Replace obsolete -mattr=n64 command line option with -target-abi=n64. No functional changes. llvm-svn: 230628 2015-02-26 20:29:48 +08:00			`; RUN: llc < %s -march=mips64el -mcpu=mips4 -target-abi=n64 \| FileCheck %s`

Add code in MipsDAGToDAGISel for selecting constant +0.0. MIPS64 can generate constant +0.0 with a single DMTC1 instruction. llvm-svn: 146999 2011-12-21 06:25:50 +08:00
