2006-07-22Fixed subtract with carry, and started some work with floating point.Gabe Black
src/arch/sparc/isa/decoder.isa: fixed subc, subccc, added decoding for impdep1 to fit with ua2005, and started work on floating point. src/arch/sparc/isa/operands.isa: Added in floating point operands, and changed the numbering of operands. src/arch/sparc/regfile.hh: Fixed some memory errors related to floating point. --HG-- extra : convert_revision : fa0aef2021a5cf99f175fceeb533fe63eb5f805c

2006-07-21Minor functionality updates.Kevin Lim
SConstruct: Include an option to specify the CPUs being tested. src/cpu/SConscript: Checker isn't SMT right now, so don't do SMT tests with the O3CPU if we're using the checker. src/python/m5/objects/O3CPU.py: Include default options. Unfortunately FullO3Config.py is still needed because it specifies which FUPool is being used. tests/SConscript: Several minor updates (sorry for one commit). Updated the copyright and fixed some m5 style issues. Also added the ability to specify which CPUs to run the tests on. --HG-- extra : convert_revision : b0b801115705544ea02e572e31314f7bb8b5f0f2

2006-07-19Put regression tests back into m5. They are located in the "tests" ↵Kevin Lim
directory. The directory output and reference outputs have changed slightly. Now the directory is ALPHA_SE/test/<test>/<cpu_model>/, and for the reference stats <test>/ref/<arch>/<cpu_model> Right now only non-SMT SE regression tests have been added back in. The rest are pending getting SMT working, and consolidating the FS configuration files. Eventually support for different OSs can be added so you can specify which versions of the binary you want to run from one config file. Note: mp-test1 doesn't have any reference stats because MP mode doesn't currently work. The test itself should probably work once the code is fixed. SConstruct: Updates to allow for regression tests to work via the command line "scons build/ALPHA_SE/test/debug/quick" and such once again. src/cpu/SConscript: Keep a list of SMT supporting CPUs so that the regression tests can easily specify which CPUs to use if they are SMT only. --HG-- extra : convert_revision : 34e6286150aae8f316ae694f6c00be8f510522f2
