Adding what was tracedump but is now statetrace to the tree. Let me know if statetrace is also already taken. util/statetrace/Makefile: Makefile to build statetrace. Targets are: statetrace: alias to build using the "native" compiler statetrace-native: use the native compiler statetrace-sparc: use the sparc cross compiler I'll make this a little more fancy and capable later. util/statetrace/arch/tracechild_i386.cc: Implementation of i386 support util/statetrace/arch/tracechild_i386.hh: Declaration of i386 support util/statetrace/arch/tracechild_sparc.cc: implementation of SPARC support util/statetrace/arch/tracechild_sparc.hh: declaration of SPARC support util/statetrace/printer.cc: Implementation of the "Printer" objects which parse and output the state of the process after each instruction. There are currently two types of printers, nested ones and register ones. These are called NestingPrinter and RegPrinter respectively. util/statetrace/printer.hh: Declaration of "Printer" objects util/statetrace/refcnt.hh: This is copied from m5. I should use the one already in the tree, but I'll do that later. util/statetrace/regstate.hh: Interface for accessing registers. util/statetrace/statetrace.cc: Main file with argument parsing and the "main" function which contains the tracing loop. util/statetrace/tracechild.cc: Implementation of the base tracechild class. util/statetrace/tracechild.hh: Declaration of the base tracechild class. util/statetrace/tracechild_arch.cc: This file hooks in support for the appropriate architecture. Just the implementation is brought in, since the main program should ideally not have to know anything at all about an architecture other than it's interface. util/statetrace/x86.format: An example output template for x86. A few example SPARC templates will be added later. --HG-- extra : convert_revision : 7c8bf8230907aba42ed1e707b9ca2d6da0d4e6d4
