darling-gdb/bfd/elf-hppa.h
Jeff Law 1bf425384c 2002-02-26 John David Anglin <dave@hiauly1.hia.nrc.ca> 
* bfd/elf-hppa.h (elf_hppa_is_dynamic_loader_symbol): New function.
	(elf_hppa_relocate_section): Ignore undefined dynamic loader symbols.
	(elf_hppa_final_link_relocate): Correct relocations for indirect
	references to local data through the DLT.  Fix .opd creation for
	local symbols using R_PARISC_LTOFF_FPTR32 and R_PARISC_FPTR64
	relocations.  Use e_lsel selector for R_PARISC_DLTIND21L,
	R_PARISC_LTOFF_FPTR21L and R_PARISC_LTOFF_TP21L as per
	"Processor-Specific ELF for PA_RISC, Version 1.43" document.
	Similarly, use e_rsel for DLT and LTOFF 'R' relocations.
	* bfd/elf32-hppa.c (final_link_relocate): Revise relocation selectors
	as per "Processor-Specific ELF for PA_RISC, Version 1.43" document.
