Subj: 	Problems with tcr1supportos.nightly

Hi,

Sorry, but I was out at a customer last week, and apparently noone has done
anything else with this...

I talked with Andy Duane who mentioned a problem with ld that can cause 
"hundreds" of "branch relocation out of range" errors if there is a multiply
defined, or undefined, symbol.  In looking at the logs for the failed build
on Sept 25, I noticed that there are two undefineds at the beginning of the
hard errors.  When I build GENERIC in my sandbox, I do not have this problem.
The only error message I get is in rm_spur where it does complain about the
branch relocation being out of range, but successfully builds a GENERIC kernel
with the trampoline code.

Here is the beginning of tcr1supportos.nightly/Logs/Error.summary:

kernel.bld.log:4569:Error: Undefined:
kernel.bld.log:4932:Error: Undefined:
kernel.bld.log:4449:cnx_hab_cfg.o: branch relocation out-of-range, bad object 
file produced, can't branch from 0xfffffc000064b8b4 to 0xfffffc000023f66c
kernel.bld.log:4572:mcs_asalloc.o: branch relocation out-of-range, bad object 
file produced, can't branch from 0xfffffc0000663184 to 0xfffffc00002450fc
.
.
.

I have no idea where the undefineds are coming from.  Could someone figure
out why we get them?  Again, I do NOT get these errors when I build the
kernel, so I suspect that a header file, or something, is being left off in
the build environment.

Also, tcr1supportos.nightly does not appear to have any cscope information.
Could someone please fix this?

Thank-you,

Rob Marshall

The cscope databases get pushed to nightly when the nightly gets pushed, which 
is when it's successful, which this hasn't been for a while. For your 
convenience, I pushed the failed build's cscope database to nightly.

I looked for the two undefined symbols and found they were both in:
kernel/kern/lockinfo.c - ONLY.

So far this pool has only taken in these files:

./kernel/rm/ccomsub.c,v 1.1.17.2
./kernel/rm/ccomsub.h,v 1.1.16.2
./kernel/io/drd/drd_drv.c,v     1.1.7.2
./kernel/rm/rm_error.c,v        1.1.8.2
./kernel/rm/rm_kern.c,v 1.1.17.2

Hope this helps a little in your analysis.
