This modifies _bfd_elf_free_cached_info to unmap/free section
contents. To do that we need to *not* free sections where contents
are bfd_alloc'd or point to constant strings or somesuch. I've chosen
to implement this be adding another flag to struct bfd_section,
"alloced" to say the section contents can't be freed. Most of the
patch is about setting that flag in many places.

This is another case where the proper object_id can be read from
elf_backend_data.
|
|
hash_table_id can be set from elf_backend_data, now that all targets
have matching ELF_TARGET_ID and hash_table_init target_id.
|
|
Any _new_section_hook that is not itself called from another
_new_section_hook will always see used_by_bfd NULL. Remove those
NULL checks in such hooks, and tidy code a little.

A previous patch made ld fail early on Thumb-only where branch_type is
ST_BRANCH_UNKNOWN.
However, this fails erroneously when the target is undefweak: in that
case the branch should be replaced by a branch to the next instruction
(or nop.w on thumb2). This patch accepts this case and restores the
previous behaviour in such cases.
This was reported by failures in the GCC testsuite, where we fail to
link executables because __deregister_frame_info is undefweak:
(__deregister_frame_info): Unknown destination type (ARM/Thumb) in ...crtbegin.o
crtbegin.o: in function `__do_global_dtors_aux':
crtstuff.c:(.text+0x52): dangerous relocation: unsupported relocation

We recently fixed a bug in libgcc
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115360)
where a symbol was missing a %function .type decoration.
This meant the linker would silently pick the wrong type of 'farcall
stub', involving Arm-mode instructions on Thumb-only CPUs.
This patch emits an error instead, and warns in some other cases, to
encourage users to add the missing '.type foo,%function' directive.
In practice: in arm_type_of_stub() we no longer try to infer which
stub to use if the destination is of unknown type and the CPU is
Thumb-only; so we won't lie to elf32_arm_size_stubs() which does not
check branch_type.
If branch_type is ST_BRANCH_TO_ARM but the CPU is Thumb-only, we now
convert it to ST_BRANCH_TO_THUMB only if the destination is of
absolute type. This is to support the case where the destination of
the branch is defined by the linker script (see thumb-b-lks-sym.s and
thumb-bl-lks-sym.s testcases for instance).
The motivating case is covered by the new farcall-missing-type
testcase, where we now emit an error message. We do not emit an error
when branch_type is ST_BRANCH_UNKNOWN and the CPU supports Arm-mode: a
lot of legacy code (e.g. newlib's crt0.S) lacks the corresponding
'.type foo, %function' directives and even a (too verbose) warning
could be perceived as a nuisance.
Existing testcases where such a warning would trigger:
arm-static-app.s (app_func, app_func2)
arm-rel32.s (foo)
arm-app.s (app_func)
rel32-reject.s () main)
fix-arm1176.s (func_to_branch_to)
but this list is not exhaustive.
For the sake of clarity, the patch replaces occurrences of
sym.st_target_internal = 0; with
sym.st_target_internal = ST_BRANCH_TO_ARM;
enum arm_st_branch_type is defined in include/elf/arm.h, and relies on
ST_BRANCH_TO_ARM==0, as sym.st_target_internal is also initialized to
0 in other target-independent parts of BFD code. (For instance,
swapping the ST_BRANCH_TO_ARM and ST_BRANCH_TO_THUMB entries in the
enum definition leads to 'interesting' results...)
Regarding the testsuite:
* new expected warning for thumb-b-lks-sym and thumb-bl-lks-sym
* new testcase farcall-missing-type to check the new error case
* attr-merge-arch-2b.s, branch-futures (and bfs-1.s) updated to avoid
a diagnostic
Tested on arm-eabi and arm-pe with no regression.

This largely mechanical patch is preparation for a followup patch.
For quite some time I've thought that it would be useful to call
elf_backend_size_dynamic_sections even when no dynamic objects are
seen by the linker. That's what this patch does, with some renaming.
There are no functional changes to the linker, just a move of the
dynobj test in bfd_elf_size_dynamic_sections to target backend
functions, replacing the asserts/aborts already there. No doubt some
of the current always_size_sections functions could be moved to
size_dynamic_sections but I haven't made that change.
Because both hooks are now always called, I have renamed
always_size_sections to early_size_sections and size_dynamic_sections
to late_size_sections. I condisdered calling late_size_sections plain
size_sections, since this is the usual target dynamic section sizing
hook, but decided that searching the sources for "size_sections" would
then hit early_size_sections and other functions.

Returning false from elf_backend_finish_dynamic_symbol will not result
in an error being printed unless bfd_error is set but will result in
the linker exiting with a non-zero status. If just bfd_error is set
then a generic "final link failed" will result, which doesn't help a
user much. So elf_backend_finish_dynamic_symbol should print its own
error message whenever returning false, or use BFD_ASSERT or abort to
print assertion failures for conditions that shouldn't occur.
This patch does that, and removes unnecessary "htab != NULL" tests in
elf_backend_finish_dynamic_symbol. Such tests aren't needed in a
function only called via elf_backend_data.

A number of backends want to return bfd_reloc_dangerous messaqes from
relocation special_function, and construct the message using asprintf.
Such messages are not freed anywhere, leading to small memory leaks
inside libbfd. To limit the leaks, I'd implemented a static buffer in
the ppc backends that was freed before use in asprintf output. This
patch extends that scheme to other backends using a shared static
buffer and goes further in freeing the buffer on any bfd_close.
The patch also fixes a few other cases where asprintf output was not
freed after use.

This is a fuzzing PR, with a testcase involving a SHF_ALLOC and
SHF_COMPRESSED SHT_RELA section, ie. a compressed dynamic reloc
section. BFD doesn't handle compressed relocation sections, with most
of the code reading relocs using sh_size (often no bfd section is
created) but in the case of SHF_ALLOC dynamic relocs we had some code
using the bfd section size. This led to a mismatch, sh_size is
compressed, size is uncompressed, and from that some uninitialised
memory. Consistently using sh_size is enough to fix this PR, but I've
also added tests to exclude SHF_COMPRESSED reloc sections from
consideration.

bfd_malloc_and_get_section does size sanity checking before allocating
memory and reading contents. These size checks are not done for bss
style sections, because they typically don't occupy file space and
thus can't be compared against file size. However, if you are
expecting to look at something other than a whole lot of zeros, don't
allow fuzzers to avoid the size checking.

Since commit 9833b7757d24, "PR28824, relro security issues",
ELF_MAXPAGESIZE matters much more, with regards to layout of
the linked file. That commit fixed an actual bug, but also
exposes a problem for targets were that value is too high.
For example, for ARM(32, a.k.a. "Aarch32") specifically
bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU)
targets pay an extra amount of up to 60 KiB of bloat in
DSO:s and executables. This matters when there are many
such files, and where storage is expensive.
It's *mostly* bloat when using a Linux kernel, as ARM(32) is
a good example of an target where ELF_MAXPAGESIZE is set to
an extreme value for an obscure corner-case. The ARM
(32-bit) kernel has 4 KiB pages, has had that value forever,
and can't be configured to any other value. The use-case is
IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but
not just that, but a setup where the Linux page-size is
configured to something other than the *default* 4 KiB. Not
sure there actually any such systems in use, again with
both Aarch32 compatibility support and a non-4KiB pagesize,
with all the warnings in the kernel config and requiring the
"EXPERT" level set on.
So, let's do like x86-64 in a2267dbfc9e1 "x86-64: Use only
one default max-page-size" and set ELF_MAXPAGESIZE to 4096.
bfd:
* elf32-arm.c (ELF_MAXPAGESIZE): Always set to 0x1000.

The warning about discarded sections in elf_link_input_bfd doesn't
belong there since the code is dealing with symbols. Multiple symbols
in a discarded section will result in multiple identical warnings
about the section. Move the warning to a new function in ldlang.c.
The patch also tidies the warning quoting of section and file names,
consistently using `%pA' and `%pB'. I'm no stickler for one style of
section and file name quoting, but they ought to be consistent within
a warning, eg. see the first one fixed in ldlang.c, and when a warning
is emitted for multiple targets they all ought to use exactly the same
format string to reduce translation work. elf64-ppc.c loses the
build_one_stub errors since we won't get there before hitting the

So we had a zlib-gabi .debug_info section that increased in size with
zstd, so much so that it was better to leave the section
uncompressed. Things went horribly wrong when the section was read
again later. The section was read again off disk using the
uncompressed size. So you get the zlib section again with some
garbage at the end. Fix that particular problem by setting the
section flag SEC_IN_MEMORY. Any future read will get sec->contents.
Also, if the section is to be left uncompressed, the input
SHF_COMPRESSED flag needs to be reset otherwise objcopy will copy it
to output.

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.

This was detected when a user accidentally tried to build a shared
library using armv8-m.main objects. The resulting error was "warning:
thumb-1 mode PLT generation not currently supported". Something was
clearly wrong because v8-m.main is a thumb-2 variant.
It turns out that the code to detect thumb-2 in object files hadn't
been updated for the extended definition of Tag_THUMB_ISA_use to
support the value 3, meaning 'work it out for yourself from the
architecture tag'; something that is now necessary given that the line
between thumb-1 and thumb-2 has become blurred over time.
Another problem with the function doing this calculation was that the
absence of this tag (implying a default value 0) should mean use of
thumb code was NOT permitted. However, the code went on to look at
the architecture flags and decide that it could ignore this if the
architecture flags said that thumb2 features were available, thus
completely ignoring the intended meaning.

There is really no need to write code like "foo != 0 ? TRUE : FALSE"
unless we had stupidly defined FALSE as something other than 0 or TRUE
as something other than 1. The simpler "foo != 0" does just as well.
Similarly "(condition == TRUE)" or "(condition == FALSE) can be
simplified to "(condition)" and "(!condition)" respectively.
I'll note that there is reason to use "integer_expression != 0" when
assigning a bfd_boolean rather than the simpler "integer_expression",
if you expect the variable to have 0 or 1 value. It's probably even a
good idea to not rely on implicit conversion if bfd_boolean were _Bool.
