# Autodiff Type-Trees Type Analysis Tests

This directory contains run-make tests for the autodiff type-trees type analysis functionality. These tests verify that the autodiff compiler correctly analyzes and tracks type information for different Rust types during automatic differentiation.

## What These Tests Do

Each test compiles a simple Rust function with the `#[autodiff_reverse]` attribute and verifies that the compiler:

1. **Correctly identifies type information** in the generated LLVM IR
2. **Tracks type annotations** for variables and operations
3. **Preserves type context** through the autodiff transformation process

The tests capture the stdout from the autodiff compiler (which contains type analysis information) and verify it matches expected patterns using FileCheck.

Note: by default, run-make test's rustc() will try to cross-compile for targets tested under CI, which includes some Tier 2 targets that do not support std. You may wish to limit this further if you only wish to check this as a host test, e.g. //@ ignore-cross-compile.

I've not looked at the exact tests, but you may also wish to restrict which platforms these run-make tests run against. For instance, apple and windows Tier 1 targets? Or i686 msvc, etc.

Question: is the exact level of debuginfo important for these tests? If it is, consider explicitly spelling it out as debuginfo_level("2") with a comment, ignore this review comment otherwise.

Enzyme has a parser for debug info metadata. Enzyme should "translate" the debug info into "Enzyme Typetrees", which it will then use later for computing derivatives. In reality Enzyme's debug metadata parser was untested for too long and doesn't seem to do anything (based on the output of these tests). Still, I would hard-code the debug info level since it (in theory) could affect the test output.

Also, these tests are meant to capture the status-quo. In the second half Karan will generate TypeTrees directly from MIR, so it's good to have a before/after comparison with the test cases.

.run();

let stdout = output.stdout_utf8();
let stderr = output.stderr_utf8();

// Write the outputs to files
rfs::write("const_pointer.stdout", stdout);
rfs::write("const_pointer.stderr", stderr);

// Run FileCheck on the stdout using the check file
llvm_filecheck()
.patterns("const_pointer.check")
.stdin_buf(rfs::read("const_pointer.stdout"))
.run();
}
