Re: [PATCH 7 of 8] [powerpc] add PowerPC support to libxc

[Tristan Gingold]

Le Jeudi 13 Juillet 2006 00:55, Hollis Blanchard a écrit :
[...]

On ia64, we have created a tools/libxc/ia64 directory.
This is because we have a few ia64 specific files (at least 4).
This hasn't been merged yet but the idea seems to have already been discussed 
and accepted.
