language, any ideas for what else I should try coding?

A snippet of my programming language showing anonymous structs, multiple return values, and tuples ``` fn multiple_returns(): struct { u32, u32 } { return { 6, 7 } } //accept as anonymous struct fn foo(struct { a: u32, b: u32}) { println(a) println(b) } //accept as tuple fn bar(tup: struct { u32, u32 }) { println(tup.0) println(tup.1) } fn main(): u32 { let x = multiple_returns() foo(x) bar(x) return 0 } ```
Anonymous structs have blown open a whole new slew of features. Multiple return values and tuples basically for free

A snippet of code in my programming language showing coercion between a named struct and an unnamed struct, as well as promotion of an anonymous struct's fields to the containing struct: ``` struct Foo { { a: u32, b: u32 } } struct Pair { a: u32, b: u32 } fn foo({a: u32, b: u32}, c: u32) { println(a, b, c) } fn main(): u32 { let pair = Pair { 1, 2 } foo(pair, 3) //named struct coerced to anonymous struct let f = Foo { pair } println(f.a) println(f.b) return 0 } ```
The output: ``` 1, 2, 3 1 2 ```
Been noodling on how my language will handle anonymous structs. They're not done yet but I think they'll be pretty loose, able to coerce between compatible named structs. Plus they'll basically act like tuples once you can create anonymous struct literals, which is nice!

Compiler directives give you fine‑grained control over the build process. Use #Pragma to toggle debug‑only code, profile performance hotspots, or conditionally compile for specific platforms (Desktop, Web, Mobile). Do you use any in your projects?

Two files in my language showing a barebones gameboy CPU and raylib draw loop with the gameboy window running, showing a blank screen
Getting to the point where I can write semi-serious programs in my language. It's a great way to find a bunch of subtle bugs and missing functionality. E.g. here's a ~totally functioning~ gameboy emulator

A program in my language showing function overloads: ``` struct Vec2 { x: u32, y: u32 } struct Vec3 { x: u32, y: u32, z: u32 } fn add(a: Vec2, b: Vec2): Vec2 { return Vec2 { a.x + b.x, a.y + b.y } } fn add(a: Vec3, b: Vec3): Vec3 { return Vec3 { a.x + b.x, a.y + b.y, a.z + b.z } } fn main(): u32 { let v2a = Vec2 { 3, 2 } let v2b = Vec2 { 4, 3 } let v2c = add(v2a, v2b) println(v2c) let v3a = Vec3 { 3, 2, 1 } let v3b = Vec3 { 2, 1, 1 } let v3c: Vec3 = add(v3a, v3b) println(v3c) return 0 } ```
The output of the program: ``` { 7, 5 } { 5, 3, 2 } ```
Had to implement some name mangling when emitting functions to lay the groundwork for interfaces, and I noticed this gave me function overloads for free. Take that, C!

Starting to get some credible looking (unoptimized) IR out of the stage3 compiler. Physical registers are dollar-prefixed, virtual registers percent-prefixed. The comments on the basic blocks are human-friendly tags to help see which part of the codegen they came from.

A snippet of my programming language showing optionals and early returns on optionals: ``` fn maybe(b: bool): ?u32 { if (b) return 10 return none } fn opt_return(b: bool): ?u32 { let x = maybe(b) println(x?) //if x is none, return here, else print the value of x (10) println("x was some!") return x } fn main(): u32 { let x = opt_return(true) if (x) |value| { println(value + 10) } else println("x was none") let y = opt_return(false) if (y) |value| { println(value + 10) } else println("y was none") return 0 } ```
The output of the program: ``` 10 x was some! 20 y was none ```
It's all coming together. Now I have unions I can implement the optional type ?T which is just a tagged union. In addition I could implement rust style try-unwrap of optionals basically for free with all the parts I have!
Here opt_return only prints x if it's some, else it returns early!

Now with the fancy struct syntax, implementing tagged unions was relatively easy. Also got rid of all those pesky semicolons messing up the place

Xcode Swift: “expression too complex to resolve…”
So, you’re saying the language is non-deterministic and too convulsed even for a compiler… Gotcha!
My bane in using Swift. You have to jump through hoops and invent non-existent curses to resolve the error.
