Dear Calc developers,

It seems that OpenCL on the Apple silicon version of libreoffice calc could not be enabled even after confirming and restarting the program after selecting OpenCL in the preferences. Could you please have a look?

Meanwhile, I may offer some help on this issue if someone can kindly point the direction. It looked like it either does not support OpenCL 1.2 (Apple deprecated version) or could not load/find the libopencl.so. The former made me skeptical for I could enable calc's OpenCL in an Intel xe GPU.

By the way, thank you for your loads of supports coming in https://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=OpenCL owing to Luboš Luňák and others. The median was deleted due to lacking a sort algorithm, which may need someone to fix for GPU-based bitonic sort is a good candidate.  

Thank you very much!

Best wishes,
Jinchuan Tang
