PPCG 0.05 was released containing various changes:
-
Fix live-out computation
Due to a bug, the live-out computation would consider all elements written by a write to have been killed as soon as one of those elements had effectively been killed. This could in rare cases result in some statement instances mistakenly getting removed during dead code elimination.
-
Optionally compute schedule for C target
The original support for the C target only added the basic infrastructure and did not even allow the input code to be rescheduled. Now, this backend will also (optionally) reschedule the code, but support for this target is still fairly basic.
-
Create single kernel for non-permutable subtree
If some parts of the code that is mapped to the device do not have any parallelism, then a kernel would be launched for each instance of that part of the code, even if that would result in loop on the host that only launches such kernels. Now, a single kernel is invoked for the entire non-parallel part.
