ARM BPABI PT_DYNAMIC segment


This patch implements changes relating to the ARM BPABI PT_DYNAMIC
segment.  There should be a PT_DYNAMIC segment, even though the
.dynamic section is not marked SEC_ALLOC.  Furthermore, DT_HASH,
DT_STRTAB, etc. need to use file offsets, not VMA addresses.  I had to
create a new linker script so as to get the VMA address for .hash,
etc., set to zero in the ELF output file, as required, since these
sections are not loaded at runtime under the BPABI.

OK?

	* elf-bfd.h (_bfd_elf_make_dynamic_segment): Declare it.
	* elf.c (_bfd_elf_make_dynamic_segment): New function, split out
	from ...
	(map_sections_to_segments): ... here.  Use it.  Assign a file
	position to the .dynamic section if it is not loadable, but part
	of the PT_DYNAMIC segment.
	* elf32-arm.h (elf32_arm_finish_dynamic_sections): Use file
	offsets, not VMAs, for the BPABI.  Do not fill in the header in
	the .got.plt section for the BPABI.
	* elfarm-nabi.c (elf32_arm_symbian_modify_segment_map): Add a
	PT_DYNAMIC segment.
	(elf_backend_want_got_plt): Define to zero for Symbian OS.

2004-09-03  Mark Mitchell  <mark@codesourcery.com>

	* emulparams/armsymbian.sh: Use armbpabi script.
	* scripttempl/armbpabi.sc: New script.

+ #  Many sections come in three flavours.  There is the 'real' section,

+ #  sections, generated by -ffunction-sections and -fdata-sections in GCC,
+ #  and useful for --gc-sections, which for a variable "foo" might be
+ #  ".data.foo".  Then there are the linkonce sections, for which the linker
+ #  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
+ #  The exact correspondences are:
+ #
+ #  Section	Linkonce section
+ #  .text	.gnu.linkonce.t.foo
+ #  .rodata	.gnu.linkonce.r.foo
+ #  .data	.gnu.linkonce.d.foo
+ #  .bss		.gnu.linkonce.b.foo
+ #  .sdata	.gnu.linkonce.s.foo
+ #  .sbss	.gnu.linkonce.sb.foo
+ #  .sdata2	.gnu.linkonce.s2.foo
+ #  .sbss2	.gnu.linkonce.sb2.foo
+ #  .debug_info	.gnu.linkonce.wi.foo
+ #  .tdata	.gnu.linkonce.td.foo
+ #  .tbss	.gnu.linkonce.tb.foo
+ #
+ #  Each of these can also have corresponding .rel.* and .rela.* sections.
