This changes allows us to compile the gem5 simulator with ag++. It was tested with ag++ v0.8, built Apr 18 2013. Most of the changes are preprocessor directives like #ifndef __puma which have been inserted into the gem5 code. Unfortunately, a python script and a SWIG input file have been patched, too. Additionally, the CMake file has been updated. A single call to "make" now invokes the ag++ (instead of the g++) compiler front end. The new CMake target "gem5-allclean" should be used to clean the current project when building FailGem5. In addition to cleaning the Fail build directory, it also invokes "scons -c" in the gem5 build directory; that is, gem5 is cleaned as well. Change-Id: I20a92f025f34f626b81e30f2c873baeba189f83b

# FIXMEs:
|
|
# - incremental builds working?
|
|
# - dependency for modified .cc files not correctly checked
|
|
# - core_count should be derived from the parent make -jX parameter
|
|
# - make gem5_build_config configurable in CMake
|
|
# (alternative: gem5_build_config is set based on the CMake build
|
|
# config, e.g., "Debug" or "Release")
|
|
# - Ideally, there is no additional "gem5-clean" target. Instead,
|
|
# calling "make clean" should also invoke a clean command in the
|
|
# gem5 root dir. This seems easy for "make only" projects--things
|

# get shaky due to "scons".
