From dc29a7c8ae55ab1a267add8b4fe8daa35349b5c2 Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Mon, 29 May 2006 16:53:47 -0400 Subject: [PATCH] split off fullsystem and se iprs into two functions to remove lots of #ifs setup all initialization stuff for UA2005 Setup fullsys build options Start to make fullsystem compile src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: RCS to BitKeeper src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: Add support for doing virtual to physical translation using the in-memory page table src/arch/sparc/vtophys.cc: a tad bit of error checking src/arch/sparc/vtophys.hh: Cleanup of full-system global variables, primarily in simple_cpu.cc, to allow multi-system simulations. (Multiple systems not yet yested though.) Also changes to build sim_smt in full-system mode (though with only SimpleCPU and not the full timing CPU for now). Still to do: minimize changes in SimpleCPU code between full-system and application modes... way too many ifdefs there. Much of the full-system stuff moved into SimpleCPU should be put in a new System object to allow multiprocessor simulations. Converted last remaining modules from C to C++ (mostly in /old). Renamed all .c files to .cc and a few .h files to .hh. Renamed architecture-specific files in arch/$TARGET from $TARGET.{cc,hh,def} to machine.{cc,hh,def} to get rid of pointless intermediate files in object directory. Split exo-specific definitions out of machine.hh into machine_exo.h. Specifics: In machine.def, null resource descriptors must be FUClamd_NA (and not NA) to pass C++ type checking. Enhanced error checking/reporting in bas src/arch/sparc/vtophys.cc: - Get rid of my String class, the Vector class, the bitvector class, and my doubly linked list class. - Convert tokenize, to_number (formerly StringToNumber) and eat_white to function on stl strings. - Change most cases of char * and const char * to string, or const string & - Some formatting and style nits, but not too many. src/arch/sparc/vtophys.cc: simplify src/arch/sparc/vtophys.cc: Renamed SimpleCPU::(read|write)_(byte|half|word|qword) to just read & write, overloaded on the type of the 'data' argument. Merged the full-system and non-full-system implementations of these eight original functions into two common template functions. To support this, also renamed (read|write)[1248] on memory_object and derivatives to just read & write, again overloaded on the type of the 'data' argument. Many of these functions could now be condensed into a few template functions (though with a level of indirection so that the interface can remain virtual). I did not do that though. src/arch/sparc/vtophys.cc: First pass at compiling with gcc 3.x. Lots of "std::" in header files, "using namespace std" in source files. (Note policy of not putting "using" statements in headers or before includes in sources.) Still not able to compile with gcc 3.2. Errors: - Can't create an ifstream from a file descriptor anymore (breaks IniFile). - "`class MSHR::MSHRegister' is private" errors in mshr.cc and prefetch_cache.cc: not clear why since it's in the public part of the class declaration. - cpu.cc:879: can't match a reference and 0 (specifically "no match for `bool ? SimObjectParam& : int' operator") - pipetrace.cc: "invalid conversion from `int' to `std::_Ios_Fmtflags'" Warnings: - strstream now deprecated... needs some rewriting in sat_counter.hh and hybrid_pred.hh (need to get all that code out of the headers anyway) - trace.hh macro problem: cpp now says 'pasting "::" and "Event" does not give a valid preprocessing token' - major "implicit typename" issues in base/sized.hh src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: Implement some interval statistics for full system mode. Create a callpal function that is called when a callpal occurs so it's easier to manipulate the statics. Rework the vtophys stuff to make it a bit cleaner. src/arch/sparc/vtophys.cc: src/arch/sparc/vtophys.hh: Get rid of almost all old-style object names.
