Hi All, Embarrassingly, due to personal reasons, I may not be able to complete the series of patches on the forward side of GCC CFI for the time being. Please forgive me for not realizing that I should have sent this help email a long time ago :( This topic has been delayed for a long time, and I would be very grateful if someone can help complete this series of patches. BTW, please let me know if there are more groups I can cc for help. Thanks! Dan.
