Well, e.g. at the start GCC 5 and later support two offloading configurations: OpenMP to Intel MIC targets (upcoming Intel Xeon Phi products codenamed KNL) as well as MIC emulation on host. should be kept, and in the GCC 13 entry say that the support has been removed. Or perhaps better split the GCC 5 entry to say that GCC 5 and later support OpenACC to NVidia PTX and another entry that GCC 5 to GCC 12 support OpenMP to Intel MIC. As there is just one wiki for all the GCC versions, I think we should keep the MIC stuff in there for now but add notes to the various spots that it isn't there for GCC 13 anymore (repeat the info). And when GCC 12.5 is released and branch 12 closes we can drop it except from the first part of the wiki. Jakub
