ringabout 94008531c1 fixes #25457; make rawAlloc support alignment (#25476)
fixes https://github.com/nim-lang/Nim/issues/25457

Small chunks allocate memory in fixed-size cells. Each cell is
positioned at exact multiples of the cell size from the chunk's data
start, which makes it much harder to support alignment

```nim
sysAssert c.size == size, "rawAlloc 6"
if c.freeList == nil:
  sysAssert(c.acc.int + smallChunkOverhead() + size <= SmallChunkSize,
            "rawAlloc 7")
  result = cast[pointer](cast[int](addr(c.data)) +% c.acc.int)
  inc(c.acc, size)
```

While using big trunk, each allocation gets its own chunk

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.
