(This is filed as PR toolchain/28065 in the NetBSD gnats database)

When crosscompiling a NetBSD/hppa kernel on a NetBSD/sparc64 host, the compiler
fails in various files. On example of the error message is:

/usr/src/src/sys/netinet6/nd6.c: In function `nd6_setmtu0':
/usr/src/src/sys/netinet6/nd6.c:230: error: unrecognizable insn:
(insn 34 33 35 6 0x40cc94a0 (set (reg:DI 97)
        (plus:DI (reg:DI 103)
            (const_int -5056 [0xffffffffffffec40]))) -1 (nil)
    (expr_list:REG_DEAD (reg:DI 103)
        (nil)))
/usr/src/src/sys/netinet6/nd6.c:230: internal compiler error: in
extract_insn, at recog.c:2175

The compiler configuration is:
