Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

/* Relocate an FR30 ELF section.
|
|
|
|
|
|
There is some attempt to make this function usable for many architectures,
|
|
|
|
|
|
both USE_REL and USE_RELA ['twould be nice if such a critter existed],
|
|
|
|
|
|
if only to serve as a learning tool.
|
|
|
|
|
|
|
|
|
|
|
|
The RELOCATE_SECTION function is called by the new ELF backend linker
|
|
|
|
|
|
to handle the relocations for a section.
|
|
|
|
|
|
|
|
|
|
|
|
The relocs are always passed as Rela structures; if the section
|
|
|
|
|
|
actually uses Rel structures, the r_addend field will always be
|
|
|
|
|
|
zero.
|
|
|
|
|
|
|
|
|
|
|
|
This function is responsible for adjusting the section contents as
|
|
|
|
|
|
necessary, and (if using Rela relocs and generating a relocateable
|
|
|
|
|
|
output file) adjusting the reloc addend as necessary.
|
|
|
|
|
|
|
|
|
|
|
|
This function does not have to worry about setting the reloc
|
|
|
|
|
|
address or the reloc symbol index.
|
|
|
|
|
|
|
|
|
|
|
|
LOCAL_SYMS is a pointer to the swapped in local symbols.
|
|
|
|
|
|
|
|
|
|
|
|
LOCAL_SECTIONS is an array giving the section in the input file
|
|
|
|
|
|
corresponding to the st_shndx field of each local symbol.
|
|
|
|
|
|
|
|
|
|
|
|
The global hash table entry for the global symbols can be found
|
|
|
|
|
|
via elf_sym_hashes (input_bfd).
|
|
|
|
|
|
|
|
|
|
|
|
When generating relocateable output, this function must handle
|
|
|
|
|
|
STB_LOCAL/STT_SECTION symbols specially. The output symbol is
|
|
|
|
|
|
going to be the section symbol corresponding to the output
|
|
|
|
|
|
section, which means that the addend must be adjusted
|
|
|
|
|
|
accordingly. */
