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.
|
|
This patch adds an explicit function to get the underlying node as gcc
4.6.1 and 4.6.2 have issues otherwise.
|
|
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".

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
|
|
Another bunch of issues addressed.

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.

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.
|
|
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

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.

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.
|
|
This patch enables warnings for missing declarations. To avoid issues
with SWIG-generated code, the warning is only applied to non-SWIG
code.
|
|
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.

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])

This mechanism is useful for dumping output that is correlated with stats
dumping, but isn't tracked by the gem5 statistics.
|
|
|
|
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().
|
|
This patch adds a mechanism to collect run time samples for specific portions
of a benchmark, using work_begin and work_end pseudo instructions.It also enhances
the histogram stat to report geometric mean.

Default is '::', so no visible change unless it is overridden

This step makes it easy to replace the accessor functions
(which still access a global variable) with ones that access
per-thread curTick values.

Ran all the source files through 'perl -pi' with this script:
s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|;
s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|;
s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|;
Also did a little manual editing on some of the arch/*/isa_traits.hh files
and src/SConscript.

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.

Also, make Formulas work on AverageVector. First, Stat::Average (and thus
Stats::AverageVector) was broken when coming out of a checkpoint and on resets,
this fixes that. Formulas also didn't work with AverageVector, but added
support for that.

Enable more or less takes the place of check, but also allows stats to
do some other configuration. Prepare moves all of the code that readies
a stat for dumping into a separate function in preparation for supporting
serialization of certain pieces of statistics data.
While we're at it, clean up the visitor code and some of the python code.
