Do we test with clang on any of the sparc64-linux systems? If freebsd uses
the integrated assembler of clang, that might help.
On gcc202, it seems that we first hit that clang doesn't like -mptr64, so
I remove it for testing. I need to add -fintegrated-as so it does not use
the external GNU binutils. And finally I get
tmp-gcd_11.s:206:6: error: unexpected token

(and related errors for tmp-bdiv_q_1.s tmp-mode1o.s tmp-invert_limb.s etc)
Compiling an example C file with -S, where gcc produces things like
sethi %gdop_hix22(tab), %g1
xor %g1, %gdop_lox10(tab), %g1
ldx [%l7 + %g1], %l7, %gdop(tab)
with clang I only see
sethi %hi(tab), %i2
add %i2, %lo(tab), %i2
