This is supposedly resolved ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65779#c16 ) in https://gcc.gnu.org/viewcvs?rev=232558&root=gcc&view=rev and included in the latest GCC 6 20160124 snapshot (at r232780).
I didn't seem to run into the issue building tests for powerpc/psim powerpc/mvme3100 pre-patch though, so can't currently confirm it's sorted. Patch attached to update the 4.12 RSB build set to this GCC snapshot. On Wed, 2016-01-20 at 07:49 +0100, Sebastian Huber wrote: > Yes, this bug is still a problem for several PowerPC BSPs.
