// summary: - this is the final up date for MTevaluator Virtual machine for Summer 2002
//	    - stackmem_LRU bug fixed
//	    - renamed header files for easier access.. commented in vm.cpp
//	    - this version is tested for Linux rename vm.cpp to vm.cc to run in lunux,
//	      add linux path to all change all the neccessary headers declaired in the begining of the file
//

//            then change the file name for MS

// summery: - MTSRA for stack is working. see stackmem3.h

//			-PL LRU for heap is working see heapmem2.h

//			- added LRUTS to PageTableEntry in MTdeclaration.h to support LRU time stamp

//			-PL updated new code space stuff DLLLRUcodeinfo.h, FIFOcodeinfo.h, LRUcodeinfo.h

//				* Ok, here are the 3 versions of Code space. Simply change the #include

//				  "codeinfo.h" to the file you wish to use. To use the data collection stuff

//				  about how many faults and other cool info add code->getinfo(); to

//				  the end of MTmachine::run() function.

// summery: - number() and symbol() could now return false to flag, and return true to vm;

//			- MTconstant.h	SETCONT op_code to 400, SCONT op_code to 510

//			- function add_instr() opcode range increased to 400

//			- added primitive to RestoreFlag to Flag register

//			- heapmem.h error message correction : heap page -> heap space

//			- primitives atom(), nil() now return true

//			- primitive eq() error message correction

//			- primitive numEQ() now support REALTAG

//			- added Function ArgPop to help poping in Primitives

//			- all the POPing in primitives are done by ArgPop()

// by KF, all changes commented..

// summery: - changed logic buggies related to the flag register in Boolean ops, Relational ops, 

//			  FL relational, Flow control.

//			- added primitive to SaveFlag to stack

//			- change lable addresses used in random list to actual lable names

//			- change all stackmem to stackmem2 to run LRU

//			- change all heapmem to heapmem2 to run LRU

//			- change all stack mem to stackmem to run marco's LRU (doesn't work :P )

// problems: * unable to change label address (195) to labelname "DONELABEL"

//			 * unable to change label address (731) to labelname "mkListAccum"

//			 * for primitive number() and symbol(), should be able to return false to flag, 

//			   and true to VM
