[patch 0/4] Never pollute bfd_usrdata by libbfd (go32)

[patch 0/4] Never pollute bfd_usrdata by libbfd (go32)

[Jan Kratochvil]

Hi,

GDB has regressed now as it expected bfd_usrdata to be NULL:
	[patch] Assertion for a regression by gdb_bfd_unref
	http://sourceware.org/ml/gdb-patches/2009-08/msg00131.html

But it is now in use by i386-unknown-go32:
	bfd/coff-stgo32.c:#define bfd_coff_go32stub bfd_usrdata

It is a problem for --enable-targets=all configurations where the go32 target
gets used to (unsucessfully) check the file format polluting bfd_usrdata.

My only goal was to remove this bfd_usrdata pollution but as I needed to
regression test it I faced various other blocks blocking the testing.

It was regression tested by primary targets listed below.  Only the whole
patchset together was regression tested.

I have no problem dropping the patchset if bfd_usrdata does no longer get
touched by libbfd during --enable-targets=all configurations some other way.


Thanks,
Jan
