Put everything as globals in the Statistics::Database namespace. allocate unique ids for all stats. directly implement the check routine and get rid of the various dumping routines since they're now in separate files. make sure that no two stats have the same name clean up some loops base/statistics.hh: major changes to the statistics package again lots of code was factored out of statistics.hh into several separate files in base/stats/ (this will continue) There are now two Stat package types Result and Counter that are specified to allow the user to keep the counted type separate from the result type. They are currently both doubles but that's an experiment. There is no more per stat ability to set the type. Statistics::Counter is not the same as Counter! Implement a visitor for statistics output so that new output types can be implemented independently from the stats package itself. Add a unique id to each stat so that it can be used to keep track of stats more simply. This number can also be used in debugging problems with stats. Tweak the bucket size stuff a bit to make it work better. fixed VectorDist size bug cpu/memtest/memtest.cc: Fix up for changes in stats package Don't use value() since it doesn't work with binning. If you want a number as a stat, and to use it in the program itself, you really want two separate variables, one that's a stat, and one that's not. cpu/memtest/memtest.hh: Fix up for changes in stats package test/Makefile: Try to build stuff now that directories matter test/stattest.cc: test all new output types choose which one with command line options --HG-- extra : convert_revision : e3a3f5f0828c67c0e2de415d936ad240adaddc89
