The reason that we're rejecting the "m" alternative is that we've expanded
"+mr"(blen) to
(set (reg/v:SI 60 [ blen.25 ])
(asm_operands:SI ("") ("=mr") 2 [
(mem/i:SI (plus:SI (reg/f:SI 16 argp)
(const_int 16 [0x10])) [0 d+0 S4 A32])
(reg/v/f:SI 65 [ a ])
(reg/v/f:SI 67 [ b ])
(reg/v:SI 68 [ blen ])
Note reg 60 as output and reg 68 as input. Probably out-of-ssa is
missing the fact that we'd like these variables to be unified.
