Slight fixes, add in commit trace flag.
base/traceflags.py: Add new commit rate trace flag. build/SConstruct: Add extra option for efence. cpu/beta_cpu/alpha_full_cpu_impl.hh: Use function calls instead of direct indexing (avoids confusion). cpu/beta_cpu/commit_impl.hh: Add commit rate trace output (might not be worthwhile in the future). cpu/beta_cpu/decode_impl.hh: Remove some older hacks. Fix it so that the isntruction properly sets its next PC to the one calculated by the branch. cpu/beta_cpu/fetch_impl.hh: Remove old commented code. cpu/beta_cpu/iew_impl.hh: Add extra check to ensure that the instruction is valid. cpu/beta_cpu/regfile.hh: Include trace file. --HG-- extra : convert_revision : 4ee1dc88f8a5ed9b65486c6c111a3718a8040e42
