| | | | | | | | | | | | | | | | | | | | | | | | new strictions on methods (#22991) **TODO** - [x] fixes changelog With the new option `nimPreviewVtables`, `methods` are confined in the same module where the type of the first parameter is defined - [x] make it opt in after CI checks its feasibility ## In the following-up PRs - [ ] in the following PRs, refactor code into a more efficient one - [ ] cpp needs special treatments since it cannot embed array in light of the preceding limits: ref https://github.com/nim-lang/Nim/pull/20977#discussion_r1035528927; we can support cpp backends with vtable implementations later on the comprise that uses indirect vtable access --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>
* reserve `sysFatal` for `Defect` (#22158)Jacek Sieka2023-11-062-8/+8
| | | | | | | | Per manual, `panics:on` affects _only_ `Defect`:s - thus `sysFatal` should not redirect any other exceptions. Also, when `sysFatal` is used in `nimPanics` mode, it should use regular exception handling pipeline to ensure exception hooks are called consistently for all raised defects.

* NIR: progress (#22817)Andreas Rumpf2023-10-121-0/+3
| | | | | | Done: - [x] Implement conversions to openArray/varargs. - [x] Implement index/range checking.
* NIR: Nim intermediate representation (#22777)Andreas Rumpf2023-10-115-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* items, pairs and friends now use `unCheckedInc` (#22729)ringabout2023-09-201-26/+31
| | | | | | | | | | | | `{.push overflowChecks: off.}` works in backends. Though it could be implemented as a magic function. By inspecting the generated C code, the overflow check is eliminated in the debug or release mode. ![image](https://github.com/nim-lang/Nim/assets/43030857/49c3dbf4-675e-414a-b972-b91cf218c9f8) Likewise, the index checking is probably not needed.
