[Jiakai Xu]

Hi Paul,

I am very sorry for the delayed response. Due to an issue with my email 
client, I did not receive your previous message.

I have just submitted the v2 patch which incorporates the suggestions from 
the LLVM folks. Please review it at your convenience.

Again, I apologize for the delay and any inconvenience this may have caused.

Best regards,
Jiakai
