Replace occurrences of "_raw_size" and "_cooked_size" in most places

calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use

Replace occurrences of "_raw_size" and "_cooked_size" in most places

calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

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
|
2003-06-25 08:40:27 +02:00
|
|
|
necessary, and (if using Rela relocs and generating a relocatable
|
2002-07-17 16:15:52 +02:00
|
|
|
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).
|
|
|
|
|
2003-06-25 08:40:27 +02:00
|
|
|
When generating relocatable output, this function must handle
|
2002-07-17 16:15:52 +02:00
|
|
|
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. */

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead. What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".
This patch removes the status return on the callbacks that always
return true. I kept the return status for "notice" because that one
does happen to need to return "out of memory".

Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead. What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".
This patch removes the status return on the callbacks that always
return true. I kept the return status for "notice" because that one
does happen to need to return "out of memory".

This renames the bfd targets to <cpu>_<format>_<other>_<endian>_vec.
So for example, bfd_elf32_ntradlittlemips_vec becomes
mips_elf32_ntrad_le_vec and hp300bsd_vec becomes m68k_aout_hp300bsd_vec.
