From d0649b2d8efca33363e399f1ba07d77e85901cfc Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 10 Aug 2015 15:25:10 +0000 Subject: Fix ldbl-128ibm sinhl inaccuracy near 0 (bug 18789). ldbl-128ibm sinhl uses a too-big threshold to decide when to return the argument, resulting in large errors. This patch fixes it to use a more appropriate threshold. Tested for x86_64, x86 and powerpc.
