Large update of several parts of my code. The most notable change is the inclusion of a full-fledged load/store queue. At the moment it still has some issues running, but most of the code is hopefully close to the final version.
SConscript: arch/isa_parser.py: cpu/base_dyn_inst.cc: Remove OOO CPU stuff. arch/alpha/faults.hh: Add fake memory fault. This will be removed eventually. arch/alpha/isa_desc: Change EA comp and Mem accessor to be const StaticInstPtrs. cpu/base_dyn_inst.hh: Update read/write calls to use load queue and store queue indices. cpu/beta_cpu/alpha_dyn_inst.hh: Change to const StaticInst in the register accessors. cpu/beta_cpu/alpha_dyn_inst_impl.hh: Update syscall code with thread numbers. cpu/beta_cpu/alpha_full_cpu.hh: Alter some of the full system code so it will compile without errors. cpu/beta_cpu/alpha_full_cpu_builder.cc: Created a DerivAlphaFullCPU class so I can instantiate different CPUs that have different template parameters. cpu/beta_cpu/alpha_full_cpu_impl.hh: Update some of the full system code so it compiles. cpu/beta_cpu/alpha_params.hh: cpu/beta_cpu/fetch_impl.hh: Remove asid. cpu/beta_cpu/comm.hh: Remove global history field. cpu/beta_cpu/commit.hh: Comment out rename map. cpu/beta_cpu/commit_impl.hh: Update some of the full system code so it compiles. Also change it so that it handles memory instructions properly. cpu/beta_cpu/cpu_policy.hh: Removed IQ from the IEW template parameter to make it more uniform. cpu/beta_cpu/decode.hh: Add debug function. cpu/beta_cpu/decode_impl.hh: Slight updates for decode in the case where it causes a squash. cpu/beta_cpu/fetch.hh: cpu/beta_cpu/rob.hh: Comment out unneccessary code. cpu/beta_cpu/full_cpu.cc: Changed some of the full system code so it compiles. Updated exec contexts and so forth to hopefully make multithreading easier. cpu/beta_cpu/full_cpu.hh: Updated some of the full system code to make it compile. cpu/beta_cpu/iew.cc: Removed IQ from template parameter to IEW. cpu/beta_cpu/iew.hh: Removed IQ from template parameter to IEW. Updated IEW to recognize the Load/Store queue. cpu/beta_cpu/iew_impl.hh: New handling of memory instructions through the Load/Store queue. cpu/beta_cpu/inst_queue.hh: Updated comment. cpu/beta_cpu/inst_queue_impl.hh: Slightly different handling of memory instructions due to Load/Store queue. cpu/beta_cpu/regfile.hh: Updated full system code so it compiles. cpu/beta_cpu/rob_impl.hh: Moved some code around; no major functional changes. cpu/ooo_cpu/ooo_cpu.hh: Slight updates to OOO CPU; still does not work. cpu/static_inst.hh: Remove OOO CPU stuff. Change ea comp and mem acc to return const StaticInst. kern/kernel_stats.hh: Extra forward declares added due to compile error. --HG-- extra : convert_revision : 594a7cdbe57f6c2bda7d08856fcd864604a6238e
