During the instantiation of a generic type A, some other generic
type B may be instantiated multiple times with different parameters.
We can think about each instantiation as a function call that should
temporary bind the parameter names to concrete types. The problem
with the existing implementation in semtypinst was that it was
performing this binding within a shared global table. In this sense,
it was executing the code as a programming language featuring only
global variables. In such a language, re-entrant functions cannot be
defined properly and hence this was leading to problems with similar
types. The solution is simple - just like we need to introduce stack
frames to handle re-entrant functions, we introduce a stack of type
bindings that are pushed and popped during the generic instantiations.
This directory contains the test cases.
Each test must have a filename of the form: ``t*.nim``
Each test can contain a spec in a ``discard """"""`` block.
The folder ``rodfiles`` contains special tests that test incremental
compilation via symbol files.
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. It includes a C
client and platform specific build files for manual compilation.
