Dear Dan,

I had big problems compiling a kernel for s/390 on my linux host - I tried
|
|
yann@1
|
10 |
different chains from crosstool-0.28-rc34 and finally succeded with
|
|
yann@1
|
11 |
gcc-3.3.4-glibc-2.3.2 after applying another patch to binutils-2.15
|
|
yann@1
|
12 |
(attached).
|
|

|
13 |
All compilations of the different kernel versions I tried stopped with
|
|
yann@1
|
14 |
"Invalid .insn format" somewhere. I checked the recent cvs version of
|
|
yann@1
|
15 |
binutils and applied the latest diff to gas/config/tc-s390.c and that solved
|
|
yann@1
|
16 |
it.
