* nvro don't touch cdecl types [backport: 1.6] (#19461)flywind2022-01-281-3/+3
| | | * nvro don't touch cdecl types; fix #19342 again
* allow converting static vars to `openArray` (#19035)Etan Kissling2021-10-221-1/+1
| | | | | | | | | | | When assigning constant output to a seq, and then passing that static seq to other functions that take `openArray`, the compiler may end up producing errors, as it does not know how to convert `static[seq[T]]` to `openArray[T]`. By ignoring the `static` wrapper on the type for the purpose of determining data memory location and length, this gets resolved cleanly. Unfortunately, it is relatively tricky to come up with a minimal example, as there are followup problems from the failing conversion, e.g., this may lead to `internal error: inconsistent environment type`, instead of the relevant `openArrayLoc` error message.

* --exception:goto switch for deterministic exception handling (#12977)Andreas Rumpf2020-01-011-0/+4
| | | | | 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.
