f9c3e5871e * ld-shared: New directory, with new files to test generating ELF
shared libraries.
1994-10-27 21:33:10 +00:00
Ian Lance Taylor
b5bd927ce5 * lib/ld.exp (default_ld_compile): If the compilation worked, but
no object file was created, check to see if the compiler foolishly
	ignored the -o switch when compiling, and move the resulting
	object if it did.
1994-10-27 21:31:50 +00:00
Ian Lance Taylor
14cac507a8 * libelf.h (struct bfd_elf_section_data): Add field dynindx.
* elfcode.h (NAME(bfd_elf,size_dynamic_sections)): Don't finalize
	the .dynsym, .dynstr or .hash sections until after the backend
	size_dynamic_sections routine, so that it can add dynamic symbols
	if it wants to.
	* elf32-i386.c (elf_i386_adjust_dynamic_symbol): Don't define the
	symbol to be in the .plt section when generating a shared library
	if it is a defined symbol.
	* elf32-sparc.c (elf32_sparc_adjust_dynamic_symbol): Likewise.
	(elf32_sparc_size_dynamic_sections): When generating a shared
	library, allocate space for a dynamic symbol for each output
	section, storing the index in the dynindx field of the ELF section
	data.  Adjust the other dynindx fields to account for this.
	(elf32_sparc_adjust_dynindx): New static function.
	(elf32_sparc_relocate_section): When copying a reloc into a shared
	library, use the original addend as appropriate.  Convert an
	R_SPARC_32 reloc into an R_SPARC_RELATIVE reloc.  Use the dynamic
	symbol index of the output section, not the normal symbol index.
	(elf32_sparc_finish_dynamic_sections): Don't die if a section does
	not exist when setting the value of the dynamic tags.  Write out
	a dynamic symbol for each output section.

	(elf_link_add_object_symbols): Create dynamic sections based on
	dynamic_sections_created field, not dynobj field.  Don't bother to
	set dynobj.
	(elf_link_create_dynamic_sections): If dynamic sections were
	already created, don't do anything.  If dynobj is already set, use
	it; otherwise, set it to the bfd argument.  Don't initialize
	dynsymcount.  Only create dynstr if it does not exist.  Set
	dynamic_sections_created to true.
	(NAME(bfd_elf,size_dynamic_sections)): Skip most of this function
	if no dynamic objects were seen.

	(elf_i386_create_got_section): New static function.

	a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
	Only create the .rel.got section, and only make space for a reloc,
	for a global symbol or when generating a shared object.  For a
	R_386_PLT32 reloc, just set the	ELF_LINK_HASH_NEEDS_PLT flag.
	(elf_i386_adjust_dynamic_symbol): Rework initial assertion to
	permit ELF_LINK_HASH_NEEDS_PLT non dynamic symbols.  Create a
	procedure linkage table entry for such symbols.  But, if no
	dynamic objects were seen, never create a PLT entry.
	(elf_i386_size_dynamic_sections): If no dynamic objects were seen,
	skip most of this function, and force the size of the .rel.got
	section to zero.
	(elf_i386_relocate_section): For a R_386_GOT32 reloc against a global
	symbol when no dynamic object was seen, initialize the contents of

	create a R_386_RELATIVE reloc when generating a shared object.
	Treat a R_386_PLT32 reloc against a symbol for which we did not
	create a PLT entry as a R_386_PC32 reloc.

	entries and the PLT if we saw a dynamic object.
	* elf32-sparc.c (elf_sparc_howto_table): Fix R_SPARC_PC22 by
	setting rightshift to 10.  Fix R_SPARC_WPLT20 by setting
	rightshift to 2, size to 2, bitsize to 30, and dst_mask to
	0x3fffffff.
	(elf32_sparc_create_dynamic_sections): Don't set the size of the
	.plt section.  Call elf32_sparc_create_got_section rather than
	creating the .got section.
	(elf32_sparc_check_relocs): Call elf32_sparc_create_got_section if
	a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
	Only create the .rela.got section, and only make space for a
	reloc, for a global symbol or when generating a shared object.
	Set the alignment of the .rela.got section to 2.  For a
	R_SPARC_WPLT30 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
	(elf32_sparc_adjust_dynamic_symbol): Rework initial assertion to
	permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols.  Create a
	procedure linkage table for such symbols.  But, if no dynamic
	objects were seen, never create a PLT entry.  Initialize the size
	of the .plt section.
	(elf32_sparc_size_dynamic_sections): If no dynamic objects were
	seen, skip most of this function, and force the size of the
	.rela.got section to zero.  Strip empty reloc sections, and strip
	an empty .plt section.
	(elf32_sparc_relocate_section): For a GOT reloc against a global
	symbol when no dynamic object was seen, initialize the contents of
	the .got section.  For a GOT reloc against a local symbol, only
	create a R_SPARC_RELATIVE reloc when generating a shared object.
	Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
	create a PLT entry as a R_SPARC_WDISP30 reloc.
	(elf32_sparc_finish_dynamic_sections): Only fiddle with the
	dynamic entries and the PLT if we saw a dynamic object.
