Greetings.
I have been chasing down a binutils regression that is preventing me from
building a Linux/MIPS kernel using a gcc-4.2 based toolchain. Here is the
snippet of output when building a 2.6.12 kernel for my platform:
LD drivers/mtd/maps/built-in.o
LD drivers/mtd/nand/built-in.o
LD drivers/mtd/built-in.o
mipsel-linux-uclibc-ld: final link failed: Bad value
make[1]: *** [drivers/mtd/built-in.o] Error 1
make: *** [_module_drivers/mtd] Error 2
The versions were:
binutils-2.17.50.0.12
gcc-4.2-20070131
linux-headers-2.6.12
Using the release version of binutils-2.17 works fine and does not
produce the error above. However, binutils-HEAD out of today's CVS
and all of H.J. Lu's development releases > 2.17.50.0.3 will produce
the error. The regression appeared in binutils-2.17.50.0.4 and still
exists. The simple patch is:
--- binutils-2.17.50.0.12/bfd/elfxx-mips.c
+++ binutils-2.17.50.0.12-patched/bfd/elfxx-mips.c

++relocation;
I applied to binutils-HEAD and was then able to build a valid Linux/MIPS
kernel and applications. I need to move on to other items, but if someone
could comment or have a look at this, it would be much appreciated. If a
better formatted bug report should be submitted somewhere, just let me
know. Thanks.
