include/coff/
* internal.h (C_AIX_WEAKEXT): New macro. (C_WEAKEXT): Use the GNU definition in the generic part of the file, and conditionally reset it to C_AIX_WEAKEXT in the XCOFF part of the file. (CSECT_SYM_P): New macro. * xcoff.h (L_WEAK): Define. (EXTERN_SYM_P): New macro. bfd/ * coffcode.h (coff_pointerize_aux_hook): Update CSECT_SYM_P to check whether a symbol has csect information. (coff_print_aux): Likewise. * coff-rs6000.c (_bfd_xcoff_swap_aux_in): Handle auxillary csect information for C_AIX_WEAKEXT too. (_bfd_xcoff_swap_aux_out): Likewise. (xcoff_reloc_type_br): Handle defweak symbols too. * coff64-rs6000.c (_bfd_xcoff64_swap_aux_in): Handle auxillary csect information for C_AIX_WEAKEXT too. (_bfd_xcoff64_swap_aux_out): Likewise. (xcoff64_reloc_type_br): Handle defweak symbols too. * coffgen.c (coff_print_symbol): Handle auxillary function information for C_AIX_WEAKEXT too. * xcofflink.c (_bfd_xcoff_canonicalize_dynamic_symtab): Set BSF_WEAK instead of BSF_GLOBAL if the L_WEAK flag is set. (xcoff_dynamic_definition_p): New function. (xcoff_link_add_dynamic_symbols): Use it to decide whether ldsym defines h. Don't change h if ldsym isn't the definition. Otherwise, always take the symbol class from the ldsym. Use weak bfd symbol types for weak ldsyms. (xcoff_link_add_symbols): Use CSECT_SYM_P and EXTERN_SYM_P. Fix the check for whether a definition is from a shared object. Allow redefinitions of weak symbols. (xcoff_link_check_ar_symbols): Use EXTERN_SYM_P. (xcoff_keep_symbol_p): Likewise. (bfd_xcoff_size_dynamic_sections): Use CSECT_SYM_P. (xcoff_link_input_bfd): Use CSECT_SYM_P and EXTERN_SYM_P. Add .loader entries for C_AIX_WEAKEXT as well as C_EXT symbols, but mark them as L_WEAK. (xcoff_write_global_symbol): Treat weak symbols as C_AIX_WEAKEXT instead of C_EXT if C_AIX_WEAKEXT == C_WEAKEXT. gas/ * config/tc-ppc.c (ppc_frob_symbol): Add csect information for C_AIX_WEAKEXT too. ld/testsuite/ * ld-powerpc/aix-glink-2a.s, ld-powerpc/aix-glink-2a.ex, ld-powerpc/aix-glink-2b.s, ld-powerpc/aix-glink-2c.s, ld-powerpc/aix-glink-2c.ex, ld-powerpc/aix-glink-2d.s, ld-powerpc/aix-glink-2-32.dd, ld-powerpc/aix-glink-2-64.dd, ld-powerpc/aix-weak-1a.s, ld-powerpc/aix-weak-1b.s, ld-powerpc/aix-weak-1-rel.hd, ld-powerpc/aix-weak-1-rel.nd, ld-powerpc/aix-weak-1-dso.hd, ld-powerpc/aix-weak-1-dso.nd, ld-powerpc/aix-weak-1-dso.dnd, ld-powerpc/aix-weak-1.ex, ld-powerpc/aix-weak-2a.s, ld-powerpc/aix-weak-2a.ex, ld-powerpc/aix-weak-2a.nd, ld-powerpc/aix-weak-2b.s, ld-powerpc/aix-weak-2b.nd, ld-powerpc/aix-weak-2c.s, ld-powerpc/aix-weak-2c.ex, ld-powerpc/aix-weak-2c.nd, ld-powerpc/aix-weak-2c.od, ld-powerpc/aix-weak-3a.s, ld-powerpc/aix-weak-3a.ex, ld-powerpc/aix-weak-3b.s, ld-powerpc/aix-weak-3b.ex, ld-powerpc/aix-weak-3-32.d, ld-powerpc/aix-weak-3-32.dd, ld-powerpc/aix-weak-3-64.d, ld-powerpc/aix-weak-3-64.dd: New tests. * ld-powerpc/aix52.exp: Run them. Replace tmp/aix-* with tmp/aix64-* in 64-bit ld options.
