* catchable defects (#13626)Andreas Rumpf2020-03-121-1/+3
| | | | | | | | | | * allow defects to be caught even for --exceptions:goto (WIP) * implemented the new --panics:on|off switch; refs https://github.com/nim-lang/RFCs/issues/180 * new implementation for integer overflow checking * produce a warning if a user-defined exception type inherits from Exception directly * applied Timothee's suggestions; improved the documentation and replace the term 'checked runtime check' by 'panic' * fixes #13627 * don't inherit from Exception directly

* sink parameter inference for types that have destructors (#13544)Andreas Rumpf2020-03-041-2/+7
| | | | | | | | | | | | | | * ensure capitalize doesn't take an inferred sink parameter * sink parameter inference: first version, for now disabled. Changed that sink parameters can be consumed multiple times in order to adhere to our spec. * sink inference can now be disabled with .nosinks; sometimes for proc type interop this is required * fixes yet another critical DFA bug * better implementation that also understands if expressions etc * document sink parameter inference and allow for global disabling
* Remove dead magics (#13551)Arne Döring2020-03-031-18/+16

* VM: support importc var, ptr/pointer types, cast int <=> ptr/pointer (#12877)Timothee Cour2020-01-051-1/+6
| | | | | | | | | | | | | | * VM: allow certain hardcoded special var variables at CT * VM: allow all importc var, cast[int](ptr) * fix tests tests/vm/tstaticprintseq.nim, tests/cpp/t8241.nim * VM: == works for ptr/pointer nodes * bugfix: ==, cast now also works for pointer, not just ptr * VM supports cast PtrLikeKinds <=> PtrLikeKinds / int * improve cname handling * fixup + bug fix * VM: support cast from ref to int * address comment: opcLdGlobalDeref => opcLdGlobalDerefFFI * defensive check against typ == nil
* --exception:goto switch for deterministic exception handling (#12977)Andreas Rumpf2020-01-011-4/+7
| | | | | This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior. Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.

* ARC: cycle detector (#12823)Andreas Rumpf2019-12-171-3/+7
| | | | | | | | | | | | | * first implementation of the =trace and =dispose hooks for the cycle collector * a cycle collector for ARC: progress * manual: the .acyclic pragma is a thing once again * gcbench: adaptations for --gc:arc * enable valgrind tests for the strutils tests * testament: better valgrind support * ARC refactoring: growable jumpstacks * ARC cycle detector: non-recursive algorithm * moved and renamed core/ files back to system/ * refactoring: --gc:arc vs --gc:orc since 'orc' is even more experimental and we want to ship --gc:arc soonish
