which toolchain version for Microblaze

[Stephan Linz <linz at li-pro dot net>]

Hi Michal,
Hi David

which version of binutils and gcc you are currently using for embedded
Linux development? Just now I've played a little bit with the new one
I've found in the Xilinx git repository on:

git://git.xilinx.com/microblaze-gnu.git

Unfortunately both the binaries and the sources seems to be buggy. When
I try to compile U-Boot with it the final linker stage runs into a
SIGSEGV -- here is the (reduced) output:


UNDEF_SYM=`microblaze-unknown-linux-gnu-objdump -x
board/xilinx/microblaze-generic/libmicroblaze-generic.o api/libapi.o

**/*.o | sed  -n -e 's/.*\(__u_boot_cmd_.*\)/-u\1/p'|sort|uniq`;

@David: This error can be reproduced with the binaries in Xilinx git
repo. Have you any idea?

@Michal: which version did you use currently?

@all: Is there anybody who can give me a hint how I can / should handle
this error?



br,
Stephan
