From 016593f2e91564dc9d675ae42dfd37059f9b5589 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Tue, 21 Aug 2012 05:49:09 -0400 Subject: Clock: Make Tick unsigned and remove UTick This patch makes the Tick unsigned and removes the UTick typedef. The ticks should never be negative, and there was only one major issue with removing it, caused by the o3 CPU using a -1 as an initial value. The patch has no impact on any regressions. --- src/base/types.hh | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'src/base') diff --git a/src/base/types.hh b/src/base/types.hh index 3105059ed..ba6d53ad7 100644 --- a/src/base/types.hh +++ b/src/base/types.hh @@ -51,13 +51,11 @@ typedef int64_t Counter; /** - * Clock cycle count type. - * @note using an unsigned breaks the cache. + * Tick count type. */ -typedef int64_t Tick; -typedef uint64_t UTick; +typedef uint64_t Tick; -const Tick MaxTick = LL(0x7fffffffffffffff); +const Tick MaxTick = ULL(0xffffffffffffffff); /** * Address type -- cgit v1.2.3
