This is a BETA release of a completely rewritten GNU linker.
|
||
|
|
It is distributed with other "binary utilities" which should
|
||
|
|
be in ../binutils. See ../binutils/README for more general notes,
|
||
|
|
including where to send bug reports.
|
||
|
|
|
||
|
|
There are many new features of the linker:
|
||
|
|
|
||
|
|
* The linker uses a Binary File Descriptor library (../bfd)
|
||
|
|
that it uses to read and write object files. This helps
|
||
|
|
insulate the linker itself from the format of object files.
|
||
|
|
|
||
|
|
* The linker support a number of different object file
|
||
|
|
formats. It can even handle multiple formats at once:
|
||
|
|
Read two input formats and write a third.
|
||
|
|
|
||
|
|
* The linker can be configured for cross-linking.
|
||
|
|
|
||
|
|
* The linker contains a control language.
|
||
|
|
|
||
|
|
* There is a manual.

Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
See ../binutils/README.
|
||
|
|
If you want to make a cross-linker, you may want to specify
|
||
|
|
a different search path of -lfoo libraries than the default.
|
||
|
|
You can do this by setting the LIB_PATH variable in ./Makefile.
|
||
|
|
|
||
|
|
Porting to a new target
|
||
|
|
=======================
|
||
|
|
|
||
|
|
A new target configuration may need a new linker script (.sc file)
|
||
|
|
to specify linker actions (such as the layout of the output).
|
||
|
|
See if one of the existing ones are suitable.
|
||
|
|
Note that the Makefile generates variants of the standard script
|
||
|
|
that are used when ld is passed -r -Ur -N or -n options.
|
||
|
|
These variant default scripts are generated from the "master"
|
||
|
|
script using sed scripts that may not work in all cases.
|
||
|
|
Look at the rules and comments in ld/Makefile.in to make sure
|
||
|
|
you stay with the rules.
|
||
|
|
|
||
|
|
Otherwise, you may need to add a new "emulation" (a sample of a
|
||
|
|
recently added target and emulation is for the SOny 68k News
|
||
|
|
family - look for files named *news*).
|
||
|
|
|
||
|
|
Also see the notes in ../binutils/README.
