From ee92c0fe5c1b9d59508273916e2c9a75b68dbc13 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Thu, 21 Apr 2016 01:25:29 +0200 Subject: nds32: add support for new architecture Add support for Andes Technology NDS32 architecture. See here http://www.andestech.com/en/index/index.htm for more informaton. Verification of the port from an older uClibc port was done on a sponsored AG101p board. The testsuite only has 5 errors, three are related to an existing bug in dlclose() with LT.old, also happening on cris32 and m68k. Failures to fallocate/posix_fallocate are unresolved. Thanks to Andes Technology sponsoring the hardware and being very helpful while doing the uClibc-ng porting.
