```nim
type
SysLockObj {.importc: "pthread_mutex_t", pure, final,
header: """#include <sys/types.h>
#include <pthread.h>""", byref.} = object
when defined(linux) and defined(amd64):
abi: array[40 div sizeof(clong), clong]
```
Before this PR, in refc, `resetLoc` generates field assignments for each
fields of `importc` object. But the field `abi` is not a genuine field,
which doesn't exits in the struct. We could use `zeroMem` to reset the
memory if not leave it alone
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.
