fixes #22639 A `tyGenericInst` has its last son as the instantiated body of the original generic type. However this type keeps its original `sym` field from the original generic types, which means the sym's type is uninstantiated. This causes problems in the implementation of `getType`, where it uses the `sym` fields of types to represent them in AST, the relevant example for the issue being [here](d13aab50cf/compiler/vmdeps.nim (L191)) called from [here](d13aab50cf/compiler/vmdeps.nim (L143)). To fix this, create a new symbol from the original symbol for the instantiated body during the creation of `tyGenericInst`s with the appropriate type. Normally `replaceTypeVarsS` would be used for this, but here it seems to cause some recursion issue (immediately gives an error like "cannot instantiate HSlice[T, U]"), so we directly set the symbol's type to the instantiated type. Avoiding recursion means we also cannot use `replaceTypeVarsN` for the symbol AST, and the symbol not having any AST crashes the implementation of `getType` again [here](d13aab50cf/compiler/vmdeps.nim (L167)), so the symbol AST is set to the original generic type AST for now which is what it was before anyway. Not sure about this because not sure why the recursion issue is happening, putting it at the end of the proc doesn't help either. Also not sure if the `cl.owner != nil and s.owner != cl.owner` condition from `replaceTypeVarsS` is relevant here. This might also break some code if it depended on the original generic type symbol being given.
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.
