* fixes #4695; closure iterators support for JS backend (#23493)ringabout2024-04-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | fixes #4695 ref https://github.com/nim-lang/Nim/pull/15818 Since `nkState` is only for the main loop state labels and `nkGotoState` is used only for dispatching the `:state` (since https://github.com/nim-lang/Nim/pull/7770), it's feasible to rewrite the loop body into a single case-based dispatcher, which enables support for JS, VM backend. `nkState` Node is replaced by a label and Node pair and `nkGotoState` is only used for intermediary processing. Backends only need to implement `nkBreakState` and `closureIterSetupExc` to support closure iterators. pending https://github.com/nim-lang/Nim/pull/23484 <del> I also observed some performance boost for C backend in the release mode (not in the danger mode though, I suppose the old implementation is optimized into computed goto in the danger mode) </del> allPathsAsgnResult???

* fix atomicarc increment (#23427)Jaremy Creechley2024-03-251-1/+1
| | | | | | | | | | | | The fix to the atomicArc looks to use `-1` as the check value from the `SharedPtr` solution. However, it should be `-rcIncrement` since the refcount is bit shifted in ARC/ORC. I discovered this playing around doing atomic updates of refcounts in a user library. Related to https://github.com/nim-lang/Nim/issues/22711 @ringabout I believe you ported the sharedptr fix?

* Fix system.currentSourcePath() documentation [backport 2.0] (#23243)rockcavera2024-01-231-4/+5
| | | | | The documentation links for `parentDir()` and `getCurrentDir()` are broken as they are no longer part of `std/os`. Link changed to `std/private/ospaths2`.

* Deprecate asm stmt for js target (#23149)ASVIEST2024-01-022-85/+85
| | | | | | | | | | | | | | | | | | | | | | | why ? - We already have an emit that does the same thing - The name asm itself is a bit confusing, you might think it's an alias for asm.js or something else. - The asm keyword is used differently on different compiler targets (it makes it inexpressive). - Does anyone (other than some compiler libraries) use asm instead of emit ? If yes, it's a bit strange to use asm somewhere and emit somewhere. By making the asm keyword for js target deprecated, there would be even less use of the asm keyword for js target, reducing the amount of confusion. - New users might accidentally use a non-universal approach via the asm keyword instead of emit, and then when they learn about asm, try to figure out what the differences are. see https://forum.nim-lang.org/t/10821 --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>
* make `-d:debugHeapLinks` compile again (#23126)ringabout2023-12-241-4/+6
| | | | | I have made `realloc` absorb unused adjacent memory, which improves the performance. I'm investigating whether `deallocOsPages` can be used to improve memory comsumption.

* 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: 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.

| | | | | | | | | | | | `{.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.
