2004-07-06 Nick Clifton <nickc@redhat.com>
* config.bfd: Add sh-symbian-elf target.
* configure.in: Add bfd_elf32_shl_symbian_vec.
* configure: Regenerate.
* elf-bfd.h (struct elf_backend_data): Add new field
'check_directives'.
* elflink.c (elf_link_add_object_symbols): Invoke the
check_directives function, if defined.
* elfxx-target.h: Provide a default, NULL definition for
check_directives.
* targets.c: Add bfd_elf32_shl_symbian_vec.
* elf32-sh.c (sh_elf_swap_insns): Protect against unnecessary
definition.
(elf32_shlin_grok_prstatus, elf32_shlib_grok_psinfo,
* sh_elf_get_flags_from_mach, sh_elf_find_flags): Likewise.
(TARGET_BIG_SYM, TARGET_LITTLE_SYM): Only define if they have
not already been defined.
* elf32-sh64.c: Use SH_TARGET_ALREADY_DEFINED.
* sh-symbian.c: New file. Provide functions to support the
* sh-symbian-elf target.
* Makefile.am: Add elf32-sh-symbian.c
* Makefile.in: Regenerate.
2004-07-05 Andrew Stubbs <andrew.stubbs@superh.com>
* elf32-sh.c: Include ../opcodes/sh-opc.h .

# Unusual variables checked by this code:
# NOP - four byte opcode for no-op (defaults to 0)
# DATA_ADDR - if end-of-text-plus-one-page isn't right for data start
# INITIAL_READONLY_SECTIONS - at start of text segment
# OTHER_READONLY_SECTIONS - other than .text .init .rodata ...
# (e.g., .PARISC.milli)
# OTHER_TEXT_SECTIONS - these get put in .text when relocating
# OTHER_READWRITE_SECTIONS - other than .data .bss .ctors .sdata ...
# (e.g., .PARISC.global)
# OTHER_BSS_SECTIONS - other than .bss .sbss ...
# OTHER_SECTIONS - at the end
# EXECUTABLE_SYMBOLS - symbols that must be defined for an
# executable (e.g., _DYNAMIC_LINK)
# TEXT_START_SYMBOLS - symbols that appear at the start of the
# .text section.
# DATA_START_SYMBOLS - symbols that appear at the start of the
# .data section.
# OTHER_GOT_SYMBOLS - symbols defined just before .got.
# OTHER_GOT_SECTIONS - sections just after .got.
# OTHER_SDATA_SECTIONS - sections just after .sdata.
# OTHER_BSS_SYMBOLS - symbols that appear at the start of the
# .bss section besides __bss_start.
# DATA_PLT - .plt should be in data segment, not text segment.
# BSS_PLT - .plt should be in bss segment
# TEXT_DYNAMIC - .dynamic in text segment, not data segment.
# EMBEDDED - whether this is for an embedded system.
# SHLIB_TEXT_START_ADDR - if set, add to SIZEOF_HEADERS to set
# start address of shared library.
# INPUT_FILES - INPUT command of files to always include
# WRITABLE_RODATA - if set, the .rodata section should be writable
# INIT_START, INIT_END - statements just before and just after
# combination of .init sections.
# FINI_START, FINI_END - statements just before and just after
# combination of .fini sections.
# STACK_ADDR - start of a .stack section.
# OTHER_END_SYMBOLS - symbols to place right at the end of the script.
#
# When adding sections, do note that the names of some sections are used
# when specifying the start address of the next.
#
# Many sections come in three flavours. There is the 'real' section,
# like ".data". Then there are the per-procedure or per-variable
# 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.
