@chapter General
@section Introduction
@command{vlink} is a portable linker which can be configured to support multiple
input and output file formats at once. It even allows to link input files
with a different format in a single run and generate the output file format
of your choice from it.
The linker supports linking with objects, object archives (static libraries)
and shared objects or libraries. It can generate an executable file with or
without additional information for dynamic linking, a shared object, or
a new object suitable for another linker pass.
Empty sections and other unused data are deleted to achieve a size-optimized
output.
@section Legal
@command{vlink} is freeware and part of the portable and retargetable ANSI C
compiler vbcc, copyright (c) 1995-2010 by Volker Barthelmann.
@command{vlink} may be freely redistributed as long as no modifications are
made and nothing is charged for it. Non-commercial usage is allowed
without any restrictions.
Every product or program derived directly from my source may not be
sold commercially without permission from the author.
@section Installation
@command{vlink} comes as a stand-alone program, so no further
installation is necessary.
To use @command{vlink} with @command{vbcc}, copy the binary to
@file{vbcc/bin}, following the installation instructions for
@command{vbcc}.
@chapter The Linker
@section Usage
@command{vlink} links the object and archive files given on the command line
into a new object file. The output object file is either an executable
program, a shared object suitable for loading at run-time, or an
object file that can once again be processed by @command{vlink}.
Object files and archives are processed in the order given on the command
line. Unlike other linkers you usually have to specify each library to link
against only once, as @command{vlink} is smart enough to figure out all dependencies.
The file format of an input object file is determined automatically
by the linker. The default output file format is compiled in
(see @option{-v}) and may be changed by @option{-b}. Optionally, the default
library search path can also be compiled in and is visible with
@option{-v} as well.
The number of output file formats included is configurable at compile time.
@section Supported file formats
The following file formats are supported:
@table @code
@item amigahunk
The AmigaDos hunk format for M68k. Requires AmigaOS 2.04.
No shared objects. Small data offset @code{0x7ffe}. Linker symbols:
@itemize @minus
@item _DATA_BAS_ (PhxAss)
@item _DATA_LEN_ (PhxAss)
@item _BSS_LEN_ (PhxAss)
@item _LinkerDB
@item __BSSBAS (SASC/StormC)
@item __BSSLEN (SASC/StormC)
@item __ctors (SASC/StormC)
@item __dtors (SASC/StormC)
@item __DATA_BAS (DICE-C)
@item __DATA_LEN (DICE-C)
@item __BSS_LEN (DICE-C)
@item __RESIDENT (DICE-C)
@item ___machtype (GNU-gcc)
@item ___text_size (GNU-gcc)
@item ___data_size (GNU-gcc)
@item ___bss_size (GNU-gcc)
@end itemize
Automatic constructor/destructor function tables:
@code{__ctors} and @code{__dtors} (will be mapped automatically to
@code{__CTOR_LIST__} and @code{__DTOR_LIST__}).
Supports @option{-Rstd} and @option{-Rshort}.
This format was called "amigaos" in former @command{vlink} versions.
@item amigaehf
An extension of the AmigaDOS hunk format for the PowerPC,
32-bit, big endian, as introduced by Haage&Partner GmbH. No
executables (they are in @code{amigahunk} format) or shared objects.
The same linker symbols, constructors/destructors as under
amigaos are supported. Additionally, @code{@@_name} symbols will
be created on demand (when referenced).
Supports @option{-Rstd} and @option{-Rshort}.
@item ataritos
Atari-ST TOS file format. Executables only at the moment.
The internal linker script defines _LinkerDB for small
data and supports @command{vbcc}-style
constructor/destructor tables
in the data section (@code{__CTOR_LIST__} and @code{__DTOR_LIST__}).
@item elf32m68k
ELF (executable linkable format) for Motorola M68k, 32-bit,
big endian. Small data offset: @code{0x8000}. Linker symbols:
@code{_SDA_BASE_}. Automatic constructor/destructor function
tables will be placed into the sections @code{.ctors} and @code{.dtors}.
Supports @option{-Rstd} and @option{-Radd}.
@item elf32i386
ELF (executable linkable format) for Intel 386 and better,
32-bit, little endian. No small data. Automatic constructor/destructor
function tables will be placed into the sections
@code{.ctors} and @code{.dtors}.
Supports @option{-Rstd} and @option{-Radd}.
@item elf32aros
ELF i386 32-bit little endian like elf32i386, but generates
relocatable object files as executables. This format is
used for the AROS (Amiga Research OS) operating system.
Supports @option{-Rstd} and @option{-Radd}.
@item elf32arm
ELF (executable linkable format) for the ARM architecture.
32-bit, little endian. Small data offset: @code{0x1000}. Linker
Symbols: @code{_SDA_BASE_}. Automatic constructor/destructor
function tables will be placed into the sections @code{.ctors}
and @code{.dtors}. Supports @option{-Rstd} and @option{-Radd}.
@item elf32ppcbe
ELF (executable linkable format) for PowerPC, 32-bit,
big endian. Small data offset: @code{0x8000}. Linker symbols:
@code{_SDA_BASE_} and @code{_SDA2_BASE} (EABI only). Automatic
constructor/destructor function tables will be placed into the
sections @code{.ctors} and @code{.dtors}.
@item elf32powerup
ELF PowerPC 32-bit big endian like elf32ppcbe, but generates
relocatable object files as executables. This format is
used for the PowerUp kernel. The linker symbol @code{_LinkerDB} is
defined for @command{vbccppc}-compatibility.
Small data offset: @code{0x8000}.
This format was also called @code{elf32amiga} in former @command{vlink}
versions.
@item elf32morphos
Nearly identical to elf32powerup. Only difference is that
@code{.sdata} and @code{.sbss} sections will not be merged as the MorphOS
loader will take care of it. This format is used for MorphOS.
@item elf32amigaos
Identical to elf32ppcbe, but when doing dynamic linking it requires that
also all references from shared objects are resolved at link time. This
is due to a limitation of the AmigaOS4 dynamic link editor (elf.library).
@item a.out
Currently supported:
@itemize @minus
@item aoutnull (Default with standard relocs and undefined endianess)
@item aoutbsd68k (NetBSD/68k)
@item aoutbsd68k4k (NetBSD/68k 4K page size)
@item aoutsun010 (SunOS 68010 and AmigaOS/Atari 68000/010)
@item aoutsun020 (SunOS 68020 and AmigaOS/Atari 68020-68060)
@item aoutbsdi386 (NetBSD/i386)
@item aoutpc386
@item aoutmint (Embeds a.out in TOS format for Atari MiNT executables)
@item aoutjaguar (M68k with special, word-swapped RISC relocations)
@end itemize
Small data offset: @code{0x8000} (unused).
Linker symbols:
@code{__GLOBAL_OFFSET_TABLE_}, @code{__PROCEDURE_LINKAGE_TABLE_},
@code{__DYNAMIC}.
@item vobj-le
@itemx vobj-be
VOBJ file format, generated by the @command{vasm} assembler. VOBJ is
a read-only object file format and is designed to support
any little- or big-endian architecture with all their
specific relocations.
@item rawbin1
Absolute raw binary file. The sections and base addresses
have to be specified by a linker script (option @option{-T}). Gaps
between sections are filled with 0-bytes. Without a linker
script, the raw binary will be relocated to base address 0.
@item rawbin2
Similar to rawbin1. The only difference is, that a separate file
will be created for every section. The file name will get
the section's base address appended.
@item srec19
@itemx srec28
@itemx srec37
Motorola S-Record format. No symbols. Output format only.
Without a linker script, the raw binary will be relocated to base address 0.
@item ihex
Intel Hex format. No symbols. Output format only.
Without a linker script, the raw binary will be relocated to base address 0.
@end table
@section Linker Options
@command{vlink} command template:
@example
@command{vlink [-dhnqrstvwxMRSX] [-B linkmode] [-b targetname]
[-baseoff offset] [-C constructor-type] [-EB] [-EL]
[-e entrypoint] [-export-dynamic] [-f flavour] [-fixunnamed]
[-F filename] [-interp path] [-L library-search-path]
[-l library-specifier] [-minalign val] [-multibase] [-nostdlib]
[-o filename] [-rpath path] [-sc] [-sd] [-shared] [-soname name]
[-static] [-T filename] [-Ttext addr] [-textbaserel]
[-tos-flags/fastload/fastram/private/global/super/readable]
[-u symbol] [-V version] [-y symbol] [-P symbol] input-files...}
@end example
Usually options and input file names can be mixed. Order of options may be
important (e.g. when specifying a library with @option{-l} or a search path
with @option{-L}).
The following options are supported:
@table @option
@item -Bdynamic
Specifies that linking against dynamic libraries can take
place. If a library specifier of the form @option{-lx} appears on
the command line, ld searches for a library of the from
@file{libx.so.n.m} (see the @option{-l} option) according to the search
rules in effect. If such a file can not be found a traditional archive
is looked for. This options can appear anywhere on the command line and is
complementary to @option{-Bstatic}.
@item -Bstatic
The counterpart of @option{-Bdynamic}. This option turns off dynamic
linking for all library specifiers until a @option{-Bdynamic} is once
again given. Any explicitly mentioned shared object encountered on the
command line while this option is in effect is flagged as an error.
@item -Bshareable
Instructs the linker to build a shared object from the object
files rather than a normal executable image.
@item -Bsymbolic
This option causes all symbolic references in the output to be
resolved in this link-edit session. The only remaining run-
time relocation requirements are base-relative relocations,
ie. translation with respect to the load address. Failure to
resolve any symbolic reference causes an error to be reported.
@item -Bforcearchive
Force all members of archives to be loaded, whether or not such
members contribute a definition to any plain object files.
Useful for making a shared library from an archive of PIC
objects without having to unpack the archive.
@item -b targetname
Specifies target file format for the output file. See
also "Supported file formats".
@item -baseoff offset
Defines section offset for base-relative relocations. The
default offset is target-dependant (e.g. @code{0x7ffe} for amigaos
and @code{0x8000} for elf32m68k).
@item -C constructor-type
Defines the type of constructor/destructor function names
to scan for. Valid types are:
@table @code
@item gnu
GNU style constructors
@item vbcc
vbcc style constructors: @code{__INIT[_<pri>]_<name> / __EXIT..}
@item vbccelf
vbcc style constructors: @code{_INIT[_<pri>]_<name> / _EXIT..}
@end table
@item -clr-adduscore
No longer add a preceding underscore for the symbols of the
following objects in the command line.
@item -clr-deluscore
No longer delete a preceding underscore for the symbols of the
following objects in the command line.
@item -d
Force allocation of commons even when producing relocatable
output (@option{-r} option).
@item -e entrypoint
Defines the entry point of an executable and may be either
a symbol or an absolute address. The linker will set the
entry point by trying each of the following methods in order,
stopping when the first succeeds:
@enumerate
@item -e option
@item @code{ENTRY()} command in a linker script
@item value of the symbol @code{_start}, if defined
@item start of the first executable code section
@item address 0
@end enumerate
@item -EB
Presets big-endian mode for reading input and writing output.
@item -EL
Presets little-endian mode for reading input and writing output.
@item -export-dynamic
Put all global symbols of the output file into the dynamic symbol table,
making them visible for shared objects loaded on demand (e.g. by
@code{dlopen()}).
@item -f flavour
Adds a library-flavour. All flavours are cumulatively
appended to each library search-path, whenever a library
was specified with @option{-l}.
Example: One search path and two flavours will search in:
@enumerate
@item @file{<lib-path>},
@item @file{<lib-path>/<flavour1>} and
@item @file{<lib-path>/<flavour1>/<flavour2>}
@end enumerate
@item -F filename
A list of object file names is read from the specified file.
Useful, if the number of objects exceeds the length of the command line.
@item -fixunnamed
All unnamed sections will get a default name according to
their section type (@code{.text}, @code{.data} and @code{.bss}).
@item -h
Prints a short help text.
@item -interp interpreter-path
Defines the name of the interpreter, which is usually the
dynamic linker for dynamically linked ELF executables.
Defaults to @file{/usr/lib/ld.so.1}.
@item -L library-search-path
Add path to the list of directories to search for libraries
specified with the @option{-l} option. When a default search path
was compiled in (see @option{-v}), then it is searched last.
@item -l library-specifier
This option specifies a library to be considered for inclusion
in the output. If the @option{-Bdynamic} option is in effect, a shared
library of the form @file{lib<spec>.so.m.n} (where @code{m} is the
major, and @code{n} is the minor version number, respectively) is searched
for first. The library with the highest version found in the
search path is selected. If no shared library is found or
the @option{-Bstatic} option is in effect, an archive of the form
@file{lib<spec>.a} is looked for in the library search path.
For @code{amigaos}/@code{amigaehf} file formats, the libraries are
called @file{<spec>.lib}.
@item -M
Produce output about the mapping of sections of the input
files and the values assigned to symbols in the output file.
@item -minalign alignment
Set a minimum alignment (number of bits which have to be zero) for all
imported sections. The specified @code{alignment} value will only take
effect when higher than the section's current alignment. It defaults to 0.
@item -multibase
The default behaviour of @command{vlink} is to merge all sections
which are accessed base-relative. This guarantees a single
small data section, which can be accessed through a base
register.
If this is not desired - maybe you have several base registers and
small data sections - you can disable this behaviour by specifying
@option{-multibase}.
@item -n
No page alignment of sections or segments in the final
executable (@code{NMAGIC}).
@item -nostdlib
Ignore default library search path, if one was compiled in.
@item -o filename
Specifies the name of the output file. Defaults to @file{a.out}.
@item -P symbol
Protect a symbol from stripping. This doesn't work for all targets!
@item -q
Emit relocations, even for absolute executables.
@item -R format
Sets the relocation table format. Usually there is no need
to change the default format defined by the target (@option{-b} option).
Valid format strings are:
@table @code
@item std
standard format with addends in the code
@item add
addends are stored in the relocation table
@item short
relocation table with short offsets (e.g. 16 bit)
@end table
Note that most targets only support one or two of those formats.
@item -r
Produce relocatable object file, suitable for another linker pass.
@item -rpath library-search-path
Add a directory to the runtime library search path. This is used
when linking an ELF executable with shared objects. All @option{-rpath}
arguments are concatenated and passed to the runtime linker,
which uses them to locate shared objects at runtime.
@item -S
Strip all debugger symbols from the output.
@item -s
Strip all symbols from the output.
@item -sc
Merge all code sections to a single code section.
@item -sd
Merge all data and bss sections to a single data-bss section.
@item -set-adduscore
Start adding a preceding underscore for the symbols of the
following objects in the command line.
@item -set-deluscore
Start deleting a preceding underscore for the symbols of the
following objects in the command line.
@item -shared
Instructs the linker to build a shared object from the object
files rather than a normal executable image.
@item -soname name
Sets the "real name" of a shared object or library. For ELF
this will create the @code{SONAME} tag in the @code{.dynamic}
section.
@item -T script
Specifies a linker script, which defines the absolute
locations for every section. The syntax is very similar
to that used in GNU linker scripts.
Supported commands:
@itemize @minus
@item CONSTRUCTORS
@item ENTRY
@item EXTERN

linker will display a warning.
@item -tos-flags value
Set the 32 bit flags field of the Atari TOS header to @code{value}.
All @option{-tos} options are only valid for the targets ataritos and
aoutmint.
@item -tos-fastload
Sets the fastload bit (0) in the TOS header.
@item -tos-fastram
Sets the fastload bit (1) in the TOS header.
@item -tos-fastalloc

by any process).
@item -tos-super
Sets the flags in the TOS header to mark memory space as read-writeable by
processes in supervisor mode only.
@item -tos-readable
Sets the flags in the TOS header to mark memory space as read-only for other
processes.
@item -u symbol
Marks symbol as undefined in the first section which was
found on the command line. This might trigger linking of
addtional modules from standard libraries.
This is equivalent to the linker script command EXTERN.
@item -V version
Minimum major version of shared object to be linked.
@item -v
Prints @command{vlink} version string, default library search path
and implemented target file formats.
@item -w
Suppress all warning messages.
@item -X

@end table
@section Known Problems
@itemize @minus
@item Neither shared objects nor dynamically linked executables can be
generated for @code{a.out} format.
@item The following options are not really supported:
@option{-S}, @option{-X}, @option{-Bsymbolic}
@item Source level debugging support is missing for some formats.
@item Many linker script commands are still missing.
@item Default linker scripts are mostly missing, so you need to provide
your own script using the @option{-T} option.
@item @code{PHDR} support for ELF is not perfect.
