However, the architecture itself will exist through at least 2025, as chips are guaranteed to be produced until at least that time (part of Freescale/NXP's longevity program). Also, I have some patches in review adding SPE support to LLVM, and will likely be committing them in the next month after I get final reviews and rebase. I'm hoping powerpc support gets enhanced to the point of full support before too long, so we can switch powerpc* targets entirely to clang/llvm. However, we need compiler people who could invest time into doing the work. - Justinhelp
