2006-05-14Made EM_SPARC32PLUS be recognized as belonging to the SPARC architecture. ↵Gabe Black
Programs which have this set will not work because the stack works differently, so this should probably throw an error and quit. --HG-- extra : convert_revision : b770045cad02d30445de0d7cc4d8c611a0ac931f

2006-05-11First pass at a serializer object, may need to work on naming of object and ↵Ron Dreslinski
functions: Intended Use: A SimObject will call the serializer when it needs the state to be serializable (i.e. switchCPUs, checkpoint, switch memory access model). It will call the requestSeialization() function. The Serializer will signal all the objects in its list to drain their state via the SimObject method drain(). Drain() has a default implementation to just signal done. When each object is drained it will signal the Serializer that it has drained via the signalDrained() function. The Serializer will collect these signals, when all have drained it will signal the initial requestor via serializationComplete() method in the SimObject. Once that object is done, it will signal the Serializer to resumeExecution(). The Serializer will signal all the objects in its list to resume via the resume() method on the SimObject. SConscript: Add serializer object to build list sim/sim_object.cc: Add default behavior for drain (just signal finished, must be overided if you really must drain something) sim/sim_object.hh: Add functions for serializer --HG-- extra : convert_revision : 15aa2d1b42010c2d703bef9114c11d079c216170

Auxiliary Functions and Formats for FP in general arch/mips/isa/decoder.isa: ISA Parser doesnt accept operands of different types in one instruction so fix this for unorderedFP functions...

The PS instructions allow SIMD in a pipeline... arch/mips/isa/formats/fp.isa: Add some more Formats for FP operation. I will add some auxiliary code through these formats to alleviate code redundancy in the decoder.isa arch/mips/isa/operands.isa: Add operands for Paired Singles Ops arch/mips/isa_traits.cc: removed convert&round function and replace with fpConvert.

There still needs to be a work around to handle the paired singles operations ... arch/mips/isa/decoder.isa: More revamping of the floating point ops in decoder.isa. Change all of the "convert and round" functions to fpConvert. Also, the utility functions roundFP, truncFP, and unorderedFP are in place everywhere.
