Since all callers either passed 0 or 1 for clear_ret, define bit 0 in the flags for use as clear_ret. Reserve bits 1, 2 and 3 for use by MI code for possible (but unlikely) future use. The remaining bits are for use by MD code. This change is triggered by a need on ia64 to have another knob for get_mcontext(). |
