PR29397 PR29563: Add new configure option --with-zstd which defaults to
auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support
zstd compressed debug sections for most tools.
* bfd: for addr2line, objdump --dwarf, gdb, etc
* gas: support --compress-debug-sections=zstd
* ld: support ELFCOMPRESS_ZSTD input and --compress-debug-sections=zstd
* objcopy: support ELFCOMPRESS_ZSTD input for
--decompress-debug-sections and --compress-debug-sections=zstd
* gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd
symbols, so gdb has to link against -lzstd in this patch.
If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We
can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this
is too heavyweight, so don't do it for now.

* ldmain.c (main): Don't access output_bfd after bfd_close.

Commit f493c2174e messed the formatting in linker map files,
particularly for 32-bit builds where a number of tests using map files
regressed. I should have noticed the BFD64 conditional printing of
spaces to line up output due to the original %V printing hex vmas with
16 digits when BFD64 and 8 digits when not. Besides that, it is nicer
to print 32-bit vmas for 32-bit targets. So change %V back to be
target dependent, now using bfd_sprintf_vma. Since minfo doesn't
return the number of chars printed, that means some places that
currently use %V must instead sprintf to a buffer in order to find the
length printed.
* ldmisc.h (print_spaces): Declare.

The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

If GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS is set on any input
relocatable files:
1. Don't generate copy relocations.
2. Turn off extern_protected_data since it implies
GNU_PROPERTY_NO_COPY_ON_PROTECTED.
3. Treate reference to protected symbols with indirect external access
as local.
4. Set GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS on output.
5. When generating executable, clear this bit when there are non-GOT or
non-PLT relocations in input relocatable files without the bit set.
6. Add -z [no]indirect-extern-access to control indirect external access.

When link_info.keep_memory is true, linker caches the relocation
information and symbol tables of input files in memory. When there
are many input files with many relocations, we may run out of memory.

In commit 89753bbf81 I enabled a warning for scripts redefining
symbols. The idea was to not warn for symbols defined by shared
libraries (the h->u.def.section->output_section != NULL test), but the
test failed to take into account absolute symbols. Absolute symbols
defined in shared libraries are currently indistinguishable from
absolute symbols defined in relocatable objects, at least when only
looking at struct bfd_link_hash_entry. So, don't warn for any
absolute symbols.

When --gc-sections is in effect, a reference from a retained section
to __start_SECNAME or __stop_SECNAME causes all input sections named
SECNAME to also be retained, if SECNAME is representable as a C
identifier and either __start_SECNAME or __stop_SECNAME is synthesized
by the linker. Add an option to disable that feature, effectively
ignoring any relocation that references a synthesized linker defined
__start_ or __stop_ symbol.

This is embarrassing.
The whole point of CTF is that it remains intact even after a binary is
stripped, providing a compact mapping from symbols to types for
everything in the externally-visible interface of an ELF object: it has
connections to the symbol table for that purpose, and to the string
table to avoid duplicating symbol names. So it's a shame that the hooks
I implemented last year served to hook it up to the .symtab and .strtab,
which obviously disappear on strip, leaving any accompanying the CTF
dict containing references to strings (and, soon, symbols) which don't
exist any more because their containing strtab has been vaporized. The
original Solaris design used .dynsym and .dynstr (well, actually,
.ldynsym, which has more symbols) which do not disappear. So should we.
Thankfully the work we did before serves as guide rails, and adjusting
things to use the .dynstr and .dynsym was fast and easy. The only
annoyance is that the dynsym is assembled inside elflink.c in a fairly
piecemeal fashion, so that the easiest way to get the symbols out was to
hook in before every call to swap_symbol_out (we also leave in a hook in
front of symbol additions to the .symtab because it seems plausible that
we might want to hook them in future too: for now that hook is unused).
We adjust things so that rather than being offered a whole hash table of
symbols at once, libctf is now given symbols one at a time, with st_name
indexes already resolved and pointing at their final .dynstr offsets:
it's now up to libctf to resolve these to names as needed using the
strtab info we pass it separately.
Some bits might be contentious. The ctf_new_dynstr callback takes an
elf_internal_sym, and this remains an elf_internal_sym right down
through the generic emulation layers into ldelfgen. This is no worse
than the elf_sym_strtab we used to pass down, but in the future when we
gain non-ELF CTF symtab support we might want to lower the
elf_internal_sym to some other representation (perhaps a
ctf_link_symbol) in bfd or in ldlang_ctf_new_dynsym. We rename the
'apply_strsym' hooks to 'acquire_strings' instead, becuse they no longer
have anything to do with symbols.
There are some API changes to pieces of API which are technically public
but actually totally unused by anything and/or unused by anything but ld
so they can change freely: the ctf_link_symbol gains new fields to allow
symbol names to be given as strtab offsets as well as strings, and a
symidx so that the symbol index can be passed in. ctf_link_shuffle_syms
loses its callback parameter: the idea now is that linkers call the new
ctf_link_add_linker_symbol for every symbol in .dynsym, feed in all the
strtab entries with ctf_link_add_strtab, and then a call to
ctf_link_shuffle_syms will apply both and arrange to use them to reorder
the CTF symtab at CTF serialization time (which is coming in the next
commit).
Inside libctf we have a new preamble flag CTF_F_DYNSTR which is always
set in v3-format CTF dicts from this commit forwards: CTF dicts without
this flag are associated with .strtab like they used to be, so that old
dicts' external strings don't turn to garbage when loaded by new libctf.
Dicts with this flag are associated with .dynstr and .dynsym instead.
(The flag is not the next in sequence because this commit was written
quite late: the missing flags will be filled in by the next commit.)
Tests forthcoming in a later commit in this series.

If an archive map contains symbols that aren't actually defined by the
indexed element for any reason, then loading that element will leave
the symbol undefined (or common). This leads to the possibility of
the element being loaded again should the archive be searched again

triggering this problem was an archive containing fat lto objects,
with the archive map incorrectly created by ar rather than gcc-ar.

This is quite complicated because the CTF section's contents depend on
the final contents of the symtab and strtab, because it has two sections
whose contents are shuffled to be in 1:1 correspondence with the symtab,
and an internal strtab that gets deduplicated against the ELF strtab
(with offsets adjusted to point into the ELF strtab instead). It is
also compressed if large enough, so its size depends on its contents!
So we cannot construct it as early as most sections: we cannot even
*begin* construction until after the symtab and strtab are finalized.
Thankfully there is already one section treated similarly: compressed
debugging sections: the only differences are that compressed debugging
sections have extra handling to deal with their changing name if
compressed (CTF sections are always called ".ctf" for now, though we
have reserved ".ctf.*" against future use), and that compressed
debugging sections have previously-uncompressed content which has to be
stashed away for later compression, while CTF sections have no content
at all until we generate it (very late).
BFD also cannot do the link itself: libctf knows how to do it, and BFD
cannot call libctf directly because libctf already depends on bfd for
file I/O. So we have to use a pair of callbacks, one, examine_strtab,
which allows a caller to examine the symtab and strtab after
finalization (called from elf_link_swap_symbols_out(), right before the
symtabs are written, and after the strtab has been finalized), and one
which actually does the emission (called emit_ctf simply because it is
grouped with a bunch of section-specific late-emission function calls at
the bottom of bfd_elf_final_link, and a section-specific name seems best
for that). emit_ctf is actually called *twice*: once from lang_process
if the emulation suggests that this bfd target does not examine the
symtab or strtab, and once via a bfd callback if it does. (This means
that non-ELF targets still get CTF emitted, even though the late CTF
emission stage is never called for them).
v2: merged with non-ELF support patch: slight commit message
adjustments.
v3: do not spend time merging CTF, or crash, if the CTF section is
explicitly discarded. Do not try to merge or compress CTF unless
linking.
v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's
after writeout: set SEC_IN_MEMORY on the output contents so a future
bfd enhancement knows it could free it. Add SEC_LINKER_CREATED |
SEC_KEEP to avoid having to add .ctf to the linker script. Drop
now-unnecessary ldlang.h-level elf-bfd.h include and hackery around
it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c
changes.
v5: fix tabdamage. Drop #inclusions in .h files: include in .c files,
.em files, and use struct forwards instead. Use bfd_section_is_ctf

"next" and "next_real_file" in lang_input_statement_type always point
to another lang_input_statement_type, so it makes sense for these to

Add a new option to disable the listing of discarded sections
in map file output. The use case stems from a large application

allows us to disable it.

Similarly to commit 174d0a74a2e6 ("PowerPC/BFD: Convert `%P: %H:' to
`%H:' in error messages") convert linker relocation error messages to
use `%H:' rather `%P: %H:', removing inconsistent message composition
like:
$ cat reloc-j.s
.text
.globl foo
.ent foo
foo:
j bar
j bar
.end foo
$ cat reloc-j.ld
SECTIONS
{
bar = 0x12345678;
.text : { *(.text) }
/DISCARD/ : { *(*) }
}
$ as -o reloc-j.o reloc-j.s
$ ld -T reloc-j.ld -o reloc-j reloc-j.o
ld: tmpdir/reloc-j.o: in function `foo':
(.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar'
ld: (.text+0x8): relocation truncated to fit: R_MIPS_26 against `bar'
$
where subsequent lines referring to issues within a single function have
the name of the linker executable prepended, but the first one does not.
As noted with the commit referred this breaks a GNU Coding Standard's
requirement that error messages from compilers should look like this:
source-file-name:lineno: message
also quoted in `vfinfo' code handling these specifiers.
Remove the linker name prefix then, making the messages now look like:
$ ld -T reloc-j.ld -o reloc-j reloc-j.o
tmpdir/reloc-j.o: in function `foo':
(.text+0x0): relocation truncated to fit: R_MIPS_26 against `bar'
(.text+0x8): relocation truncated to fit: R_MIPS_26 against `bar'
$
instead.

The idea of this change is to make -t output useful for users wanting
to package all the object files involved in linking for a bug report.
Something like the following should do the trick.
gcc hello.c -save-temps -Wl,-t | xargs realpath | sort | uniq > files
tar cJf test.tar.xz `cat files`
* ldlang.c (load_symbols): When -t, print file names for script
files and archives.
* ldmain.c (trace_files): Make an int.
(add_archive_element): Print archive elements only with multiple
-t options, or when archive is thin.
* ldmain.h (trace_files): Update.
* ldmisc.c (vfinfo): Don't print both original path and path in
sysroot.
* lexsup.c (parse_args <t>): Increment trace_files.
|
|
This output really belongs in ld --verbose.
* ldmain.c (main): Print emulation mode and "deleting executable"
for --verbose, not --trace.
(add_archive_element): Only print "no new IR symbols" for --verbose.
|
|
Prepending '/' to absolute paths doesn't gain us much, and results in
the current implementation of --trace emitting silly path-in-sysroot
output, eg.
/lib/ld-linux-x86-64.so.2 (//lib/ld-linux-x86-64.so.2)
* ldmain.c (get_sysroot): Return "" for "--sysroot=/".

This patch performs a run-time test that a shared libbfd.so has been
compiled with the same size bfd_vma as that of apps using the library.
On a 32-bit host it is easily possible to have one libbfd.so compiled
to support 64-bit targets (or configured with --enable-64-bit-bfd)
while another only supports 32-bit targets. The two libraries will
have differently sized bfd_vma types, and if the wrong one is loaded
all sorts of weird behaviour might be seen.

max-page-size only matters for demand paged executables or shared
libraries, and the ideal size is the largest value used by your
operating system. Values larger than necessary just waste file space
and memory. common-page-size also affects file and memory size,
trading a possible small increase in file size for a decrease in
memory size when the operating system is using a common-page-size
page. With a powerpc max-page-size of 64k and common-page-size of 4k
many executables will use no more memory pages when the system page
size is 4k than an executable linked with -z max-page-size=0x1000,
yet will still run on a system using 64k pages. However, when running
on a system using 64k pages relro protection will not be completely
effective.
Due to the relro problem, powerpc binutils has been using a default
common-page-size of 64k since 2014-12-18 (git commit 04c6a44c7),
leading to complaints about increased file and memory sizes. People
not using relro do have a valid reason to complain..
So this patch introduces an extra back-end value to use as the default
for common-page-size when generating relro executables, and enables
the support for powerpc. Non relro executables will now be generated
with a default common-page-size of 4k.

This patch standardizes messages in ld, to better conform to the GNU
coding standard. Besides issues of capitalization and full-stops,
I've
- Split up help messages for target options, so that adding a new
option does not mean loss of translation for all the others.
- Embedded tabs have been removed, since a user might have tab stops
set at other than 8 char intervals.
- Added missing program name (%P). ld isn't the compiler.
- Put %F and %X first (and removed %X if %F was present). These can
go anywhere, but look silly in the m%Fiddle of a message, and
choosing "%P%F:" in some messages but "%F%P:" in others leads to the
likelihood of duplication in ld.pot. Besides, the colon belongs
with %P.

ld ought to be more clever about where it puts LTO recompiled objects.
Ideally the recompiled objects ought to be ordered to the same place
their IR objects were, and files extracted from archives on the second
pass ought to go in the same place as they would if extracted on the
first pass. This patch addresses the archive problem. Without this
fix, objects extracted from archives might be placed after the crt
files intended to go at the end of an executable or shared library,
possibly causing exception handling failures.
