gcc/ * recog.c (general_operand): Return true/false instead of 1/0. (register_operand): Ditto. (immediate_operand): Ditto. (const_int_operand): Ditto. (const_scalar_int_operand): Ditto. (const_double_operand): Ditto. (push_operand): Ditto. (pop_operand): Ditto. (memory_operand): Ditto. (indirect_operand): Ditto. Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}. Pushed to master. Uros.
