From f5d840a079d18b3efad7938070b964f82e9bbcaf Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Wed, 13 May 2015 22:19:59 +0200 Subject: [PATCH] bn/asm/vis3-mont.pl: fix intermittent EC failures on SPARC T3. BLKINIT optimization worked on T4, but for some reason appears "too aggressive" for T3 triggering intermiitent EC failures. It's not clear why only EC is affected...
