From e428bff6b2825a5081ae2f081471e5e3921a2e9f Mon Sep 17 00:00:00 2001 From: Austin Foxley Date: Thu, 18 Nov 2010 10:20:43 -0800 Subject: Adding quad float gcc intrinsic implementation for SPARC Sparc-Gcc generates q_xxx intrinsic calls for quad float ("long double") code. The routines from glibc's glibc-2.9/sysdeps/sparc/sparc32/soft-fp/* where taken and ported to uclibc.
