+ Favor 'weak' parameter in a_call_name of both thlcgmips and TCGMIPS. * make_simple_ref and a_loadaddr_ref_reg: require input references to be 'raw' (no refaddr=addr_pic, etc) and do not use GP as base/index. If it's not true, raise an internal error. When addr_pic_call16 or so needs to be generated, it must be done without calling the mentioned methods. * thlcgmips.a_call_name: generate PIC sequence for procedures declared as 'external', instead of 'cdecl', this is more correct because ABI has only one calling convention. - make_simple_ref_fpu removed, there's no reason to handle references to floating-point data in different way. - a_loadaddr_ref_cgpara override also removed, generic method does the job just well. - thlcgmips.a_call_ref and a_call_reg overrides removed because indirect calls are now always done using $t9. git-svn-id: trunk@23698 -
