From 75fb5bb7e7604eb9547fecf17d31c5f8f7bc55fd 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. --- graphics/ilmbase/buildlink3.mk | 19 ++++++------------- 1 file changed, 6 insertions(+), 13 deletions(-) (limited to 'graphics/ilmbase') diff --git a/graphics/ilmbase/buildlink3.mk b/graphics/ilmbase/buildlink3.mk index 7787a338a00..fadc5e17a75 100644 --- a/graphics/ilmbase/buildlink3.mk +++ b/graphics/ilmbase/buildlink3.mk @@ -1,19 +1,12 @@ -# $NetBSD: buildlink3.mk,v 1.1.1.1 2007/11/30 21:50:22 wiz Exp $ +# $NetBSD: buildlink3.mk,v 1.2 2009/03/20 19:24:40 joerg Exp $ -BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH}+ -ILMBASE_BUILDLINK3_MK:= ${ILMBASE_BUILDLINK3_MK}+ +BUILDLINK_TREE+= ilmbase -.if ${BUILDLINK_DEPTH} == "+" -BUILDLINK_DEPENDS+= ilmbase -.endif +.if !defined(ILMBASE_BUILDLINK3_MK) +ILMBASE_BUILDLINK3_MK:= -BUILDLINK_PACKAGES:= ${BUILDLINK_PACKAGES:Nilmbase} -BUILDLINK_PACKAGES+= ilmbase -BUILDLINK_ORDER:= ${BUILDLINK_ORDER} ${BUILDLINK_DEPTH}ilmbase - -.if ${ILMBASE_BUILDLINK3_MK} == "+" BUILDLINK_API_DEPENDS.ilmbase+= ilmbase>=1.0.1 BUILDLINK_PKGSRCDIR.ilmbase?= ../../graphics/ilmbase -.endif # ILMBASE_BUILDLINK3_MK +.endif # ILMBASE_BUILDLINK3_MK -BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH:S/+$//} +BUILDLINK_TREE+= -ilmbase -- cgit v1.2.3
