add pseduo instruction support for sparc
util/m5/Makefile.alpha: Clean up to make it a bit easier to muck with util/m5/Makefile.alpha: Make the makefile more reasonable util/m5/Makefile.alpha: Remove authors from copyright. util/m5/Makefile.alpha: Updated Authors from bk prs info util/m5/Makefile.alpha: bk cp Makefile Makefile.alpha src/arch/sparc/tlb.cc: Clean up the cache code a little bit and make sure the uncacbale bit is set when appropriate src/arch/alpha/isa/decoder.isa: src/sim/pseudo_inst.cc: src/sim/pseudo_inst.hh: Rename AlphaPseudo -> PseudoInst since it's all generic src/arch/sparc/isa/bitfields.isa: src/arch/sparc/isa/decoder.isa: src/arch/sparc/isa/includes.isa: src/arch/sparc/isa/operands.isa: Add support for pseudo instructions in sparc util/m5/Makefile.alpha: util/m5/Makefile.sparc: split off alpha make file and sparc make file for m5 app util/m5/m5.c: ivle and ivlb aren't used anymore util/m5/m5op.h: stdint seems like a more generic better fit here util/m5/m5op_alpha.S: move the op ids into their own header file since we can share them between sparc and alpha --HG-- rename : util/m5/Makefile => util/m5/Makefile.sparc rename : util/m5/m5op.S => util/m5/m5op_alpha.S extra : convert_revision : 490ba2e8b8bc6e28bfc009cedec6b686b28e7834
