Subject: Patch for cross compiling s/390 kernel on linux host
Date: Tue, 31 Aug 2004 15:45:41 +0200
Dear Dan,
I had big problems compiling a kernel for s/390 on my linux host - I tried
different chains from crosstool-0.28-rc34 and finally succeded with
gcc-3.3.4-glibc-2.3.2 after applying another patch to binutils-2.15
(attached).
All compilations of the different kernel versions I tried stopped with
"Invalid .insn format" somewhere. I checked the recent cvs version of
binutils and applied the latest diff to gas/config/tc-s390.c and that solved
it.
Greetings
Michael Geiger
