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

To build a version of statetrace suitable to run on a particular ISA, use a
target of the form build/<arch>/statetrace. For example, to build statetrace
for ARM binaries, run:
scons build/arm/statetrace
You may need a cross compiler in order to build statetrace successfully. To
specify an alternative compiler, set the CXX scons argument on the command
line. The CXX environment variable is NOT considered when selecting the
compiler. To override the compiler for a particular target ISA, set the
<arch>CXX scons argument. For example, to build both the AMD64 version and
the ARM version at the same time using the system compiler for the AMD64
version and a cross compiler for arm, your command line would look like the
following:
scons ARMCXX=arm-cross-g++ build/amd64/statetrace build/arm/statetrace
After a successful build, the statetrace binary(binaries) will be located in
the build/<arch>/ directories you specified on the command line.
