From e16bf922524bb46f00bfc8f77ccf42e59eff989b Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 28 Dec 2013 18:39:11 +0100 Subject: [PATCH] Makefile: expose target 'graph-build' to generate the build-time graphs Generate the build-time graphs by calling: make graph-build This generates the graphs in $(O)/graphs/ It is possible to use the alternate color-scheme by setting the variable GRAPH_ALT=1 on the command line: make GRAPH_ALT=1 graph-build Signed-off-by: "Yann E.
