2001-07-31PowerPC reorg and support for powerpc64-*-linux*.Daniel Berlin12-873/+1434
2001-07-31 Daniel Berlin <dan@cgsoftware.com> PowerPC reorg and support for powerpc64-*-linux*. Also fixes emitting of constants on 32 bit and 64 bit platforms. * config.gcc: powerpc64-*-linux* is a new target. Things that needed aix.h now also include xcoff.h * config/rs6000/rs6000.h: Split XCOFF specific stuff into xcoff.h. Move AIX specific stuff into aix.h. (ASM_LONG): Use DOUBLE_INT_ASM_OP if we are on a 64 bit target. (ASM_OUTPUT_DOUBLE_INT): Ditto. (TARGET_AIX): Renamed to TARGET_XCOFF, since the AIX ABI is used with more than just XCOFF now. (SET_ASM_OP): Remove, now defined where needed. (FUNCTION_PROLOGUE): New macro definition. (FUNCTION_EPILOGUE): New macro definition. (CONST_OK_FOR_LETTER_P): Change N to require that value is positive, too. (ASM_OPEN_PAREN, ASM_CLOSE_PAREN): New macro definition. (PREDICATE_CODES): Added exact_log2_cint_operand, reg_or_add_cint64_operand, reg_or_sub_cint64_operand. * config/rs6000/rs6000.c: #ifdef XCOFF debugging info stuff on XCOFF_DEBUGGING_INFO. Use DOUBLE_INT_ASM_OP where approriate. (rs6000_emit_set_long_const): New function. (rs6000_emit_set_const): New function. (reg_or_sub_cint64_operand): New function. (reg_or_add_cint64_operand): New function. (exact_log2_cint_operand): New function. * config/rs6000/rs6000.md: Fix emitting of constants. Fix patterns that were AIX ABI specific, but depended on !TARGET_ELF (instead of DEFAULT_ABI == ABI_AIX). * config/rs6000/xcoff.h: New file. * config/rs6000/linux64.h: New file. * config/rs6000/darwin.h: Copy needed AIX alignment definitions.

(do_build_assign_ref): Adjust. * search.c (lookup_field_r): Adjust. * typeck.c (build_component_ref): Adjust. The 3.0 ABI always has a vtable pointer at the start of every polymorphic class. * rtti.c (build_headof_sub): Remove. (build_headof): Adjust. (get_tinfo_decl_dynamic): No need to check flag_rtti here. Adjust. (create_real_tinfo_var): Explain why we need a hidden name. From-SVN: r44515
