2004-02-09Add support for memory barriers.Steve Reinhardt
arch/alpha/isa_desc: Add cache port bindings for mb & wmb. --HG-- extra : convert_revision : 72f76150fe471d0dc97bd41598cad4d86a035e39
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
2004-02-03Fix bug: forgot branchTarget() method on indirect branches.Steve Reinhardt

2004-02-02Change "Foo& foo" declarations to "Foo &foo".Steve Reinhardt
This primarily to be internally consistent (sometimes we used one, sometimes the other, even within the same line of code!).
