From 7fa0ddc1d63806769d1b6246a62708d3bde39037 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 7 May 2019 10:48:11 +1000 Subject: [PATCH] target/ppc: Fix vsum2sws A recent cleanup changed the pre zeroing of the result from 64 bit to 32 bit operations: - result.u64[i] = 0; + result.VsrW(i) = 0; This corrupts the result.
