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
David Sherret	2bbd1e8485	feat(es/parser): Ability to get script's potential module errors (#9682) ... **Description:** In Deno I'm now parsing stuff as a program more often because I sometimes now need to discover if something is a script or es module by looking at the contents. A problem is that the module errors are discarded when parsing as a script, but I still might need them later if I discover the program the program should be treated as an ES module. **BREAKING CHANGE:** Adds a new method to the `Tokens` trait.	2024-10-29 09:50:14 +09:00

CPunisher	aec0e402d8	chore(ci): Remove miri ci for swc_ecma_codegen and swc_ecma_minifier (#9664) ... **Description:** Running miri for `swc_ecma_codegen` and `swc_ecma_minifier` is too slow. Miri on `swc_ecma_codegen` consumes up to 4 hours, and miri on `swc_ecma_minifier` consumes up to 6 hours, which exceeded github's 6 hour limit and makes ci bound to error. Since they do not introduce too much unsafe code, I think we'd better remove the miri tests for them or run partial tests in a reasonable time.	2024-10-22 14:03:20 +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
