Subject: [PATCH 1/9] nds32: lib: To use generic lib instead of libgcc to prevent the symbol undefined issue.
Date: Thu, 19 Apr 2018 21:18:07 +0800	[thread overview]
Message-ID: <347705ade75b5901537034561fd67311b1260358.1524143428.git.greentime@andestech.com> (raw)

We can use the generic lib to fix these error because the symbol of
libgcc in toolchain is not exported.

ERROR: "__ucmpdi2" [fs/xfs/xfs.ko] undefined!
ERROR: "__ashrdi3" [fs/xfs/xfs.ko] undefined!
ERROR: "__lshrdi3" [fs/xfs/xfs.ko] undefined!
ERROR: "__ashldi3" [fs/ntfs/ntfs.ko] undefined!
...
