From 2d1ba244e90207d03eef397a99aa4091baeec5b3 Mon Sep 17 00:00:00 2001 From: joerg Date: Fri, 20 Mar 2009 19:23:50 +0000 Subject: Simply and speed up buildlink3.mk files and processing. This changes the buildlink3.mk files to use an include guard for the recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS, BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of enter/exit marker, which can be used to reconstruct the tree and to determine first level includes. Avoiding := for large variables (BUILDLINK_ORDER) speeds up parse time as += has linear complexity. The include guard reduces system time by avoiding reading files over and over again. For complex packages this reduces both %user and %sys time to half of the former time. --- audio/liba52/buildlink3.mk | 19 ++++++------------- 1 file changed, 6 insertions(+), 13 deletions(-) (limited to 'audio/liba52/buildlink3.mk') diff --git a/audio/liba52/buildlink3.mk b/audio/liba52/buildlink3.mk index cddd09dde9a..afd3c39afe8 100644 --- a/audio/liba52/buildlink3.mk +++ b/audio/liba52/buildlink3.mk @@ -1,20 +1,13 @@ -# $NetBSD: buildlink3.mk,v 1.7 2006/07/08 23:10:36 jlam Exp $ +# $NetBSD: buildlink3.mk,v 1.8 2009/03/20 19:23:54 joerg Exp $ -BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH}+ -LIBA52_BUILDLINK3_MK:= ${LIBA52_BUILDLINK3_MK}+ +BUILDLINK_TREE+= liba52 -.if !empty(BUILDLINK_DEPTH:M+) -BUILDLINK_DEPENDS+= liba52 -.endif +.if !defined(LIBA52_BUILDLINK3_MK) +LIBA52_BUILDLINK3_MK:= -BUILDLINK_PACKAGES:= ${BUILDLINK_PACKAGES:Nliba52} -BUILDLINK_PACKAGES+= liba52 -BUILDLINK_ORDER:= ${BUILDLINK_ORDER} ${BUILDLINK_DEPTH}liba52 - -.if !empty(LIBA52_BUILDLINK3_MK:M+) BUILDLINK_API_DEPENDS.liba52+= liba52>=0.7.4 BUILDLINK_ABI_DEPENDS.liba52+= liba52>=0.7.4nb3 BUILDLINK_PKGSRCDIR.liba52?= ../../audio/liba52 -.endif # LIBA52_BUILDLINK3_MK +.endif # LIBA52_BUILDLINK3_MK -BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH:S/+$//} +BUILDLINK_TREE+= -liba52 -- cgit v1.2.3
