It seems I had some misunderstanding about IA-64 model attribute. IA-64 actually does not have -mcmodel= options. And a code model only specifies where "the GOT and the local symbols" are, but our new attribute should apply for both local symbols and global symbols. So I don't think we should strongly bind the new attribute and -mcmodel. Maybe, __attribute__((addressing_model(got/pcrel32/pcrel64/abs32/abs64)) ? I think they are explicit enough (we can implement got and pc32 first, and adding the others when we implement other code models). -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
