From 673c426bfbe58ee626d346b13365b73712f961ba Mon Sep 17 00:00:00 2001 From: Steve Ellcey Date: Wed, 28 Jan 2015 14:56:07 -0800 Subject: Update MIPS configuration rules. Add a configuration choice for the NaN format on MIPS (either the standard (legacy) format or the newer IEEE 2008 format. Change how CPU_LDFLAGS are set for MIPS. Use the same value as CPU_CFLAGS since CC is used to do linking. This ensures consistency between compiles and links and adds support for N32 ABI to linking.
