* Extended the --out-implib=<file> option, previously restricted to x86 PE
targets, to any ELF based target. This allows the generation of an import
library for an ELF executable, which can then be used by another application
to link against the executable.
Changes in 2.27:
* Add a configure option --enable-relro to decide whether -z relro should
be enabled in ELF linker by default. Default to yes for all Linux
targets except FRV, HPPA, IA64 and MIPS.
* Support for -z noreloc-overflow in the x86-64 ELF linker to disable
relocation overflow check.
Properly implement STT_COMMON The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default. Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF common symbols. bfd/ PR ld/19645 * bfd.c (bfd): Change flags to 20 bits. (BFD_CONVERT_ELF_COMMON): New.

[x86] Resolve non-PIC undefweak symbols in executable For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

ld: Extend options for altering orphan handling behaviour. Replace the options --warn-orphan and --no-warn-orphan with a single option --orphan-handling=MODE, where mode can be place, warn, error, and discard. Mode 'place' is the default, and is the current behaviour, placing the orphan section into a suitable output section. Mode 'warn' is the same as '--warn-orphan'. The orphan is also placed using the same algorithm as for 'place'. Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'. Mode 'discard' assigns all output sections to the /DISCARD/ section. ld/ChangeLog: * ld.h (enum orphan_handling_enum): New. (ld_config_type): Remove warn_orphan, add orphan_handling. * ldemul.c (ldemul_place_orphan): Remove warning about orphan sections. * ldlang.c (ldlang_place_orphan): New function.

2015-07-28 20:20:37 +02:00
* New command line option, --orphan-handling=[place|warn|error|discard], to
adjust how orphan sections are handled. The default is 'place' which gives
the current behaviour, 'warn' and 'error' issue a warning or error
respectively when orphan sections are found, and 'discard' will discard all
orphan sections.
* Add support for LLVM plugin.
* Add --print-memory-usage option to report memory blocks usage.
ld: Add '--require-defined' command line option. Add a new command line option '--require-defined' to the linker. This option operates identically to the '--undefined' option, except that if the symbol is not defined in the final output file then the linker will exit with an error. When making use of --gc-section, or just when trying to pull in parts of a library, it is not uncommon for a user to use the '--undefined' command line option to specify a symbol that the user then expects to be defined by one of the object files supplied to the link. However, if for any reason the symbol is not satisfied by an object provided to the link the user will be left with an undefined symbol in the output file, instead of a defined symbol. In some cases the above behaviour is what the user wants, in other cases though we can do better. The '--require-defined' option tries to fill this gap. The symbol passed to the '--require-defined' option is treated exactly as if the symbol was passed to '--undefined', however, before the linker exits a check is made that all symbols passed to '--require-defined' are actually defined, if any are not then the link will fail with an error. ld/ChangeLog: * ld.texinfo (Options): Document --require-defined option. * ldlang.c (struct require_defined_symbol): New structure. (require_defined_symbol_list): New variable. (ldlang_add_require_defined): New function. (ldlang_check_require_defined_symbols): New function.

* PE targets now support a GNU extension to allow the alignment of common
common symbols to be specified. This support uses custom options in
the .drectve section, which will be disregarded by the native tools.
* PE targets now add primitive support for ELF version scripts; symbols
are not versioned, but the local and global symbol visibility directives
are respected when filtering symbols in auto-export mode.
* New option --no-export-dynamic to undo the effect of the -E and
--export-dynamic options.
* ELF: --warn-alternate-em option to warn if an object has alternate
ELF machine code.
* New script function REGION_ALIAS to add alias names to memory regions.

* PE targets no longer make use of the long section names PE extension to
the COFF format when generating executable images, by default. The old
(slightly non-conformant) behaviour can still be invoked by using the
new '--enable-long-section-names' command-line option. It is also enabled
automatically in the presence of un-stripped debug information, as GDB
needs to be able to find the debug info sections by their full names.

* For GNU/Linux systems the linker will now avoid processing any relocations
made against symbols of the STT_GNU_IFUNC type and instead emit them into
the resulting binary for processing by the loader.

symbols in regular objects, or in other dynamic libraries. In the
latter case the library is not linked if it is found in a DT_NEEDED
entry of one of the libraries already linked.

* Add to the PE/PE+ targets the support of two different kinds of
pseudo-relocations. They can be selected by the switches
--enable-runtime-pseudo-reloc-v1 and --enable-runtime-pseudo-reloc-v2.
For the switch --enable-runtime-pseudo-reloc it uses for 32-bit
runtime pseudo relocation version one, for 64-bit the version two.
Changes in 2.19:
* Linker scripts support a new INSERT command that makes it easier to
augment the default script.
* Linker script input section filespecs may now specify a file within an
archive by writing "archive:file".
* The --sort-common switch now has an optional argument which specifies the
direction of sorting.

the --got=<type> command line option.
* The ARM EABI linker will now generate stubs for function calls to symbols
that are too far away. The placement of the stubs is controlled by a new
linker command line option: --stub-group-size=N.
2007-08-10 15:21:40 +02:00
Changes in 2.18:
2007-07-06 16:09:45 +02:00

symbol table in the executable.
* The default output section LMA has changed for allocatable sections from
being equal to VMA, to keeping the difference between LMA and VMA the same as
the previous output section in the same region. This is a more useful
default when using overlays and other cases where you specify an LMA

* Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
* Modify the Linux linker search order to better match ld.so search order.
Look for DT_NEEDED libraries in paths specified by ld.so.conf before
searching the default directories, rather than vice versa.
Use $prefix/etc/ld.so.conf if it exists, otherwise /etc/ld.so.conf.
* PE-COFF: Forward exports from DLL's can now be specified in .def files
passed directly to ld.
* Support for the Z80 processor family has been added.
* Add support for the "@<file>" syntax to the command line, so that extra
switches can be read from <file>.
2005-03-15 18:49:15 +01:00
Changes in 2.16:
* Support for the R_ARM_V4BX relocation as defined in the ARM AAELF

* New linker script construct AS_NEEDED(), which sets the --as-needed flag
for input files listed inside of it.
* A new command-line option, --sysroot, can be used to override the
default sysroot location. It only applies to toolchains that were
configured using --with-sysroot.
* New linker script functions: ORIGIN() and LENGTH() which return information
about a specified memory region.
2004-11-08 14:17:43 +01:00

2004-05-21 17:38:04 +02:00
* A new linker command line switch has been added which allows the hash table
size to be set to a suitable prime value near to its argument. This switch
is --hash-size=<NUMBER>. Also if the switch --reduce-memory-overheads is
used, and --hash-size has not been used, then the default value will be set
to 1021.
* Linker map files are now generated with an O(N) algorithm for finding symbols
that are defined in each section. This uses about 40% more memory for
symbols than the old O(N^2) algorithm. You can use the new
--reduce-memory-overheads option to select the old algorithm; this option
might also be used in the future to select similar tradeoffs.
2004-05-21 17:38:04 +02:00
Changes in 2.15:
* ELF: --as-needed/--no-as-needed options to control if a DT_NEEDED tag should

is defined before the statement where DEFINED is used.
* The MIPS --embedded-relocs (used to embed relocations into binaries for
Embedded-PIC code) is deprecated and will be removed in a future release.
* cr16c support added by NSC.
* m32r Linux (ELF) support added by Renesas.
2003-08-20 10:37:19 +02:00
* Improved linker's handling of unresolved symbols. The switch
--unresolved-symbols=<method> has been added to tell the linker when it
should report them and the switch --warn-unresolved-symbols has been added to
make reports be issued as warning messages rather than errors.

2001-08-23 17:14:18 +02:00
* Support for -z combreloc in the ELF linker, which puts dynamic
relocations against the same symbol together, so that dynamic linker
can use an one-entry symbol lookup cache.
* Support for ELF SHF_MERGE section merging, by Jakub Jelinek.
2002-02-20 11:46:54 +01:00
Changes in version 2.11:
* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
* Support added for eliminating duplicate DWARF2 debug information by
having the compiler generate the information in sections called
.gnu.linkonce.wi.XXXX where XXXX is a checksum for the contents. The
linker then merges these sections together into the normal .debug_info
section.
1999-05-03 09:29:11 +02:00
* The native ELF linker now searches the directories in DT_RUNPATH or
DT_RPATH of a shared library for shared libraries needed by it.
2000-06-20 15:31:59 +02:00
* TI C54x support, by Timothy Wall.
* Added command line switch --section-start to set the start address of any
specified section.
* Added ability to emit full relocation information in linked executables,
enabled by --emit-relocs. Some post-linkage optimization tools need
this information in order to be able to correctly identify and perform
symbol relative addressing in the event of changes in section contents
(instructions being added or deleted, extending data sections, etc.)
* Support for i860, by Jason Eckhardt (preliminary, alpha quality).
2000-08-24 19:42:52 +02:00
* Support for CRIS (Axis Communications ETRAX series).
* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
Changes in version 2.10:
* Added AT> to the linker script language to allow load-time allocation of
2000-04-07 19:04:19 +02:00
sections into regions.
* Added garbage collection of unused sections, enabled by --gc-sections.
1999-05-03 09:29:11 +02:00
It does require a bit of backend support; currently implemented are
2000-06-24 06:48:41 +02:00
arm-elf, avr-elf, d10v-elf, fr30-elf, i386-elf, m32r-elf, m68k-elf,
mcore-elf, mips-elf, mn10300-elf, ppc-elf, sh-elf, sparc-elf, and v850-elf.
Others will ignore the option.
1999-05-03 09:29:11 +02:00
* Added SORT to the linker script language to permit sorting sections by file
name or section name.
* Added EXTERN to the linker script language as an equivalent to the -u
command-line option.
* Added ASSERT to the linker script language.
1999-06-13 12:20:50 +02:00
* Added EXCLUDE_FILE to the linker script language for further control over
wildcard file names.
1999-05-03 09:29:11 +02:00
* Added -O option to optimize linker output (as of this writing, this only
affects ELF shared library generation).
1999-05-03 09:29:11 +02:00
* The -e option now accepts a number as well as a symbol name.
1999-06-13 21:25:57 +02:00
* Added --no-undefined option to disallow undefined symbols when creating a
shared library.
2000-03-02 02:26:27 +01:00
* The linker now issues a warning, not an error, for an undefined symbol when
using -Bsymbolic; use the new --no-undefined option to get the old
behaviour.
1999-05-03 09:29:11 +02:00
* Added --demangle and --no-demangle options.
Changes in version 2.9:
* Added SQUAD to the linker script language.
* New option --no-warn-mismatch.
* The MEMORY command now parses the attributes to determine where sections that
are not placed in a specific memory region are placed.
Changes in version 2.8:
* Linker scripts may now contain shell wildcard characters for file and section
names.
* The linker now supports symbol versions in ELF.
* The NOCROSSREFS command was added to the linker script language.
* The LOADADDR expression was added to the linker script language.
* MAX and MIN functions were added to the linker script language.
* The OVERLAY construct was added to the linker script language.
* New option --warn-section-align to warn when the address of an output section
changes due to alignment of an input section.
* New options --filter/-F and --auxiliary/-f.
Changes in version 2.7:
* New option --cref to print out a cross reference table.
* New option --wrap SYMBOL.
* New option --no-whole-archive, to turn off the effect of --whole-archive.
* Input sections assigned to the output section /DISCARD/ in the linker script
are not included in the output file.
* The SunOS and ELF linkers now merge stabs debugging information which uses
the N_BINCL and N_EINCL stab types. This reduces the amount of debugging
information generated.
Changes in version 2.6:
* When an ELF section name is representable as a C identifier (this is not true
of most ELF section names), the linker will automatically define symbols
__start_SECNAME and __stop_SECNAME, where SECNAME is the section name, at the
beginning and the end of the section. This is used by glibc.
Addendum: Current versions of the linker (at least for version 2.18 onwards
and possibly much earlier as well) place two restrictions on this feature: The
symbols are only implemented for orphaned sections, not for explicitly placed
sections and they are PROVIDEd rather than being defined.
1999-05-03 09:29:11 +02:00
* When an ELF section named .gnu.warning is encountered in an input file, the
contents of the section are displayed as an error message, and the section is
not copied into the output file. This is used by glibc.
* When an ELF section named .gnu.warning.SYMBOL is encountered in an input
file, and the symbol SYMBOL is referenced by some object file, the contents of
the section are displayed as an error message. The section is not copied into
2003-06-25 08:40:27 +02:00
the output file, unless doing a relocatable or shared link. This is used by
1999-05-03 09:29:11 +02:00
glibc.
* New options -split-by-reloc and -split-by-file.
* The linker now supports linking PIC compiled code on SPARC SunOS. It can
also create SPARC SunOS shared libraries, and, like the native SunOS linker,
will do so whenever there is an undefined symbol in the link and neither the -e
nor the -r option was used.
* The -rpath option may be used on SunOS to set the list of directories to be
searched at run time. This overrides the default of building the list from the
-L options.
* The COFF linker now combines debugging information for structs, unions, and
enums, so that even if the same type is defined in multiple input files it will
only be defined once in the output file. The --traditional-format switch will
prevent this optimization.
Changes in version 2.5:
* The linker now supports linking against SunOS shared libraries. It still can
not link SunOS PIC (Position Independent Code) files, so it can not be used to
generate shared libraries.
1999-05-03 09:29:11 +02:00
* The linker now supports linking against ELF shared libraries for the i386
(UnixWare) and SPARC (Solaris). It can also link ELF PIC files, and can be
used to generate shared libraries. Shared library generation is not well
tested; please report any problems encountered. The linker is now enabled for
Solaris again.
* Eric Youngdale has contributed Linux support code, including linking against
Linux a.out shared libraries. The linker produces Linux QMAGIC binaries.
* The ELF backend has been converted to the new linker code. To use the new
ELF linker, each particular target requires a relocation function. So far,
this function has been written for i386 (UnixWare), SPARC (Solaris) MIPS (Irix
5), and HPPA ELF targets.
* The -( (--start-group) and -) (--end-group) options have been added to
support searching a group of archives as though they were a single archive.
This can also be used in a linker script, as GROUP ( files ).
* When a file is named on the command line, and the linker does not recognize
it as an object file, the linker will now treat the file as a linker script
file. A linker script named in this way augments, but does not replace, the
default linker script.
* The -warn-once option was added. It causes the linker to only warn once per
undefined symbol, rather than once per reference.
* The COFF backend has been converted to the new linker code. As with ELF, to
use the new linker, each particular target requires a relocation function. So
far, this function has been written for the i386, m68k, a29k and SH targets.
* The -V flag was made a synonym for -v, for SVR4 compatibility. The old -V
behaviour is available via --verbose.
Changes in version 2.4:
* New linker code, by Steve Chamberlain and Ian Taylor. For a.out and ecoff
formats (so far), this should result in considerable savings in time
and memory used while linking; slightly poorer performance than
before for formats not converted yet.
* Command-line parsing is no longer done with flex. This means
oddball characters in filenames won't get treated as argument
separators.
* HP-PA ELF support, by Jeff Law. (No SOM support yet.)
* Mach i386 support, by David Mackenzie.
* Irix 4 shared libraries are now supported (Irix 5 uses ELF, and ELF shared
libraries are not yet supported).
* COFF shared libraries (as on SCO) should work as well.
* The linker is disabled for Solaris. (Actually, it was in 2.3 also, I just
forgot to note it.) Some of their C library routines don't work when
statically linked, and the GNU linker doesn't support dynamic linking yet.
Changes in version 2.3:
* Weak symbols are now supported.
* ELF support has been added. The linker has been bootstrapped on
UnixWare and Solaris.
* Alpha OSF/1 support has been added (non dynamic linking only).
Changes in version 2.2:
* The `bfd' library has been updated to reduce a.out-format string
table size. The effect of this is that files linked from many input
files with duplicate symbols (`-g' debugging records, or identical
static symbols) should be much smaller.
Changes in version 2.1:
* The ld -ySYMBOL flag (to trace references to SYMBOL) is now implemented.
* There is now support for writing ECOFF files, so ld and the
other utilities should work on Risc/Ultrix and Irix.
