MIPS: should -funwind-tables option be made default one on MIPS

[Manjunath Matti]

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.
