2004-02-09Add LRU aligned copies to the hierarchy, with only one outstanding copy. ↵Erik Hallnor
Aligned copies now fully work in LRU (just need to write the IIC doCopy call).

2004-02-04Add support for "serializing" instructions that flushSteve Reinhardt
execution pipeline (Alpha trapb & excb). Add support for write memory barriers (mostly impacts store buffer). Add StaticInst flag to indicate memory barriers, though this is not modeled in the pipeline yet. arch/alpha/isa_desc: Implement trapb, excb, mb, and wmb as insts with no execution effect (empty execute() function) but with flags that indicate their side effects. Also make sure every instruction that needs to go to the execute stage has a real opClass value, since we are now using No_OpClass to signal insts that can get dropped at dispatch. StaticInst::branchTarget() is now a const method. cpu/static_inst.hh: Add flags to indicate serializing insts (trapb, excb) and memory and write barriers. Also declare some StaticInst methods as const methods. dev/etherlink.hh: sim/eventq.hh: sim/serialize.cc: sim/serialize.hh: sim/sim_object.hh: Make name() return value const. --HG-- extra : convert_revision : 39520e71469fa20e0a7446b2e06b494eec17a02c

This pass catches the rest (mostly STL and uint*_t types). base/cprintf_formats.hh: cpu/simple_cpu/simple_cpu.cc: sim/serialize.cc: sim/serialize.hh: Change "foo_t& foo" to "foo_t &foo". --HG-- extra : convert_revision : fc7f7425db2aef33e490f952b5ce74c8c36d0d41

This primarily to be internally consistent (sometimes we used one, sometimes the other, even within the same line of code!).

This lets us centralize priorities so we can see what's going on. - Shift serialize & cpu-switch events to happen before CPU ticks (to be consistent with starting new CPU on same cycle instead of next cycle). - Get rid of unnecessary bus stats reset callback. cpu/simple_cpu/simple_cpu.cc: sim/debug.cc: sim/eventq.hh: sim/serialize.cc: sim/sim_events.cc: sim/sim_events.hh: Switch events to use a priority enum instead of integers.

interfaces, and specific support for Alpha Linux. Split syscall emulation functions into several groups, based on whether they depend on the specific OS and/or architecture (and all combinations of above), including the use of template functions to support syscalls with slightly different constants or interface structs. arch/alpha/alpha_tru64_process.cc: Incorporate full Tru64 object definition here, including structure and constant definitions. This way we can wrap all of the functions inside the object, and not worry about namespace conflicts because no one outside this file will ever see it. base/loader/aout_object.cc: base/loader/aout_object.hh: base/loader/ecoff_object.cc: base/loader/ecoff_object.hh: base/loader/elf_object.cc: base/loader/elf_object.hh: base/loader/object_file.cc: base/loader/object_file.hh: Add enums to ObjectFile to indicate the object's architecture and operating system. cpu/exec_context.cc: prog.hh is now process.hh cpu/exec_context.hh: prog.hh is now process.hh move architecture-specific syscall arg accessors into ExecContext cpu/simple_cpu/simple_cpu.cc: No need to include prog.hh (which has been renamed) sim/process.cc: sim/process.hh: LiveProcess is now effectively an abstract base class.
