Hi Bruno,

I apply it against last 2.4.20-pa35 (do not have any more pa22 :( ) (just
2 hunk to remove). Unfortunately it failed to compile with following message:
`gcc-3.0 -print-libgcc-file-name` /usr/src/LKCD/hppa/linux-2.4.20-pa35-lkcd/arch/parisc/lib/lib.a
/usr/src/LKCD/hppa/linux-2.4.20-pa35-lkcd/lib/lib.a  \
	--end-group \
	-o vmlinux
fs/fs.o(.debug_info+0x6fbaf): undefined reference to `.L1225'
make: *** [vmlinux] Error 1

(Sorry I already met this kind of pb but do not remember how to solve :()

Thanks for your undertand,
    Joel

PS: No more support of compression (I tried libz2 but it do not found some
object at ld time)?

At first glance, this would appear to be a GCC bug.  If I was to guess,
it's a problem with a label for a jump table being deleted.

You might be able to avoid the problem by compiling fs.o with a different
optimization.  The problem could be investigated further by generating
the assember output for the routine with -g.  Search for the above label.
The debug information in the file will allow finding the source line.

I will try gcc-3.2 (or later) because

fs.o is in fact a lib build with "ld -r -o fs.o open.o read_rite.o [...]"

and 'objdump -d fs.o' do not actualy help me to find back any above references
:(

Thanks,

It didn't help so I have to come back to you with severall questions:

A. what is your compiler release gcc 3.0 3.2 3.3?

B. I suspect also a different .config: may I ask your to compare with mine?

Thanks again,
    Joel

Well very very different from mine I will so test also on my b2k (but in
32bits and 64bits).

in the mean time I reach to build a kernel 2.4.21-pa32 with gcc-3.2 but I
forget the __c_f_f_c pb so it crash imedieately, I will so go test 2.4.21-pa35
with your patch.

See you later,
    Joel

Hi Bruno,

Continuing my investigation, I reach now (with some known modif) to compile
the kernel with your patch and gcc-3.3 (as it seems that it became the
default in unstable) but to reach to compile dump_lbz2 (as static builtin)
i had to change following stuff into driver/dump/Makefile:

--- Makefile.orig	2003-05-20 14:50:46.000000000 +0200

I do not realy understand make :(

Thanks for advise,
