From 47be081dc18f47e8b4955721c3db3812adf475d9 Mon Sep 17 00:00:00 2001 From: Marius Mauch Date: Fri, 24 Mar 2006 18:14:00 +0000 Subject: Replacing arch specific make.conf files with patches for the fallback make.conf which should be applied in the ebuild. Add a helper script to update patches if the main make.conf is changed. svn path=/main/trunk/; revision=2987 --- cnf/make.conf.ppc64.diff | 69 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 cnf/make.conf.ppc64.diff (limited to 'cnf/make.conf.ppc64.diff') diff --git a/cnf/make.conf.ppc64.diff b/cnf/make.conf.ppc64.diff new file mode 100644 index 000000000..fa3f20d0a --- /dev/null +++ b/cnf/make.conf.ppc64.diff @@ -0,0 +1,69 @@ +--- make.conf 2006-03-19 18:40:11.000000000 +0100 ++++ make.conf.ppc64 2006-03-19 18:26:21.000000000 +0100 +@@ -23,6 +23,13 @@ + # Example: + #USE="X gtk gnome -alsa" + ++# Host Setting ++# ============ ++# ++# All PowerPC64 systems should use this host setting: ++ ++CHOST="powerpc64-unknown-linux-gnu" ++ + # Host and optimization settings + # ============================== + # +@@ -33,9 +40,38 @@ + # package (and in some cases the libraries it uses) at default optimizations + # before reporting errors to developers. + # +-# Please refer to the GCC manual for a list of possible values. ++# -mtarget= for PowerPC64 systems instructs the gcc compiler that ++# it can use instruction scheduling specific for that type of processor ++# specified ++# ++# -mcpu= for PowerPC64 systems selects the type of processor you want ++# to optimize your code for.
