I finish analysing for it, it is really only one issue for gcc5, and I
guess, this issue is also not only for xtensa. I send related fix patch
to gcc patch mailing list, hope it can pass checking.
The cause is "the variables are not initialized before using them", the
bug information is "https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65117".
After fix this issue, it can build xtensa Linux kernel with allmodconfig
Open, share, and attitude like air, water, and life which God blessed
