From 8d0168264a689ab82b55887132a4db0081a24f93 Mon Sep 17 00:00:00 2001 From: Uroš Bizjak Date: Thu, 24 Jan 2019 10:22:55 -0800 Subject: alpha: Fix __remqu corrupting $f3 register There was missing restore of $f3 before the return from the function via the $y_is_neg path. This caused the math/big testcase from Go-1.11 testsuite (that includes lots of corner cases that exercise remqu) FAIL.
