2018-02-13sim: Make Stats truly non-copy-constructibleRekai Gonzalez-Alberquilla
The stats are silently non-copy constructible. Therefore, when someone copy-constructs any object with stats, asserts happen when registering the stats, as they were not constructed in the intended way. This patch solves that by explicitly deleting the copy constructor, trading an obscure run-time assert for a compile-time somehow more meaningful error meassage. This triggers some compilation errors as the FaultStats in the fault definitions of ARM and SPARC use brace-enclosed initialisations in which one of the elements derives from DataWrap, which is not copy-constructible anymore. To fix that, this patch also adds a constructor for the FaultVals in both ISAs.

2016-07-21base: Add total() to Vector2D statDavid Guillen Fandos
This patch adds a total() function to the Vector2D stat type. Similar to other stats such as Scalar or Vector it is useful to be able to read the total for a given stat.
2014-10-20base: Fix for stats node on gcc < 4.6.3Andreas Hansson
This patch adds an explicit function to get the underlying node as gcc 4.6.1 and 4.6.2 have issues otherwise.
2014-10-16base: Use shared_ptr for stat NodeAndreas Hansson
This patch transitions the stat Node and its derived classes from the ad-hoc RefCountingPtr to the c++11 shared_ptr. There are no changes in behaviour, and the code modifications are mainly replacing "new" with "make_shared".
2014-10-16config: Add a --without-python option to build processAndrew Bardsley
Add the ability to build libgem5 without embedded Python or the ability to configure with Python. This is a prelude to a patch to allow config.ini files to be loaded into libgem5 using only C++ which would make embedding gem5 within other simulation systems easier. This adds a few registration interfaces to things which cross between Python and C++. Namely: stats dumping and SimObject resolving
2014-10-01misc: Fix issues identified by static analysisAndreas Hansson
Another bunch of issues addressed.
2014-09-20base: Clean up redundant string functions and use C++11Andreas Hansson
This patch does a bit of housekeeping on the string helper functions and relies on the C++11 standard library where possible. It also does away with our custom string hash as an implementation is already part of the standard library.
2014-09-19misc: Remove assertions ensuring unsigned values >= 0Andreas Hansson
2014-09-09misc: Fix a number of unitialised variables and membersAndreas Hansson
Static analysis unearther a bunch of uninitialised variables and members, and this patch addresses the problem. In all cases these omissions seem benign in the end, but at least fixing them means less false positives next time round.
2014-05-09stats: Method stats sourceStephan Diestelhorst
This source for stats binds an object and a method / function from the object to a stats object. This allows pulling out stats from object methods without needing to go through a global, or static shim. Syntax is somewhat unpleasant, but the templates and method pointer type specification were quite tricky. Interface is very clean though; and similar to .functor
2014-01-10stats: add function for adding two histogramsNilay Vaish
This patch adds a function to the HistStor class for adding two histograms. This functionality is required for Ruby. It also adds support for printing histograms in a single line.

gcc/g++ 4.4.7 complained about the operator= being undefined. This changeset adds the operator.

2013-02-19scons: Fix warnings issued by clang 3.2svn (XCode 4.6)Andreas Hansson
This patch fixes the warnings that clang3.2svn emit due to the "-Wall" flag. There is one case of an uninitialised value in the ARM neon ISA description, and then a whole range of unused private fields that are pruned.
2013-02-19scons: Add warning for missing declarationsAndreas Hansson
This patch enables warnings for missing declarations. To avoid issues with SWIG-generated code, the warning is only applied to non-SWIG code.
2013-02-19scons: Fix up numerous warnings about name shadowingAndreas Hansson
This patch address the most important name shadowing warnings (as produced when using gcc/clang with -Wshadow). There are many locations where constructor parameters and function parameters shadow local variables, but these are left unchanged.
2012-06-05stats: when applying an operation to two vectors sum the components first.William Wang
Previously writing X/Y in a formula would result in: x[0]/y[0] + x[1]/y[1] In reality you want: (x[0] +x[1])/(y[0] + y[1])
2012-06-05stats: Provide a mechanism to get a callback when stats are dumped.Mitchell Hayenga
This mechanism is useful for dumping output that is correlated with stats dumping, but isn't tracked by the gem5 statistics.

2012-05-10stats: track if the stats have been enabled and prevent requesting master idAli Saidi
Track the point in the initialization where statistics have been registered. After this point registering new masterIds can no longer work as some SimObjects may have sized stats vectors based on the previous value. If someone tries to register a masterId after this point the simulator executes fatal().
2012-01-09sim: Enable sampling of run-time for code-sections marked using pseudo insts.Prakash Ramrakhyani

bkt size isn't evenly divisible by max-min and it would round down, it's possible to sample a distribution and have no place to put the sample. When this case occured the simulator would assert.
