The changes largely are fixing up the memory accesses to use ports/Requests/Packets, supporting the splitting off of instantiation of template classes, and handling some of the reorganization that happened.
OzoneCPU is untested for now but at least compiles. Fixes will be coming shortly.
SConstruct:
Remove OzoneSimpleCPU from list of CPUs.
src/cpu/SConscript:
Leave out OzoneSimpleCPU.
src/cpu/ozone/bpred_unit.cc:
Fixes to get OzoneCPU to compile.

# SCons top-level build description (SConstruct) file.
|
|
#
|
|
# While in this directory ('m5'), just type 'scons' to build the default
|
|
# configuration (see below), or type 'scons build/<CONFIG>/<binary>'
|
|
# to build some other configuration (e.g., 'build/ALPHA_FS/m5.opt' for
|
|
# the optimized full-system version).
|
|
#
|
|
# You can build M5 in a different directory as long as there is a
|
|
# 'build/<CONFIG>' somewhere along the target path. The build system
|
|
# expects that all configs under the same build directory are being
|
|
# built for the same host system.
|
|
#
|
|
# Examples:
|
|
#
|
|
# The following two commands are equivalent. The '-u' option tells
|
|
# scons to search up the directory tree for this SConstruct file.
|
|
# % cd <path-to-src>/m5 ; scons build/ALPHA_FS/m5.debug
|
|
# % cd <path-to-src>/m5/build/ALPHA_FS; scons -u m5.debug
|
|
#
|
|
# The following two commands are equivalent and demonstrate building
|
|
# in a directory outside of the source tree. The '-C' option tells
|
|
# scons to chdir to the specified directory to find this SConstruct
|
|
# file.
|
|
# % cd <path-to-src>/m5 ; scons /local/foo/build/ALPHA_FS/m5.debug
|
|
# % cd /local/foo/build/ALPHA_FS; scons -C <path-to-src>/m5 m5.debug
|
|
#
|
|
# You can use 'scons -H' to print scons options. If you're in this
|
|
# 'm5' directory (or use -u or -C to tell scons where to find this
|
|
# file), you can use 'scons -h' to print all the M5-specific build
|
|
# options as well.
