Turning off DIAGNOSTIC will, however, make your machine run a lot
faster. (Once upon a time, DIAGNOSTIC was supposed to be cheap and
only DEBUG was expensive; however, that's no longer true.)
at least on sparc64 DIAGNOSTIC causes only a few percent of performance
loss. the worst case i found -- ./configure -- averaged at 7% loss,
but most things were 1-3%.
you could probably avoid this assert by disabling i915drm as well. this
also looks like it might be the same problem as in PR/42980, but with
a different caller.
