From e06321091d4e931ff1a4d753e56d76f9746c3cd2 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Thu, 9 Oct 2008 04:58:24 -0700 Subject: eventq: convert all usage of events to use the new API. For now, there is still a single global event queue, but this is necessary for making the steps towards a parallelized m5. --- src/arch/sparc/miscregfile.cc | 13 ++++++++----- src/arch/sparc/miscregfile.hh | 5 +++-- src/arch/sparc/regfile.cc | 10 ++++++---- src/arch/sparc/regfile.hh | 5 +++-- src/arch/sparc/ua2005.cc | 30 +++++++++++++++++------------- 5 files changed, 37 insertions(+), 26 deletions(-) (limited to 'src/arch/sparc') diff --git a/src/arch/sparc/miscregfile.cc b/src/arch/sparc/miscregfile.cc index 195db90a6..d66cefa7a 100644 --- a/src/arch/sparc/miscregfile.cc +++ b/src/arch/sparc/miscregfile.cc @@ -593,7 +593,8 @@ void MiscRegFile::setReg(int miscReg, setRegNoEffect(miscReg, new_val);
