From 5f91ec3f4618dad8d36efbf8b5a5112a1ce0d1b7 Mon Sep 17 00:00:00 2001 From: Min Kyu Jeong Date: Mon, 23 Aug 2010 11:18:40 -0500 Subject: ARM/O3: store the result of the predicate evaluation in DynInst or Threadstate. THis allows the CPU to handle predicated-false instructions accordingly. This particular patch makes loads that are predicated-false to be sent straight to the commit stage directly, not waiting for return of the data that was never requested since it was predicated-false. --- src/cpu/thread_context.hh | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/cpu/thread_context.hh') diff --git a/src/cpu/thread_context.hh b/src/cpu/thread_context.hh index 78ecdacf2..7f6d258ab 100644 --- a/src/cpu/thread_context.hh +++ b/src/cpu/thread_context.hh @@ -404,6 +404,11 @@ class ProxyThreadContext : public ThreadContext void setNextMicroPC(uint64_t val) { actualTC->setNextMicroPC(val); } + bool readPredicate() { return actualTC->readPredicate(); } + + void setPredicate(bool val) + { actualTC->setPredicate(val); } + MiscReg readMiscRegNoEffect(int misc_reg) { return actualTC->readMiscRegNoEffect(misc_reg); } -- cgit v1.2.3
