Confirmed. Also appears on trunk on an arm-elf cross with the flags:
-O3 -funroll-all-loops -fomit-frame-pointer -mno-apcs-frame -finline-functions
-mfpu=vfp -mfloat-abi=softfp -mcpu=arm926ej-s
We are generating an invalid input reload for
(insn:HI 320 4403 4405 391 (set (mem/s:HI (plus:SI (reg:SI 318 [ ivtmp.1515 ])
(reg/f:SI 1731)) [2 tmp S2 A16])
(subreg:HI (reg:SI 523) 0)) 152 {*movhi_insn_arch4}
(insn_list:REG_DEP_TRUE 319 (nil))
(expr_list:REG_DEAD (reg:SI 523)
(nil)))
Specifically, reload 2 contains:
Reload 2: reload_in (HI) = (mem:HI (plus:SI (mult:SI (reg:SI 11 fp [orig:318
ivtmp.1515 ] [318])
(const_int 2
[0x2]))
(reg/v/f:SI 10 sl
[orig:437 rcoeff_ind ] [437])) [4 S4 A32])
GENERAL_REGS, RELOAD_FOR_INPUT (opnum = 1), can't combine
reload_in_reg: (subreg:HI (reg:SI 523) 0)
reload_reg_rtx: (reg:HI 6 r6)
but that's an invalid memory address for HImode.
