From 8275f3d9467018175f553994523e0d2b14f368df Mon Sep 17 00:00:00 2001 From: Kevin Petit Date: Wed, 17 Jul 2024 12:21:28 +0100 Subject: [PATCH] Generate OpenCL C feature dictionary Features are stored in a text file for now. Ultimately, we probably want to use the XML registry for this. Generation script taken from #1174 with a few modifications. Contributes to #1166.
