believe there is a chicken-and-egg situation here - few people use gcc
with these devices because there is poorer device support compared to
Freescale CodeWarrior or Green Hills, and there is little incentive for
gcc developers (such as the CodeSourcery or IBM PPC folks) to support
devices in gcc if no one uses that combination.
Yes, we use GCC also one these chips, however, due to the lack of VLE
support the situation is even worse. Looks like support for the non-IBM
PowerPC is dead in GCC. I can understand this pretty well.
It's not true though; we still support all those cores, just not the
VLE extension (we never have), and I propose GCC 7 will drop the SPE
extension as well -- not all other support we have for those cores.
They will have to use soft float, alas.
Will the SPFP APU still be supported?
Kind regards,
Patrick
