* reserve `sysFatal` for `Defect` (#22158)Jacek Sieka2023-11-061-1/+1
| | | | | | | | 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.
* fixes #22898; fix #22883 differently (#22900)ringabout2023-11-051-4/+0
| | | | | | fixes #22898 In these cases, the tables/sets are clears or elements are deleted from them. It's reasonable to suppress warnings because the value is not accessed anymore, which means it's safe to ignore the warnings.

* fixes #22856; enables `-d:nimStrictDelete` (#22858)ringabout2023-10-241-5/+1
| | | | | | | | fixes #22856 `-d:nimStrictDelete` is introduced in 1.6.0, which promised to be enabled in the coming versions. To keep backwards incompatibilities, it also extends the feature of `-d:nimAuditDelete`, which now mimics the old behaviors.

* NIR: Nim intermediate representation (#22777)Andreas Rumpf2023-10-111-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
