b9bc530ad2 Regression: Add ANSI colours to highlight test status
This patch adds a very basic pretty-printing of the test status
(passed or failed) to highlight failing tests even more: green for
passed, and red for failed. The printing only uses ANSI it the target
output is a tty and supports ANSI colours. Hence, any regression
scripts that are outputting to files or sending e-mails etc should
still be fine.

b6aa6d55eb clang/gcc: Fix compilation issues with clang 3.0 and gcc 4.6
This patch addresses a number of minor issues that cause problems when
compiling with clang >= 3.0 and gcc >= 4.6. Most importantly, it
avoids using the deprecated ext/hash_map and instead uses
unordered_map (and similarly so for the hash_set). To make use of the
new STL containers, g++ and clang has to be invoked with "-std=c++0x",
and this is now added for all gcc versions >= 4.6, and for clang >=
3.0. For gcc >= 4.3 and <= 4.5 and clang <= 3.0 we use the tr1
unordered_map to avoid the deprecation warning.

The addition of c++0x in turn causes a few problems, as the
compiler is more stringent and adds a number of new warnings. Below,
the most important issues are enumerated:

1) the use of namespaces is more strict, e.g. for isnan, and all
   headers opening the entire namespace std are now fixed.

2) another other issue caused by the more stringent compiler is the
   narrowing of the embedded python, which used to be a char array,
   and is now unsigned char since there were values larger than 128.

3) a particularly odd issue that arose with the new c++0x behaviour is
   found in range.hh, where the operator< causes gcc to complain about
   the template type parsing (the "<" is interpreted as the beginning
   of a template argument), and the problem seems to be related to the
   begin/end members introduced for the range-type iteration, which is
   a new feature in c++11.

As a minor update, this patch also fixes the build flags for the clang
debug target that used to be shared with gcc and incorrectly use
"-ggdb".

3418ebb5f8 SConstruct: rename and document AddM5Option
Got rid of gratuitous M5 reference in the function name.
In the process, wondered why we have this function at all and
spent time trying to get rid of it and eventually firgured out
why it's needed.  Put the answer in a comment so we don't have
to wonder again.

7d4f187700 clang: Enable compiling gem5 using clang 2.9 and 3.0
This patch adds the necessary flags to the SConstruct and SConscript
files for compiling using clang 2.9 and later (on Ubuntu et al and OSX
XCode 4.2), and also cleans up a bunch of compiler warnings found by
clang. Most of the warnings are related to hidden virtual functions,
comparisons with unsigneds >= 0, and if-statements with empty
bodies. A number of mismatches between struct and class are also
fixed. clang 2.8 is not working as it has problems with class names
that occur in multiple namespaces (e.g. Statistics in
kernel_stats.hh).

clang has a bug (http://llvm.org/bugs/show_bug.cgi?id=7247) which
causes confusion between the container std::set and the function
Packet::set, and this is currently addressed by not including the
entire namespace std, but rather selecting e.g. "using std::vector" in
the appropriate places.

c2dbfc1d6c MAC: Make gem5 compile and run on MacOSX 10.7.2
Adaptations to make gem5 compile and run on OSX 10.7.2, with a stock
gcc 4.2.1 and the remaining dependencies from macports, i.e. python
2.7,.2 swig 2.0.4, mercurial 2.0. The changes include an adaptation of
the SConstruct to handle non-library linker flags, and Darwin-specific
code to find the memory usage of gem5. A number of Ruby files relied
on ambigious uint (without the 32 suffix) which caused compilation
errors.

1b49c56679 Scons: Drop RUBY as compile time option.

is 'None', then Ruby is not compiled.

5a78c2d001 SConstruct: automatically update .hg/hgrc with style hooks.
Seems easier than pestering people about it.
Note also that path is now absolute, so you don't get errors
when invoking hg from subdirectories.
Also whacked unused mercurial_bin_not_found message (the
code that used this was deleted a couple months ago in
rev 5138d1e453f1).

8ce85d3db6 scons: interpret paths relative to launch directory
Make sure all command-line targets and EXTRAS directories
are interpreted relative to the launch directory.  This
turns out to be very useful when building code from an
EXTRAS directory using SCons's -C option.

We were trying to do this with targets but it didn't actually
work since we didn't update BUILD_TARGETS (so SCons got
confused internally).  We weren't even trying with EXTRAS.

To simplify the code, the default target is also interpreted
relative to the launch dir even though it was explicitly
handled as relative to the m5 dir before... I doubt anyone
really uses this anyway so it didn't seem worth the complexity.
(Maybe we should get rid of it?)

f713af951a scons: allow use of current builds as default build settings
Currently the --default= option only looks at the predefined
build configs (in m5/build_opts), so you're limited to basing
a new build config off of those (ALPHA_SE, etc.).  If you've
already defined a non-standard build config and want to clone
it or tweak it, you have to start from scratch.  This patch
causes --default= to look first among the existing builds
(in build/variables) before looking in build_opts so you
can specify an existing non-standard build config as a
starting point for a new config.

38aa50bb49 base: disable FastAlloc in debug builds by default
FastAlloc's reuse policies can mask allocation bugs, so
we typically want it disabled when debugging.  Set
FORCE_FAST_ALLOC to enable even when debugging, and set
NO_FAST_ALLOC to disable even in non-debug builds.

02f10fbdc8 SCons: Stop embedding the mercurial revision into the binary.
This causes a lot of rebuilds that could have otherwise possibly been
avoided, and, more annoyingly, a lot of unnecessary rerunning of the
regressions. The benefits of having the revision in the output haven't
materialized, so this change removes it.

9e608a6ad7 SCons: Separately label the global non-sticky options.
The global sticky options were being printed with a heading, and then the
global nonsticky options were being printed immediately after them without a
heading. Because the two lists ran together and the first had its own heading,
it looked like -all- those options where sticky even though some of them
aren't. This change adds a label to the second list so it's clear they're
different.

d650f4138e scons: show sources and targets when building, and colorize output.
I like the brevity of Ali's recent change, but the ambiguity of
sometimes showing the source and sometimes the target is a little
confusing.  This patch makes scons typically list all sources and
all targets for each action, with the common path prefix factored
out for brevity.  It's a little more verbose now but also more
informative.

Somehow Ali talked me into adding colors too, which is a whole
'nother story.

clean up the code a little bit while we're at it.

I recommend that everyone adds the pre-qrefresh hook below since it
will make qref run the style hook and not just commit/qpush

style = <m5 path>/util/style.py

pretxncommit.style = python:style.check_whitespace

de904a6d39 SCons: Make --help reflect the arguments to scons.
The arguments were added to the global_sticky_vars Variables object after the
basic help text was generated. As a result, the "actual:" value wouldn't
reflect the arguments to scons and wouldn't really be the "actual" value used
by the build. This change fixes that by updating global_sticky_vars slightly
earlier.

7311fd7182 ruby: Migrate all of ruby and slicc to SCons.
Add the PROTOCOL sticky option sets the coherence protocol that slicc
will parse and therefore ruby will use.  This whole process was made
difficult by the fact that the set of files that are output by slicc
are not easily known ahead of time.  The easiest thing wound up being
to write a parser for slicc that would tell me.  Incidentally this
means we now have a slicc grammar written in python.
