From 45f650eab03f1b50fd5f8b1bad5635902ed5192a Mon Sep 17 00:00:00 2001 From: simonmar Date: Tue, 19 Dec 2000 14:30:17 +0000 Subject: [PATCH] [project @ 2000-12-19 14:30:17 by simonmar] - implement +RTS -t (one-line GC stats) - clean up: use integer variables (counting ticks) rather than doubles to store time values, and only call times() once on entry & exit from GC instead of twice. Carry on using times() rather than gettimeofday(), since we don't really need the increased accuracy. --- ghc/rts/Stats.c | 529 ++++++++++++++++++++++++++++--------------------------- 1 file changed, 267 insertions(+), 262 deletions(-) diff --git a/ghc/rts/Stats.c b/ghc/rts/Stats.c index f8768db..ceaaaa7 100644 --- a/ghc/rts/Stats.c +++ b/ghc/rts/Stats.c @@ -1,5 +1,5 @@ /* ----------------------------------------------------------------------------- - * $Id: Stats.c,v 1.22 2000/12/04 12:31:21 simonmar Exp $ + * $Id: Stats.c,v 1.23 2000/12/19 14:30:17 simonmar Exp $ * * (c) The GHC Team, 1998-1999 * @@ -58,34 +58,47 @@ /* huh? */ #define BIG_STRING_LEN 512 -static double ElapsedTimeStart = 0.0; -static double TicksPerSecond = 0.0; +/* We're not trying to be terribly accurate here, using the + * basic times() function to get a resolution of about 100ths of a + * second, depending on the OS.
