Subject: [PATCH 7/8] Enable "cross-compile"
|
|
|
9cc17c |
|
|
|
9cc17c |
This adds support for building ATLAS without running any target code. In
|
|
|
9cc17c |
order for this to work, the archdefs must contain some additional files
|
|
|
9cc17c |
that would otherwise be built during various tuning steps; see the new
|
|
|
9cc17c |
targets extra_get and extra_put in "CONFIG/ARCHS/Makefile".
|
|
|
9cc17c |
|
|
|
9cc17c |
Even if the archdefs contain these additional files, cross compilation
|
|
|
9cc17c |
is *not* automatically enabled. To activate it and disable tuning at
|
|
|
9cc17c |
build time, add the option "-Si archdef 2" when running "configure".
