Some stuff aparently didn't get committed which was from before the new repository was created.
SConscript: There is a new SConscript in the arch/alpha directory which has the alpha specific files. To add files for an arch, a similar file should be created. arch/isa_parser.py: The isa parser now supports include directives. These are done with ##include build/SConstruct: The target directory is passed on so that the architecture specific SConscript can have it. Also, sparc was added as a valid architecture type. arch/alpha/SConscript: This SConscript adds the alpha specific source arch/sparc/isa_desc/operands.h: This sets up the operand types that the sparc isa uses arch/sparc/isa_traits.cc: Implementation of sparc specific things, like a register file with windows build/build_options/default/SPARC_SE: The default options for a sparc syscall emulation build. --HG-- extra : convert_revision : 1afedae61dc8cae0d59d3bf1d41420d929be2efd
