Hey guys,
Any thoughts on this change?
Thinking about this some more we should probably rework the compat code
also and only do the check for link status if there is an assembly
shader right?
I wanted to hear from others first since for me it feels this change
seems specific to separate shader programs (I had a patch on list that
skipped the check for those programs that were not in use by current
pipeline).
The reason is that with regular programs I can't see a way to continue
if relinking fails (because program is now in bad state). I think user
should detach the malfunctioning stage and link again. However with SSO
relink to a unused stage may fail but we can still have a complete
working program with stages marked as used.
Thanks,
Tim
