* defaults.h (ASM_PREFERRED_EH_DATA_FORMAT): New.
* dwarf2asm.c (dw2_force_const_mem, dw2_output_indirect_constant_1,
dw2_output_indirect_constants, dw2_asm_output_encoded_addr_rtx): New.
* dwarf2asm.h (dw2_asm_output_encoded_addr_rtx): Prototype.
(dw2_output_indirect_constants): Prototype.
* dwarf2out.c (dwarf2out_begin_prologue): Generate
current_function_func_begin_label if we'll need it for EH. Exit
early for IA64_UNWIND_INFO.
* except.c: Get DW_EH_PE_* defines from dwarf2.h.
(eh_data_format_name): Update for indirect references.
(output_function_exception_table): Care for IA64_UNWIND_INFO.
Handle ASM_PREFERRED_EH_DATA_FORMAT.
* except.h (MUST_USE_SJLJ_EXCEPTIONS): IA64_UNWIND_INFO needn't
define HAVE_eh_return etc.
* final.c (final_start_function): Always call dwarf2out_begin_prologue.
(final_end_function): Don't call output_function_exception_table.
* toplev.c (compile_file): Call dw2_output_indirect_constants.
(rest_of_compilation): Invoke output_function_exception_table
for ia64 before assemble_end_function.
* tm.texi (ASM_PREFERRED_EH_DATA_FORMAT): Document.
(ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX): Document.
* unwind-dw2.c (_Unwind_GetTextRelBase, _Unwind_GetDataRelBase): New.
* unwind.h: Declare them.
* libgcc-std.ver: Export them.
* unwind-pe.h: New file.
* config/alpha/elf.h (ASM_PREFERRED_EH_DATA_FORMAT): New.
* config/ia64/fde-glibc.c: Use "struct unw_table_entry"
instead of "fde".
(find_fde_for_dso): Extract DT_PLTGOT.
(_Unwind_FindTableEntry): Rename from __ia64_find_fde; return
the segment and gp as well.
* config/ia64/frame-ia64.c: Remove file.
* config/ia64/frame-ia64.h: Remove file.
* config/ia64/unwind-ia64.c: New file.
* config/ia64/unwind-ia64.h: New file.
* config/ia64/ia64.h (ASM_OUTPUT_EH_CHAR): Remove.
(ASM_OUTPUT_EH_SHORT, ASM_OUTPUT_EH_INT): Remove.
(ASM_OUTPUT_EH_DOUBLE_INT): Remove.
(ASM_PREFERRED_EH_DATA_FORMAT): New.
(ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX): New.
(IA64_UNWIND_INFO): Re-enable.
(HANDLER_SECTION): Remove.
(EH_RETURN_DATA_REGNO): New.
* config/ia64/ia64.md (exception_receiver): Remove.
* config/ia64/t-glibc (LIB2ADDEH): Re-enable.
* config/ia64/t-ia64 (LIB2ADDEH): Re-enable.
