ayazhafiz 8c0e39211d Instantiate recursive aliases to their smallest closures Now, when we have two aliases like ``` T a : [ A, B (U a) ] U a : [ C, D (T a) ] ``` during the first pass, we simply canonicalize them but add neither to the scope. This means that `T` will not be instantiated in the definition of `U`. Only in the second pass, during correction, do we instantiate both aliases independently: ``` T a : [ A, B [ C, D (T a) ] ] U a : [ C, D [ A, B (U a) ] ] ``` and now we can mark each recursive, individually: ``` T a : [ A, B [ C, D <rec1> ] ] as <rec1> U a : [ C, D [ A, B <rec2> ] ] as <rec2> ``` This means that the surface types shown to users might be a bit larger, but it has the benefit that everything needed to understand a layout of a type in later passes is stored on the type directly, and we don't need to keep alias mappings. Since we sort by connected components, this should be complete. Closes #2458		2022-02-11 08:43:33 -05:00

Running our CodeGen tests

Our code generation tests are all in this crate. Feature flags are used to run the tests with a specific backend. For convenience, some aliases are added in .cargo/config:

[alias]
test-gen-llvm = "test -p test_gen"
test-gen-dev = "test -p test_gen --no-default-features --features gen-dev"
test-gen-wasm = "test -p test_gen --no-default-features --features gen-wasm"

So we can run:

cargo test-gen-llvm

To run the gen tests with the LLVM backend. To filter tests, append a filter like so:

> cargo test-gen-wasm wasm_str::small
    Finished test [unoptimized + debuginfo] target(s) in 0.13s
     Running src/tests.rs (target/debug/deps/test_gen-b4ad63a9dd50f050)

test wasm_str::small_str_literal ... ok
