binutils-gdb/binutils/testsuite/binutils-all/group-5.d
Nick Clifton fbaf61ad52 Andes Technology has good news for you, we plan to update the nds32 port of binutils on upstream! 
We have not only removed all unsupported and obsolete code, but also supported lost of new features,
including better link-time relaxations and TLS implementations. Besides, the files generated by the
newly assembler and linker usually get higher performance and more optimized code size.
