--- Comment #5 from Joel Hutton <joel.hutton at arm dot com> ---
There's some problem with inserting an OI before an OI, which requires an OI
before it etc.
18: r98:OI=r99:OI
REG_DEAD r97:V4SI
Inserting insn reload before:
19: r99:OI=r97:V4SI#0
0 Non input pseudo reload: reject++
alt=0,overall=13,losers=2,rld_nregs=4
0 Non pseudo reload: reject++
alt=1,overall=7,losers=1,rld_nregs=2
0 Non input pseudo reload: reject++
1 Spill pseudo into memory: reject+=3
Using memory insn operand 1: reject+=3
alt=2,overall=19,losers=2 -- refuse
Choosing alt 1 in insn 19: (0) Utv (1) w {*aarch64_movoi}
Creating newreg=100, assigning class FP_REGS to r100
19: r99:OI=r100:OI
Inserting insn reload before:
20: r100:OI=r97:V4SI#0
