[PATCH 3/3] ppc: Add endianness check to _truncr_d_i


From: Kimplul
Subject: [PATCH 3/3] ppc: Add endianness check to _truncr_d_i
Date: Thu, 18 Nov 2021 14:53:41 +0200

When running on ppc64el, _trunc_d_i loads the upper four bytes of the truncated
value instead of the lower bytes, causing make check to fail.
