When handling MS style import libraries (also called short import libraries, or ILF), we need to detect the kind of library. So far, this has been done by looking at the member file names in the import library - in an MS style import library, all the member files for a specific library have the same member file name - the name of the runtime module to link against. Usually this is a DLL - thus we do a case insensitive comparison and check if the suffix is .dll. However, an .exe can also export symbols which can be linked against in the same way. In particular, if linking against WDK (Windows Driver Kit) import libraries, e.g. wdmsec.lib, the import libraries can provide imports for ntoskrnl.exe. Instead of specifically checking for *.dll (and *.exe, etc), invert the condition and skip archive members named *.o and *.obj. For any remaining archive members, that do contain .idata sections, apply the renaming. (The renaming is also mostly harmless if applied where it isn't needed; if archive members already have unique file names, their relative ordering should remain intact except for very contrieved cases.)

README for LD
This is the 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 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 supports 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 supports a control language.
* There is a user manual (ld.texi), as well as the
beginnings of an internals manual (ldint.texi).
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
or using the --with-lib-path configure switch.
To build just the linker, make the target all-ld from the top level
directory (one directory above this one).
Porting to a new target
=======================
See the ldint.texi manual.
Reporting bugs etc
===========================
See ../binutils/README.
Known problems
==============
The Solaris linker normally exports all dynamic symbols from an
executable. The GNU linker does not do this by default. This is
because the GNU linker tries to present the same interface for all
similar targets (in this case, all native ELF targets). This does not
matter for normal programs, but it can make a difference for programs
which try to dlopen an executable, such as PERL or Tcl. You can make
the GNU linker export all dynamic symbols with the -E or
--export-dynamic command line option.
HP/UX 9.01 has a shell bug that causes the linker scripts to be
generated incorrectly. The symptom of this appears to be "fatal error
- scanner input buffer overflow" error messages. There are various
workarounds to this:
* Build and install bash, and build with "make SHELL=bash".
* Update to a version of HP/UX with a working shell (e.g., 9.05).
* Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in
genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the
emulparams script used exports any shell variables it sets.
