tree.c (integer_each_onep): New function.
2014-09-12 Marc Glisse <marc.glisse@inria.fr>
gcc/
* tree.c (integer_each_onep): New function.
* tree.h (integer_each_onep): Declare it.
* fold-const.c (fold_binary_loc): Use it for ~A + 1 to -A and
-A - 1 to ~A. Disable (X & 1) ^ 1, (X ^ 1) & 1 and ~X & 1 to
(X & 1) == 0 for vector and complex.
gcc/testsuite/
* gcc.dg/vec-andxor1.c: New file.
