I don't know much about GNAT's virtual arrays. However, as long as they
are intended for the access of data and not code, then I think the
current backend should work without -mdisable-indexing. This patch fixed
a lot of problems in this area:
2000-11-22 John David Anglin <dave@hiauly1.hia.nrc.ca>
* function.h (emit_status): Delete member regno_pointer_flag and
rename regno_pointer_flag_length to regno_pointer_align_length.
Delete define for REGNO_POINTER_FLAG.
* integrate.h (inline_remap): Delete member regno_pointer_flag.
Add member x_regno_reg_rtx.
* rtl.h (rtx_def): Use frame_related bit to indicate register is
a pointer in REG expressions. Define REG_POINTER macro.
* alias.c (find_base_value, find_base_term): Use REG_POINTER
instead of REGNO_POINTER_FLAG.
* combine.c (nonzero_bits, num_sign_bit_copies): Likewise.
* emit-rtl.c (gen_reg_rtx): Use regno_pointer_align_length instead
of regno_pointer_flag_length. Remove code which refers to
regno_pointer_flag.
(mark_reg_pointer): Use REG_POINTER.
(free_emit_status): Remove code which refers to regno_pointer_flag.
(init_emit, mark_emit_status): Likewise.
* flow.c (dump_flow_info): Likewise.
* function.c (preserve_temp_slots): Likewise.
* integrate.c (expand_inline_function, copy_rtx_and_substitute):
Use x_regno_reg_rtx instead of regno_pointer_flag for function
pointer determination in map.
* loop.c (strength_reduce, maybe_eliminate_biv_1): Use REG_POINTER.
* predict.c (estimate_probability): Likewise.
* regclass.c (record_address_regs, reg_scan_mark_refs): Likewise.
* unroll.c (unroll_loop): Use x_regno_reg_rtx instead of
regno_pointer_flag for function pointer determination in map.
* convex.h (RTX_COSTS): Don't test regno_pointer_flag and use
REG_POINTER.
* pa.c (hppa_legitimize_address, emit_move_sequence, basereg_operand):
Use REG_POINTER.
(restore_unscaled_index_insn_codes): Revise comment.
Has the PA indexing situation been reviewed since the above patch was
installed?
