ringabout e39272eaa8 fixes #25637; nim ic with destructors (#25723)
fixes #25637

This pull request refactors the way the `sfInjectDestructors` flag is
set on symbols during lambda lifting in the Nim compiler. The main
change is the introduction of a helper procedure to encapsulate the
logic for marking symbols that require destructor injection, improving
code clarity and maintainability.

Refactoring and code quality improvements:

* Introduced the `markInjectDestructors` procedure to encapsulate the
logic for marking a symbol with the `sfInjectDestructors` flag, ensuring
that `backendEnsureMutable` is always called before modifying the
symbol's flags.
* Replaced direct flag manipulation (`owner.incl sfInjectDestructors`
and `prc.incl sfInjectDestructors`) with calls to the new
`markInjectDestructors` procedure in multiple locations, including
`makeClosure`, `createTypeBoundOpsLL`, and `rawClosureCreation`.

This directory contains the test cases.

Each test must have a filename of the form: t*.nim

Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore top-level tests like tests/tbar.nim.

Specs

Each test can contain a spec in a discard """ ... """ block.

Check out the parseSpec procedure in the specs module for a full and reliable reference

action

Specifies what action this test should take.

Default: run

Options:

  • compile - compiles the module and fails the test if compilations fails.
  • run - compiles and runs the module, fails the test if compilation or execution of test code fails.
  • reject - compiles the module and fails the test if compilation succeeds.

There are certain spec keys that imply run, including output and outputsub.

Categories

Each folder under this directory represents a test category, which can be tested by running koch tests pcat <category> (or cat to avoid parallel testing, which is slower).

The folder dll contains simple DLL tests.

The folder realtimeGC contains a test for validating that the realtime GC can run properly without linking against the nimrtl.dll/so.
