I am looking for options to bring it back to GCC 15 NXP did not have the financial motivation nor the will to maintain the port. NXP was free-riding on the IBM team. Without analysis, it's difficult to estimate the amount of work. A lot of things in GCC between GCC 8 and GCC 15 -- both in the common parts of the compiler and in the PowerPC port from which PowerPC SPE was split.
