(_bfd_sparc_elf_link_hash_table_create): Don't initialize build_plt_entry here. (create_got_section): Initialize sgotplt for VxWorks. (_bfd_sparc_elf_create_dynamic_sections): Initialize build_plt_entry, plt_header_size and plt_entry_size, with new VxWorks-specific settings. Call elf_vxworks_create_dynamic_sections for VxWorks. (allocate_dynrelocs): Use plt_header_size and plt_entry_size. Allocate room for .got.plt and .rela.plt.unloaded entries on VxWorks. (_bfd_sparc_elf_size_dynamic_sections): Don't allocate a nop in .plt for VxWorks. Check for the .got.plt section. (sparc_vxworks_build_plt_entry): New function. (_bfd_sparc_elf_finish_dynamic_symbol): Add handling of VxWorks PLTs. Don't make _GLOBAL_OFFSET_TABLE_ and _PROCEDURE_LINKAGE_TABLE_ absolute on VxWorks. (sparc32_finish_dyn): Add special handling for DT_RELASZ and DT_PLTGOT on VxWorks. (sparc_vxworks_finish_exec_plt): New. (sparc_vxworks_finish_shared_plt): New. (_bfd_sparc_elf_finish_dynamic_sections): Call them. Use plt_header_size and plt_entry_size. * elfxx-sparc.h (_bfd_sparc_elf_link_hash_table): Add is_vxworks, srelplt2, sgotplt, plt_header_size and plt_entry_size fields. * Makefile.am (elfxx-sparc.lo): Depend on elf-vxworks.h. (elf32-sparc.lo): Likewise. * Makefile.in: Regenerate. * targets.c (bfd_elf32_sparc_vxworks_vec): Declare. (_bfd_target_vector): Add a pointer to it. gas/ * config/tc-sparc.c (sparc_target_format): Handle TE_VXWORKS. (GOTT_BASE, GOTT_INDEX): New. (tc_gen_reloc): Don't alter relocations against GOTT_BASE and GOTT_INDEX when generating VxWorks PIC. * configure.tgt (sparc*-*-vxworks*): Remove this special case; use the generic *-*-vxworks* stanza instead. gas/testsuite/ * gas/sparc/vxworks-pic.s, gas/sparc/vxworks-pic.d: New test. * gas/sparc/sparc.exp: Run it. Remove sparc*-*-vxworks* XFAILs. ld/ * configure.tgt (sparc*-*-vxworks*): New stanza. * emulparams/elf32_sparc_vxworks.sh: New file. * Makefile.am (ALL_EMULATIONS): Add eelf32_sparc_vxworks.o. (eelf32_sparc_vxworks.c): New rule. * Makefile.in: Regenerate. ld/testsuite/ * ld-sparc/vxworks1.dd, ld-sparc/vxworks1.ld, ld-sparc/vxworks1-lib.dd, * ld-sparc/vxworks1-lib.nd, ld-sparc/vxworks1-lib.rd, * ld-sparc/vxworks1-lib.s, ld-sparc/vxworks1.rd, ld-sparc/vxworks1.s, * ld-sparc/vxworks1-static.d, ld-sparc/vxworks2.s, * ld-sparc/vxworks2.sd, ld-sparc/vxworks2-static.sd: New tests. * ld-sparc/sparc.exp: Run them. --- bfd/elf32-sparc.c | 66 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) (limited to 'bfd/elf32-sparc.c') diff --git a/bfd/elf32-sparc.c b/bfd/elf32-sparc.c index 031b3034a8..3bfb38a3d4 100644 --- a/bfd/elf32-sparc.c +++ b/bfd/elf32-sparc.c @@ -26,6 +26,7 @@ #include "elf/sparc.h" #include "opcode/sparc.h" #include "elfxx-sparc.h" +#include "elf-vxworks.h" /* Support for core dump NOTE sections. */ @@ -215,3 +216,68 @@ elf32_sparc_reloc_type_class (const Elf_Internal_Rela *rela) #define elf_backend_rela_normal 1 #include "elf32-target.h" + +/* A wrapper around _bfd_sparc_elf_link_hash_table_create that identifies + the target system as VxWorks. */ + +static struct bfd_link_hash_table * +elf32_sparc_vxworks_link_hash_table_create (bfd *abfd) +{ + struct bfd_link_hash_table *ret; + + ret = _bfd_sparc_elf_link_hash_table_create (abfd); + if (ret) + { + struct _bfd_sparc_elf_link_hash_table *htab; + + htab = (struct _bfd_sparc_elf_link_hash_table *) ret; + htab->is_vxworks = 1; + } + return ret; +} + +/* A final_write_processing hook that does both the SPARC- and VxWorks- + specific handling. */ + +static void +elf32_sparc_vxworks_final_write_processing (bfd *abfd, bfd_boolean linker) +{ + elf32_sparc_final_write_processing (abfd, linker); + elf_vxworks_final_write_processing (abfd, linker); +} + +#undef TARGET_BIG_SYM +#define TARGET_BIG_SYM bfd_elf32_sparc_vxworks_vec +#undef TARGET_BIG_NAME +#define TARGET_BIG_NAME "elf32-sparc-vxworks" + +#undef ELF_MINPAGESIZE +#define ELF_MINPAGESIZE 0x1000 + +#undef bfd_elf32_bfd_link_hash_table_create +#define bfd_elf32_bfd_link_hash_table_create \ + elf32_sparc_vxworks_link_hash_table_create + +#undef elf_backend_want_got_plt +#define elf_backend_want_got_plt 1 +#undef elf_backend_plt_readonly +#define elf_backend_plt_readonly 1 +#undef elf_backend_got_header_size +#define elf_backend_got_header_size 12 +#undef elf_backend_add_symbol_hook +#define elf_backend_add_symbol_hook \ + elf_vxworks_add_symbol_hook +#undef elf_backend_link_output_symbol_hook +#define elf_backend_link_output_symbol_hook \ + elf_vxworks_link_output_symbol_hook +#undef elf_backend_emit_relocs +#define elf_backend_emit_relocs \ + elf_vxworks_emit_relocs +#undef elf_backend_final_write_processing +#define elf_backend_final_write_processing \ + elf32_sparc_vxworks_final_write_processing + +#undef elf32_bed +#define elf32_bed sparc_elf_vxworks_bed + +#include "elf32-target.h" -- cgit v1.2.1
