From 3d8b06bc6108aa20a6591f52e7d9cbbd63c20e0a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 6 Jun 2016 22:21:11 +0000 Subject: Fix dbl-64 asin (sNaN) (bug 20213). The dbl-64 version of asin returns sNaN for sNaN arguments. This patch fixes it to add NaN arguments to themselves so that qNaN is returned in this case. Tested for x86_64 and x86.
