The line about which the assembler complains:
5958 sethi %hh(A_SUN4V_TLB_TSB_LOCK), %g5
A sparc64 build is in progress, but I expect kernels to fail in the
same way.
The builds are being done starting with completely empty (nonesistent)
$TOOLDIR, $OBJDIR, $DESTDIR $RELEASEDIR.
As the nightly builds are succeeding and the autobuild hosts are
running NetBSD/amd64-6.1.x, I would assume that tools are being mis-
configured on a NetBSD-5 host.
My 'build.sh' command line:
./build.sh -U -m sparc -T /d0/build/current/tools/i386 \
-O /d0/build/current/obj/sparc -D /d0/build/current/DEST/sparc \
-R /d0/build/current/REL -X ../xsrc -x -u -j 2 tools release
>How-To-Repeat:
Using NetBSD-5 host system, attempt to build 6.99.33 sources for sparc
or sparc64 targets.

This is a nice one. The problem is not netbsd-6 as build host vs. netbsd-5,
but a 64bit build host vs. a 32bit one.
Gennassym creates the constant in question as:
assym.h:#define A_SUN4V_TLB_TSB_LOCK 1152921504606846976
while the original definition is:
pte.h:#define SUN4V_TLB_TSB_LOCK 0x1000000000000000UL
I don't remember right now wether there was some special asm syntax to make
gas on 32bit hosts understand 64bit constants (this all sounds like a
gas bug to me).

In the genassym output...
But: I can not reproduce the problem.
I tried sparc64--netbsd-as -32 --warn test.s on this file:
sethi %hh(0x1000000000000000ULL), %o2
sethi %hh(1152921504606846976), %o1
ret
on a 32 bit host, and it creates proper object code without any warning.
Now I'm a bit puzzzled.

Try 32-bit only toolchain (sparc--netbsdelf-as), it causes "bignum
invalid" error.

Ah yes, it does - and for both notations.

it requires both a 32bit-host *and* building 32 bit sparc64 kernels.
eg, build.sh -m sparc kernel=GENERIC_SUN4U on an i386. with that
i get the same problem:
/usr/src/sys/arch/sparc64/sparc64/locore.s: Assembler messages:
/usr/src/sys/arch/sparc64/sparc64/locore.s:5958: Error: bignum invalid
5958 sethi %hh(A_SUN4V_TLB_TSB_LOCK), %g5
i agree with martin earlier in the thread -- binutils problem.

After tracing the binutils source around gas from the error
message, it was found that 32-bit toolchains on 32-bit host cannot
handle 64-bit integer by default configuration (see bfd/bfd-in.h
and integer_constant() in gas/expr.c).
It requires to specify --enable-64-bit-bfd to bfd/configure or add
a hint as below to enable 64-bit integer handling.
So I would like to apply this patch, comment?

I made this change and subsequent release build succeeded. My sparc
kernels, etc. appear to work just fine. I don't currently have any
sun4u machines operational.
Thanks.

Since the SUN4V support is still incomplete a workaround could be to
disable the SUN4V support in the GENERIC_SUN4U config file:
