tree.c (integer_all_onesp): Test that both components are all 1s.
2013-05-06 Marc Glisse <marc.glisse@inria.fr>
* tree.c (integer_all_onesp) <COMPLEX_CST>: Test that both
components are all 1s.
(integer_minus_onep): New function.
* tree.h (integer_minus_onep): Declare it.
* fold-const.c (fold_binary_loc) <MULT_EXPR>: Test
integer_minus_onep instead of integer_all_onesp.
