OpenCL

Common issues

• printf in OpenCL: still broken as of Clang 20.1
• C++20 support:
  • No one actively working on it
  • But also not opposed to it
  • If we want to it, we would have to do it ourselves (post contains some pointers to start)
• PoCL improved error on recursion: merged

ZS Decoder

Two issues:

• Corruption in padding region by kernel
• Kernel marks a single charge as invalid

-> Seems to be somehow related to shared memory:

• zeroing shared memory at kernel start fixes invalid charge position but still outputs charge in wrong pad
• Doesn't fix padding corruption

Currently working on standalone reproducer for decoder kernel
