Donny/강동윤	581aafb4df	perf(visit): Introduce Pass API and adjust visitor APIs for it (#9680) ... **Description:** - `Pass`: `FnMut(&mut Program)`. **Breaking Changes:** - `chain!`: Use a tuple instead. You can replace all `chain!(` with `(` with IDE feature and it will work. - `chain!` with 13 or more args: Use nested tuples for items after 13th element. **Related issue:** - Related to https://github.com/swc-project/swc/issues/9601	2024-10-29 11:25:16 +09:00

CPunisher	7344a638b5	feat(es/minifier): Optimize switch with side effect and termination tests (#9677) ... **Description:** This is learnt from https://github.com/terser/terser/pull/1044 **Key point:** all the cases (statements) after the last side-effect and non-terminated one are useless. There are also some points on whether a statement is side-effect free: - **Var declaration:** I think var declaration always contains side effect. - **Function declaration:** In non-strict mode, function declaration is same as var declaration. In strict mode, function is declared in enclosing block scope, so it's side-effect free. But there is a bad case when we call the function before it is declared in the switch case: ```js "use strict"; const k = (() => { let x = 1; switch (x) { case y(): case x: { async function y() { console.log(123); } } } return x; })(); ``` **This is an existing bug.** I'm not sure whether we should fix it since it is a very bad code and I also find some similar bad cases with terser. ~I'm also not sure it's appropriate to introduce context variable `in_strict` for `StmtExt:: may_have_side_effects`, because `in_strict` could change from `false` to `true`. But this is a **conservative** mistake and does not break the program. Maybe we should use visitor for context-aware side effect checker in the future.~ **Related issue:** - Closes https://github.com/swc-project/swc/issues/8953	2024-10-29 10:39:05 +09:00

Levi	88a2186ba4	feat(es/minifier): Support unary negate in cast_to_number (#9642) ... **Description:** Adds support for `-` in `cast_to_number`. Before it only worked if `arg` is `Infinity`. Now it uses a recursive call on `arg` so it works for expressions like `-5`, `-[]` etc. This change is important because negative number literals (e.g. `-5`) are a `UnaryExpr` with `op`=`-` & `arg`=`5`, unless you apply `expr_simplifier` pass or something else that uses it.	2024-10-15 08:00:39 +09:00
CPunisher	4436621564	fix(es/minifier): Check type of assignment target before merging assignments (#9617) ... **Description:** Collect types of vars, maybe other optimization could benefit from this: `merged_var_type: Option<Value<Type>>` When the variable is reassigned, the we merge the types with some simple rules: `None` + `None` = `None` `None` + `Some(ty)` = `Some(ty)` `Some(ty1)` + `Some(ty2)` if `ty1` == `ty2` = `Some(ty1)` Otherwise = Unknown **Related issue:** - Closes https://github.com/swc-project/swc/issues/8718	2024-10-14 09:55:53 +09:00

A new API in swc_ecma_utils has been added, `to_js_int32` and `to_js_uint32` that allows external callers to convert `f64`s to `i32` and `u32` so they can perform bitwise operations themselves if they're trying to replicate JavaScript behaviour. I also believe the updated bit shifting logic should be accessible externally via swc_ecma_utils, but unsure about this. **Related issue:** - Closes https://github.com/swc-project/swc/issues/9256 --------- Co-authored-by: magic-akari <akari.ccino@gmail.com>	2024-07-16 18:56:05 +09:00

Levi	2aef14d34d	feat(es/utils): Support for arrays using cast_to_number (#9212) ... **Description:** This PR allows `ArrayLit`s to be converted to numbers in the `cast_to_number` function. This allows expressions using arrays to be converted to numbers. See some example expressions below that were previously not able to be computed, but are now able to due to this change. ```js +[] // 0 +[[]] // 0 +[1] // 1 +[undefined] // 0 +[null] // 0 +[[1]] // 1 +[,] // 0 +[,,] // NaN ``` Regarding the implementation, arrays are converted to strings, and the string is then parsed as a number. So arrays like `[]` and `[undefined]` return `""` which then return `0` when parsed as a string. This is also why arrays with more than one element can't be parsed because e.g. `[1, 2]` returns `"1,2"`. This procedure follows the ECMAScript specification. https://262.ecma-international.org/6.0/#sec-tonumber https://262.ecma-international.org/6.0/#sec-toprimitive	2024-07-12 12:15:12 +09:00
