--- Comment #8 from William J. Schmidt <wschmidt at gcc dot gnu.org> 2012-04-06 19:08:09 UTC --- Roberto, I tried your patch, but got the following error: PPL error code -8 PPL C interface error: ppl_set_deterministic_timeout: the PPL Watchdog library is not enabled. I assume this is a configuration feature for PPL that GCC doesn't enable. I wonder if there are portability concerns here. Graphite maintainers, can you please comment? I'm afraid I know practically nothing about Graphite.
