doc/bfdint.texi and comments in the aout and som code about this
function are just wrong, and its name is not very apt. Better would
be _bfd_mostly_destroy, and we certainly should not be saying anything
about the possibility of later recreating anything lost by this
function. What's more, if _bfd_free_cached_info is called when
creating an archive map to reduce memory usage by throwing away
symbols, the target _close_and_cleanup function won't have access to
tdata or section bfd_user_data to tidy memory. This means most of the
target _close_and_cleanup function won't do anything, and therefore
sometimes will result in memory leaks.
This patch fixes the documentation problems and moves most of the
target _close_and_cleanup code to target _bfd_free_cached_info.
Another notable change is that bfd_generic_bfd_free_cached_info is now
defined as _bfd_free_cached_info rather than _bfd_bool_bfd_true,
ie. the default now frees objalloc memory.

The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

static variables like mips_hi16_list are nasty for applications using
bfd. It is possible when opening and closing bfds with mis-matched
hi/lo relocs to leave a stale section pointer on the list. That can
cause a segfault if multiple bfds are being processed.
Tidying the list when closing is sufficient to stop this happening
(and fixes small memory leaks). This patch goes further and moves
mips_hi16_list to where it belongs in the bfd tdata.

Access to section data during relocation processing should be bounds
checked, as it is in bfd_perform_relocation. bfd_perform_relocation
does these checks after any special_function is called. So a reloc
special_function needs to do its own bounds checking before accessing
section data. This patch adds many such checks to the mips backend.
Checking mips relocs is not without some difficulty. See the comment
in _bfd_mips_reloc_offset_in_range. In a multitple reloc sequence
applied to the same location, relocs that may appear somewhere other
than the last one of the sequence need to be treated specially since
they apply to the addend for the next relocation rather than the
section contents. If the addend is in the section then it needs to be
checked but not when the addend is in the reloc. check_inplace
handles this situation. _bfd_mips_reloc_offset_in_range with
check_shuffle handles the case where contents are shuffled before
applying the relocation.

bfd_find_nearest_line_with_alt functions like bfd_find_nearest_line with
the addition of a parameter for specifying the filename of a supplementary
debug file such as one referenced by .gnu_debugaltlink or .debug_sup.
This patch focuses on implementing bfd_find_nearest_line_with_alt
support for ELF/DWARF2 .gnu_debugaltlink. For other targets this
function simply sets the invalid_operation bfd_error.

MIPS should not be using BFD_RELOC_16 for its R_MIPS_16 relocation,
since R_MIPS_16 specifies a 16-bit field in a 32-bit word.
BFD_RELOC_16, emitted by generic code to handle fixups on 16-bit data
directives, expects fixups to operate on the whole of a 16-bit word.
This patch corrects the problem by using BFD_RELOC_MIPS_16, a new bfd
reloc that is used to generate R_MIPS_16. BFD_RELOC_16 is handled in
md_apply_fix for cases where the fixup can be applied at assembly
time. Like BFD_RELOC_8, BFD_RELOC_16 now has no corresponding object
file relocation, and thus .half, .hword, .short and .dc.w must be
resolved at assembly time. BFD_RELOC_MIPS_REL16 is removed by this
patch since it isn't used.

This changes the HOWTO macro to encode the howto.size field from a
value given in bytes. This of course requires editing all target
uses of HOWTO, a major pain, but makes it a little nicer to specify
new target HOWTOs. Object files before/after this patch are
unchanged in .data and .rodata.

Correct ELF linker code so as to set the `sh_info' value of the static
symbol table section according to the section symbols vs other symbols
split where required by the selection of the IRIX compatibility mode for
MIPS target. Add a `elf_backend_elfsym_local_is_section' hook for that
purpose, returning TRUE if it is only STB_LOCAL/STT_SECTION symbols that
are to be considered local for the purpose of this split rather than all
STB_LOCAL symbols.
We do it already in generic ELF code, and have done it since 1993, with
the `elf_backend_sym_is_global' hook, affecting GAS and `objcopy', so
these tools produce correct ELF output in the IRIX compatibility mode,
however if such output is fed as input to `ld -r', then the linker's
output is no longer valid for that mode. The relevant changes to
generic ELF code are:

(split across two GIT commits likely due to repository conversion
peculiarities).
The `elf_backend_sym_is_global' hook however operates on BFD rather than
ELF symbols, making it unsuitable for the ELF linker as the linker does
not convert any symbol tables processed into the BFD format. Converting
the hook to operate on ELF symbols would in principle be possible, but
it would still require a considerable rewrite of `bfd_elf_final_link' to
adapt to the interface.
Therefore, especially given that no new use for the IRIX compatibility
mode is expected, minimize changes made to the ELF linker code and just
add an entirely new hook, and wire it in the o32 and n32 MIPS backends
accordingly; the n64 backend never uses the IRIX compatibility mode.
Since we have no coverage here at all add suitable GAS, LD and `objcopy'
test cases to the relevant testsuites to keep these tools consistently
verified.

We have an issue in the MIPS backend, with the handling of undefined
hidden and internal weak symbols. References to such symbols are
supposed to resolve to 0 according to the ELF gABI[1]:
"Unresolved weak symbols have a zero value."
and the 64-bit MIPS psABI[2]:
"If a symbol with one of these [hidden or internal] attributes has no
definition within the executable/DSO being linked, then it must be
resolved to allocated space if common, resolved to zero if weak, or an
error reported otherwise."
however if a GOT relocation is used, then a local GOT entry is created
and used to satisfy the reference. Such an entry is then (in DSO and
PIE binaries) subject to the usual load-time relocation, which means a
non-zero value will be returned if the base address is non-zero. This
will defeat the usual run-time sequence like:
void a (void) __attribute__ ((visibility ("hidden"), weak));
void
x (void)
{
if (a)
a ();
}
This can be reproduced with this simple code:
$ cat libtest.c
extern int a __attribute__ ((visibility ("hidden"), weak));
int *
x (void)
{
return &a;
}
$ cat test.c
int *x (void);
int
main (void)
{
printf ("a: %p\n", x ());
return 0;
}
$ gcc -shared -fPIC -o libtest.so libtest.c
$ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so
$ ./test
a: 0x77184000
$
The usual approach targets take is making all the steps required to
assign a GOT entry for the symbol referred, and then leave its contents
at zero with no dynamic relocation attached, therefore ensuring that the
value does not change at load time. However this is not going to work
with the implicitly relocated GOT the MIPS psABI specifies[3]:
"The dynamic linker relocates the global offset table by first adding
the difference between the base where the shared object is loaded and
the value of the dynamic tag DT_MIPS_BASE_ADDRESS to all local global
offset table entries."
and we cannot therefore use the local GOT part.
And we cannot offhand use the global part either, as the symbol would
then have to be exported and possibly wrongly preempt symbols in other
modules involved in the dynamic load, because as per the ELF gABI[1] we
are not allowed to enter a hidden or internal symbol into the dynamic
symbol table (and then use its associated GOT entry):
"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
and:
"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
So we have to choose something else.
Our choice is further limited by the need for the reference associated
with the GOT relocation to stay within the signed 16-bit limit from the
GOT pointer base register, while being compliant with the ELF gABI and
the MIPS psABI. However as Alan Modra has observed[4] one possibility
is to edit (relax) the code such that the GOT reference is removed
altogether.
Based on these observations then modify MIPS BFD linker backend code to:
1. Interpret code associated with GOT relocations and relax the usual LW
or LD instructions into a corresponding immediate load operation that
places the value of 0 in the intended register, while leaving the GOT
entry allocated and initialized as usually.
2. Leave any other instructions associated with GOT relocations in place
and instead redirect the reference to a global GOT entry associated
with a special `__gnu_absolute_zero' symbol created for this purpose,
whose value is 0, SHN_ABS section marks it absolute, binding is
global and export class protected, ensuring that the locally provided
value is always used at load time, and that the value is not
relocated by the dynamic loader.
3. Adjust any high-part GOT relocation used, typically associated with
a LUI instruction, accordingly, so that run-time consistency is
maintained, either by resolving to the original entry if the
instruction associated with the corresponding low-part GOT relocation
has been relaxed to an immediate load (in which case the value loaded
with LUI will be overwritten), or by also redirecting the reference
to `__gnu_absolute_zero' to complete the GOT access sequence if that
symbol has been used.
4. Add a target `elf_backend_hide_symbol' hook, for the three MIPS ABIs,
which prevents the `__gnu_absolute_zero' symbol from being forced
local, to ensure that the redirection works and the symbol remains
global/protected with existing linker scripts unchanged.
5. Observing the issue with handling SHN_ABS symbols in the GNU dynamic
loader, covered by glibc PR 19818, set the EI_ABIVERSION field in the
ELF file header produced to 4 (ABI_ABSOLUTE) if `__gnu_absolute_zero'
symbol has been produced and the target configured indicates the GNU
operating system, so that broken versions of the GNU dynamic loader
gracefully reject the file in loading rather than going astray. Keep
EI_ABIVERSION at the original value for other operating systems or if
no `__gnu_absolute_zero' symbol has been made.
The name of the special `__gnu_absolute_zero' has no meaning other than
how a human reader can interpret it, as it is ignored in dynamic loading
in the handling of the scenarios concerned. This is because the symbol
resolves locally, and it's only the symbol's attributes that matter so
that the associated GOT entry remains unchanged at load time.
Therefore the name is somewhat arbitrary, observing however the need to
use the name space reserved for the system so that it does not conflict
with a possible user symbol, and hence the leading underscore, and also
the `gnu' infix to denote a GNU feature. Other implementations wishing
to address the problem in a similar way may choose a different name and
have the solution still work, possibly with a mixture of modules used in
a dynamic having symbols of different names provided, which will however
not interact with each other due to the protected export class.
The symbol can be referred explicitly, however the name is an internal
implementation detail rather than a part of the ABI, and therefore no
specific semantics is guaranteed.
One limitation of this change is that if `__gnu_absolute_zero' has been
already defined, then we do not wipe the old definition and all kinds of
odd behavior can result. This is however like with other symbols we
internally define, such as `_GLOBAL_OFFSET_TABLE_' or `__rld_map', and
therefore left as a possible future enhancement.
As an optimization the relaxation of LW and LD instructions to a load of
immediate zero is always made, even SVR4 PIC code for code that will end
up in a regular (non-PIE) executable, because there is a cache advantage
with the avoidance of a load from the GOT, even if it is otherwise
guaranteed to remain zero. It does not reliably happen though, due to a
symbol exportation issue affecting executables, covered by PR ld/21805.
One existing test case needs to be updated, as it triggers relaxation
introduced with this change and consequently linker output does not
match expectations anymore. As we want to keep the original issue
covered with the test case modify it then to use the LWL instruction in
place of LW, and adjust the output expected accordingly.

On MIPS o32, n32 and n64 platforms, PID information was not
correctly propagated from core dump file to internal GDB
structures. This patch fixes that behavior.
A correct PID is needed by `libthread_db' library supplied with
glibc repository revisions before commit c579f48edba8 ("Remove
cached PID/TID in clone") or released versions before 2.25 for
GDB to fetch value of TLS variable from core file.

Fix a bug in MIPS n32 ELF object file generation and make such objects
consistent with the n32 BFD requested, by presetting the EF_MIPS_ABI2
flag in the `e_flags' member of the newly created ELF file header, as it
is this flag that tells n32 objects apart from o32 objects.
This flag will then stay set through to output file generation for
writers such as GAS or GDB's `generate-core-file' command. Readers will
overwrite the whole of `e_flags' along with the rest of the ELF file
header in `elf_swap_ehdr_in' and then verify in `mips_elf_n32_object_p'
that the flag is still set before accepting an input file as an n32
object.
The issue was discovered with GDB's `generate-core-file' command making
o32 core files out of n32 debuggees.

Remove separate original NewABI JALR relocation handling, introduced

symbol"), <https://sourceware.org/ml/binutils/2003-03/msg00394.html>,
and only used by LD with the `--relax' option specified, and rely solely
on `mips_elf_perform_relocation' code, which has been introduced with
commit 1367d393bb74 ("On the RM9000 convert jal to bal if in range"),
<https://www.sourceware.org/ml/binutils/2004-12/msg00088.html> and since

Commit ec93045b and cd21f5da introduced a large number of tic4x and
tic54x regressions, due to the new checks being wrong for targets
with octets_per_byte != 1. To fix that I introduced a new
bfd_get_section_limit_octets and performed the check on octets rather
than byte adresses, reducing the number of bfd_octets_per_byte calls.
bfd_octets_per_byte is rather expensive..
I then wondered why the same bfd_reloc_outofrange check added to
bfd_perform_relocation wasn't also added to bfd_install_relocation.
The two functions are virtually identical and ought to remain that
way. However, adding the same check to bfd_install_relocation
resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF
targets, including x64_64-linux. The reason being that eh-group.o
