* rework `wasMoved`, `move` on the JS backend (#23577)ringabout2024-05-081-9/+0
| | | | | `reset`, `wasMoved` and `move` doesn't support primitive types, which generate `null` for these types. It is now produce `x = default(...)` in the backend. Ideally it should be done by ast2ir in the future

| | | | | | | | | fixes #23422 ref https://github.com/nim-lang/Nim/issues/20997 https://github.com/nim-lang/Nim/pull/21165 The function `cardSet` is used for large sets that are stored in the form of arrays. It shouldn't be passed as a pointer

* fixes #22597; avoid side effects for call returning openArray types (#23257)ringabout2024-01-261-4/+11
| | | | | | | | | | | | | | fixes #22597 ```nim proc autoToOpenArray*[T](s: Slice[T]): openArray[T] = echo "here twice" result = toOpenArray(s.p, s.first, s.last) ``` For functions returning openarray types, `fixupCall` creates a temporary variable to store the return value: `let tmp = autoToOpenArray()`. But `genOpenArrayConv` cannot handle openarray assignements with side effects. It should have stored the right part of the assignment first instead of calling the right part twice.

* NIR: progress (#22817)Andreas Rumpf2023-10-121-3/+0
| | | | | | Done: - [x] Implement conversions to openArray/varargs. - [x] Implement index/range checking.
* NIR: Nim intermediate representation (#22777)Andreas Rumpf2023-10-111-33/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Theoretical Benefits / Plans: - Typed assembler-like language. - Allows for a CPS transformation. - Can replace the existing C backend by a new C backend. - Can replace the VM. - Can do more effective "not nil" checking and static array bounds checking. - Can be used instead of the DFA. - Easily translatable to LLVM. - Reasonably easy to produce native code from. - Tiny memory consumption. No pointers, no cry. **In very early stages of development.** Todo: - [x] Map Nim types to IR types. - [ ] Map Nim AST to IR instructions: - [x] Map bitsets to bitops. - [ ] Implement string cases. - [ ] Implement range and index checks. - [x] Implement `default(T)` builtin. - [x] Implement multi string concat. - [ ] Write some analysis passes. - [ ] Write a backend. - [x] Integrate into the compilation pipeline.
