--- Comment #7 from acsawdey at gcc dot gnu.org ---
I just pulled that sms branch from 

https://github.com/ispras/gcc-sms.git

and built it on ppc64le. sms-4 does not do any better than with trunk, we still
have the problem of incorrectly labeling it as possibly infinite in
loop_doloop:

Loop 1 is simple: 
  simple exit 5 -> 6 
  infinite if: (expr_list:REG_DEP_TRUE (ne:SI (and:DI (minus:DI (plus:DI
(ashift:DI (reg:DI 211)
                        (const_int 2 [0x2]))
                    (reg/v/f:DI 205 [ ap ]))
                (reg:DI 193 [ ivtmp.20 ]))
            (const_int 3 [0x3])) 
        (const_int 0 [0]))
    (nil))

This inhibits doloop conversion and then sms cannot take place either.

What arch did you test where sms-4 passed, amonakov?
