This is on AIX/PowerPC. If there is anything else you need to know, please just ask. Caused by: PR rtl-optimization/16356 * config/rs6000/rs6000.md (floatdisf2_internal2): Rewrite with separate output register and one less jump. Enable for powerpc64. (floatdisf2): Adjust for above. Uhh, yes, it's a typo. The (const_int 3) in floatdisf2_internal2 should indeed be (const_int 2). Bootstrapping the obvious fix.

W. (In reply to comment #6) > How about the other branches? 4.0 is frozen right now and you really don't want a 3.4.5 (which sounds like will be released before 4.0.3) to have a fix before 4.0.x has it.
