Xtensa port maintainer

I am moving to a new job and will no longer be able to serve as the Xtensa port maintainer for GCC. I would like to nominate Sterling Augustine to take my place. Sterling has done a lot of work on the GNU assembler and recently worked on GCC with me to use DWARF unwinding for Xtensa. I think

Re: help regarding suif

Vivek, GCC and the GNU project have nothing to do with SUIF. If you want to ask questions about SUIF, you should do so on a more appropriate mailing list. I suggest you look here: http://www-suif.stanford.edu/mailman/listinfo/suif-talk/ Good luck. --Bob
