GCC 8 PowerPC Argument Changes

[dufault at hda.com]

I should be following the status of the SPE support but haven’t, it’s an important platform for one of my clients.  A little googling doesn’t make it clear how well the support is moving in to GCC 8, I only found again that it would be a new target.  Hopefully someone following GCC on the list has been paying attention to this and knows whether or not it’s really being supported.
