--- Comment #1 from UroÅ Bizjak <ubizjak at gmail dot com> ---
The compilation with -maccumulate-outgoing-args avoids the ICE, although the
resulting asm code touches %ebp in frame-related insn:
#(insn/f 16 20 21 2 (set (reg/f:SI 6 bp)
# (reg/f:SI 7 sp)) t.c:6 90 {*movsi_internal}
# (nil))
movl %esp, %ebp # 16 *movsi_internal/1 [length = 2]
