From a687671327dd2eb4d715745cce04a8f1c96e1fc1 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 12 Jun 2021 12:01:27 -0400 Subject: sim: rx: replace cycle-stats with common profile settings The common sim-profile option controls whether to keep track of runtime execution (like cycle count), so switch the rx-specific cycle-stats option over to that. --- sim/rx/ChangeLog | 8 ++++++++ sim/rx/README.txt | 4 ++-- sim/rx/config.in | 3 --- sim/rx/configure | 26 ++------------------------ sim/rx/configure.ac | 17 ----------------- sim/rx/mem.c | 2 +- sim/rx/rx.c | 32 ++++++++++++++++---------------- 7 files changed, 29 insertions(+), 63 deletions(-) diff --git a/sim/rx/ChangeLog b/sim/rx/ChangeLog index c358f7c..a368dc4 100644 --- a/sim/rx/ChangeLog +++ b/sim/rx/ChangeLog @@ -1,5 +1,13 @@ 2021-06-12 Mike Frysinger + * README.txt: Change cycle-stats to sim-profile. + * configure.ac: Delete cycle-stats. + * mem.c: Change CYCLE_STATS to WITH_PROFILE + * rx.c: Likewise. + * config.in, configure: Regenerate. + +2021-06-12 Mike Frysinger + * aclocal.m4, config.in, configure: Regenerate. 2021-06-12 Mike Frysinger diff --git a/sim/rx/README.txt b/sim/rx/README.txt index 496e6a1..5ebd574 100644 --- a/sim/rx/README.txt +++ b/sim/rx/README.txt @@ -7,8 +7,8 @@ If enabled, the simulator will keep track of how many cycles each instruction takes.
