The IRA dump says:
  a2(r189,l0) costs: AREG:2000,2000 DREG:2000,2000 CREG:26000,-1000
BREG:2000,2000 SIREG:2000,2000 DIREG:2000,2000 AD_REGS:2000,2000 CLOBBERED_REGS
:2000,2000 Q_REGS:2000,2000 TLS_GOTBASE_REGS:2000,2000 GENERAL_REGS:2000,2000
SSE_FIRST_REG:12000,12000 NO_REX_SSE_REGS:12000,12000 SSE_REGS:12000,
12000 ALL_SSE_REGS:12000,12000 MMX_REGS:26000,26000 INT_SSE_REGS:26000,26000
ALL_REGS:424000,424000 MEM:12000,12000
so the INT_SSE_REGS cost of 26000 seems might higher than GENERAL_REGS cost.
