From 66fcf8ffcfb538dda612bfa57d28d502e83ff795 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sun, 15 May 2011 14:09:18 +0200 Subject: [PATCH] target-i386: use floatx80 constants in helper_fld*_ST0() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of using a table which doesn't correspond to anything from physical in the CPU, use directly the constants in helper_fld*_ST0().
