Hmm, I cannot reproduce this on hppa-linux. Weird.

You need a LP64 platform to host the compiler.

David, can you have a look at this report please? It would be great if you 
could at least confirm this, and check if it is a regression or not. Thanks.

hppa--netbsd isn't a supported configuration (i.e., it's not in config.gcc).
Thus, this isn't a regression.

Questions on doing a port should be addressed to the gcc list.

The rtl should look like:

(insn 10 9 11 0 00000000 (set (reg:DI 96)
        (high:DI (const_int 60486 [0xec46]))) -1 (nil)
    (nil))

(insn 11 10 12 0 00000000 (set (reg:DI 95)
	(lo_sum:DI (reg:DI 96)
	    (const_int 60486 [0xec46]))) -1 (nil)
    (expr_list:REG_EQUAL (const_int 60486 [0xec46])
	(nil)))

Dave

OK, closing as invalid then, since it does not affect any supported/released 
version of GCC.
