Initial light-weight OoO CPU checkin, along with gcc-3.4 fixes.
SConscript: Include new files. arch/alpha/isa_desc: Make the eaCompPtr and memAccPtr non-const so that execute() can be called on them. arch/alpha/isa_traits.hh: Add enum for total number of data registers. arch/isa_parser.py: base/traceflags.py: Include new light-weight OoO CPU model. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: Changes to abstract more away from the base dyn inst class. cpu/beta_cpu/2bit_local_pred.cc: cpu/beta_cpu/2bit_local_pred.hh: cpu/beta_cpu/tournament_pred.cc: cpu/beta_cpu/tournament_pred.hh: Remove redundant SatCounter class. cpu/beta_cpu/alpha_dyn_inst.cc: cpu/beta_cpu/alpha_full_cpu.cc: cpu/beta_cpu/alpha_full_cpu.hh: cpu/beta_cpu/bpred_unit.cc: cpu/beta_cpu/inst_queue.cc: cpu/beta_cpu/mem_dep_unit.cc: cpu/beta_cpu/ras.cc: cpu/beta_cpu/rename_map.cc: cpu/beta_cpu/rename_map.hh: cpu/beta_cpu/rob.cc: Fix for gcc-3.4 cpu/beta_cpu/alpha_dyn_inst.hh: cpu/beta_cpu/alpha_dyn_inst_impl.hh: Fixes for gcc-3.4. Include more variables and functions that are specific to AlphaDynInst which were once in BaseDynInst. cpu/beta_cpu/alpha_full_cpu_builder.cc: Make params match the current params inherited from BaseCPU. cpu/beta_cpu/alpha_full_cpu_impl.hh: Fixes for gcc-3.4 cpu/beta_cpu/full_cpu.cc: Use new params pointer in BaseCPU. Fix for gcc-3.4. cpu/beta_cpu/full_cpu.hh: Use new params class from BaseCPU. cpu/beta_cpu/iew_impl.hh: Remove unused function. cpu/simple_cpu/simple_cpu.cc: Remove unused global variable. cpu/static_inst.hh: Include OoODynInst for new lightweight OoO CPU --HG-- extra : convert_revision : 34d9f2e64ca0313377391e0d059bf09c040286fa
