Matthias Krüger c29fb2e57e Rollup merge of #144197 - KMJ-007:type-tree, r=ZuseZ4 
TypeTree support in autodiff

# TypeTrees for Autodiff

## What are TypeTrees?
Memory layout descriptors for Enzyme. Tell Enzyme exactly how types are structured in memory so it can compute derivatives efficiently.

## Structure
```rust
TypeTree(Vec<Type>)

Type {
    offset: isize,  // byte offset (-1 = everywhere)
    size: usize,    // size in bytes
    kind: Kind,     // Float, Integer, Pointer, etc.
    child: TypeTree // nested structure
}
```

## Example: `fn compute(x: &f32, data: &[f32]) -> f32`

**Input 0: `x: &f32`**
```rust
TypeTree(vec![Type {
    offset: -1, size: 8, kind: Pointer,
    child: TypeTree(vec![Type {
        offset: -1, size: 4, kind: Float,
        child: TypeTree::new()
    }])
}])
```

**Input 1: `data: &[f32]`**
```rust
TypeTree(vec![Type {
    offset: -1, size: 8, kind: Pointer,
    child: TypeTree(vec![Type {
        offset: -1, size: 4, kind: Float,  // -1 = all elements
        child: TypeTree::new()
    }])
}])
```

**Output: `f32`**
```rust
TypeTree(vec![Type {
    offset: -1, size: 4, kind: Float,
    child: TypeTree::new()
}])
```

## Why Needed?
- Enzyme can't deduce complex type layouts from LLVM IR
- Prevents slow memory pattern analysis
- Enables correct derivative computation for nested structures
- Tells Enzyme which bytes are differentiable vs metadata

## What Enzyme Does With This Information:

Without TypeTrees (current state):
```llvm
; Enzyme sees generic LLVM IR:
define float ``@distance(ptr*`` %p1, ptr* %p2) {
; Has to guess what these pointers point to
; Slow analysis of all memory operations
; May miss optimization opportunities
}
```

With TypeTrees (our implementation):
```llvm
define "enzyme_type"="{[]:Float@float}" float ``@distance(``
    ptr "enzyme_type"="{[]:Pointer}" %p1,
    ptr "enzyme_type"="{[]:Pointer}" %p2
) {
; Enzyme knows exact type layout
; Can generate efficient derivative code directly
}
```

# TypeTrees - Offset and -1 Explained

## Type Structure

```rust
Type {
    offset: isize, // WHERE this type starts
    size: usize,   // HOW BIG this type is
    kind: Kind,    // WHAT KIND of data (Float, Int, Pointer)
    child: TypeTree // WHAT'S INSIDE (for pointers/containers)
}
```

## Offset Values

### Regular Offset (0, 4, 8, etc.)
**Specific byte position within a structure**

```rust
struct Point {
    x: f32, // offset 0, size 4
    y: f32, // offset 4, size 4
    id: i32, // offset 8, size 4
}
```

TypeTree for `&Point` (internal representation):
```rust
TypeTree(vec![
    Type { offset: 0, size: 4, kind: Float },   // x at byte 0
    Type { offset: 4, size: 4, kind: Float },   // y at byte 4
    Type { offset: 8, size: 4, kind: Integer }  // id at byte 8
])
```

Generates LLVM:
```llvm
"enzyme_type"="{[]:Float@float}"
```

### Offset -1 (Special: "Everywhere")
**Means "this pattern repeats for ALL elements"**

#### Example 1: Array `[f32; 100]`
```rust
TypeTree(vec![Type {
    offset: -1, // ALL positions
    size: 4,    // each f32 is 4 bytes
    kind: Float, // every element is float
}])
```

Instead of listing 100 separate Types with offsets `0,4,8,12...396`

#### Example 2: Slice `&[i32]`
```rust
// Pointer to slice data
TypeTree(vec![Type {
    offset: -1, size: 8, kind: Pointer,
    child: TypeTree(vec![Type {
        offset: -1, // ALL slice elements
        size: 4,    // each i32 is 4 bytes
        kind: Integer
    }])
}])
```

#### Example 3: Mixed Structure
```rust
struct Container {
    header: i64,        // offset 0
    data: [f32; 1000],  // offset 8, but elements use -1
}
```

```rust
TypeTree(vec![
    Type { offset: 0, size: 8, kind: Integer }, // header
    Type { offset: 8, size: 4000, kind: Pointer,
        child: TypeTree(vec![Type {
            offset: -1, size: 4, kind: Float // ALL array elements
        }])
    }
])
```

run-make: update test suite README
2025-03-02 05:56:56 +08:00

README.md

The run-make test suite

The run-make test suite contains tests which are the most flexible out of all the rust-lang/rust test suites. run-make tests can basically contain arbitrary code, and are supported by the run_make_support library.

Infrastructure

A run-make test is a test recipe source file rmake.rs accompanied by its parent directory (e.g. tests/run-make/foo/rmake.rs is the foo run-make test).

The implementation for collecting and building the rmake.rs recipes are in src/tools/compiletest/src/runtest.rs, in run_rmake_test.

The setup for the rmake.rs can be summarized as a 3-stage process:

  1. First, we build the run_make_support library in bootstrap as a tool lib.

  2. Then, we compile the rmake.rs "recipe" linking the support library and its dependencies in, and provide a bunch of env vars. We setup a directory structure within build/<target>/test/run-make/

    <test-name>/
    rmake.exe              # recipe binary
    rmake_out/             # sources from test sources copied over

    and copy non-rmake.rs input support files over to rmake_out/. The support library is made available as an extern prelude.

  3. Finally, we run the recipe binary and set rmake_out/ as the working directory.
