re PR tree-optimization/34769 (gcc.dg/vect/no-vfa-pr29145.c)
2008-01-16 Richard Guenther <rguenther@suse.de> PR tree-optimization/34769 * tree-data-ref.c (initialize_matrix_A): Revert fix for PR34458. * tree.c (int_cst_value): Instead make this function more permissive in what it accepts as valid input. Document this function always sign-extends the value. From-SVN: r131573
