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.
