Hello David,
Hello Nagaraju,

are there more patches in queue to submit?

I've played a little bit with the new architecture to rebuild the Xilinx
Microblaze toolchains as provided on Git:

  http://git.xilinx.com/?p=microblaze-gnu.git;a=tree;f=binaries 

Unfortunately I run into some issues:

1) Mainstream gcc-4.6.2 doesn't supoorts -mbig-endian/-mlittle-endian
options. The old Petalogix port (gcc-4.1.2) have had added a patch set
for this. I've solved it temporary with a QnD hack in microblaze.sh in
scripts/build/arch: set CT_ARCH_ENDIAN_CFLAG and CT_ARCH_ENDIAN_LDFLAG
empty (grrr, hack hack hack). Here is the gcc error message:

#prompt> touch tt.c
#prompt> microblaze-unknown-linux-gnu-gcc -mbig-endian tt.c
cc1: error: unrecognized command line option '-mbig-endian'

#prompt> microblaze-unknown-linux-gnu-gcc -EB tt.c
microblaze-unknown-linux-gnu-gcc: error: unrecognized option '-EB'

See attachment microblaze-unknown-linux-gnu-gcc--target-help-dump.txt
too.

2) With ./ct-ng libc_start_files I run into eGlibc problems. It tells
me: configure: error: The microblaze is not supported. Does eGlibc
mainline support Microblaze at all?


So it seems some stuff is missing, or not? Can anybody help me or give
me a hint where I can found gcc/eglibc patches (ongoing development
repositories) for Microblaze?
