Hi, In glibc the following commit adds support for backtrace in MIPS port. commit 04d450263622ae7c37cb841f93b3bcf4e9397a88 Link: http://repo.or.cz/w/glibc-ports.git/commit/04d450263622ae7c37cb841f93b3bcf4e9397a88 But during compilations of any program the user needs to provide/pass -funwind-tables to GCC, to be able to do a backtrace. I am proposing why not the option be made the default one! it would be useful to all. Please let me know if its ok, I have a patch which will enable -funwind-tables as a default option. Regards, Manjunath S Matti.
