Use Alias in common.opt to make -ftree-loop-linear an alias of -floop-interchange.
2011-01-31 Sebastian Pop <sebastian.pop@amd.com>
* common.opt (ftree-loop-linear): Use Alias to make it an alias of
-floop-interchange.
* invoke.texi (-ftree-loop-linear): Make it clear that this flag
is an alias of -floop-interchange and that it requires the
Graphite infrastructure.
* tree-ssa-loop.c (gate_graphite_transforms): Do not set
flag_loop_interchange based on the value of flag_tree_loop_linear.
