test(es/minifier): Enable more terser tests (#7396) 2023-05-16 03:21:08 +00:00

fix(es/renamer): Ensure that param and function body are in same scope (#7271) 
**Description:**

The problem arises in L235 of swc_ecma_transforms_base/src/rename/mod.rs

```rs
unit!(visit_mut_fn_decl, FnDecl, true);
```

which calls `get_map` and evals to

```rs
node.visit_children_with(&mut v);
```

with `FnDecl` and `Analyzer` in L132. However, in `Analyzer`, a visit to raw function was not overloaded, so function arguments and function body are considered different scopes.

**Related issue:**

 - Closes #7261.

feat(es/minifier): Clone trivial literals in sequential inliner (#6005) 
**Description:**

As our minifier is two-pass by default, this is enough.

At the first pass, we inline all numeric literals using sequential inliner, and minifier can then inline constants correctly in the second pass.
