From abc76f20cb98c90e8dab416dd16dfd4a954013ba Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Mon, 23 Jul 2007 21:51:38 -0700 Subject: Major changes to how SimObjects are created and initialized. Almost all creation and initialization now happens in python. Parameter objects are generated and initialized by python. The .ini file is now solely for debugging purposes and is not used in construction of the objects in any way. --HG-- extra : convert_revision : 7e722873e417cb3d696f2e34c35ff488b7bff4ed --- src/cpu/o3/mips/cpu_builder.cc | 230 ++--------------------------------------- 1 file changed, 8 insertions(+), 222 deletions(-) (limited to 'src/cpu/o3/mips') diff --git a/src/cpu/o3/mips/cpu_builder.cc b/src/cpu/o3/mips/cpu_builder.cc index c6acc0bfb..6a30ff099 100644 --- a/src/cpu/o3/mips/cpu_builder.cc +++ b/src/cpu/o3/mips/cpu_builder.cc @@ -31,12 +31,13 @@ #include +#include "config/use_checker.hh" #include "cpu/base.hh" #include "cpu/o3/mips/cpu.hh" #include "cpu/o3/mips/impl.hh" #include "cpu/o3/mips/params.hh" #include "cpu/o3/fu_pool.hh" -#include "sim/builder.hh" +#include "params/DerivO3CPU.hh" class DerivO3CPU : public MipsO3CPU { @@ -46,229 +47,15 @@ class DerivO3CPU : public MipsO3CPU { } }; -BEGIN_DECLARE_SIM_OBJECT_PARAMS(DerivO3CPU) -
