From 29f82f265aa7085eaf0659be8f67b2a95f5326e5 Mon Sep 17 00:00:00 2001 From: Polina Dudnik Date: Mon, 11 May 2009 10:38:46 -0700 Subject: ruby: Removed g_SIMULATING flag 1. removed checks from tester files 2. removed else clause in Sequencer and DirectoryMemory else clause is needed by the tester, it is up to Derek to revive it elsewhere when he gets to it Also: 1. Changed m_entries in DirectoryMemory to a map 2. And replaced SIMICS_read_physical_memory with a call to now-dummy Derek's-to-be readPhysMem function --- src/mem/ruby/config/config.hh | 1 - src/mem/ruby/config/rubyconfig.defaults | 1 - src/mem/ruby/config/tester.defaults | 1 - src/mem/ruby/system/DirectoryMemory.cc | 49 +++++----- src/mem/ruby/system/DirectoryMemory.hh | 5 +- src/mem/ruby/system/Sequencer.cc | 151 ++--------------------------- src/mem/ruby/tester/DeterministicDriver.cc | 4 - src/mem/ruby/tester/RaceyDriver.cc | 4 - src/mem/ruby/tester/SyntheticDriver.cc | 5 - src/mem/ruby/tester/Tester.cc | 4 - src/mem/ruby/tester/main.cc | 4 - 11 files changed, 35 insertions(+), 194 deletions(-) (limited to 'src') diff --git a/src/mem/ruby/config/config.hh b/src/mem/ruby/config/config.hh index 3c3d87ef5..3cad258a2 100644 --- a/src/mem/ruby/config/config.hh +++ b/src/mem/ruby/config/config.hh @@ -134,7 +134,6 @@ PARAM_BOOL( REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH );
