echuraev opened a new pull request #7714:
URL: https://github.com/apache/tvm/pull/7714
1. In case when we build runtime without ARC, we can have problems with
memory releasing. Due to some of Objective-C methods returns
autoreleased pointers, we should specify `autoreleasepool` blocks to
determine life cycle of these pointers.
2. Added fix for problem with work group size.
Sometimes auto scheduler generates parameters when work group size
is more than possible. And in this case we got assert from Metal
library. Added check for this situation and it helps to avoid
assert.
3. Fixed memory leak problem when fill tensor by random data.
DLManagedTensor increases reference counter in NDArray but nobody
delete this DLManagedTensor in proper way. This is why memory which
was allocated by NDArray was never released.
4. Removed unnecessary retains. It is not necessary to use retain in some
places where they were used, due to we build metal runtime without
ARC.
