--- Comment #3 from Uroš Bizjak  ---
Actually, gcc can now handle misaligned stack for x86_64 and it emits 

{
  rtx unspec = gen_rtx_UNSPEC (mode, gen_rtvec (1, reg), UNSPEC_STOREU);
  insn = emit_insn (gen_rtx_SET (mem, unspec));
}

that is later decorated with:

add_reg_note (insn, REG_CFA_EXPRESSION, gen_rtx_SET (mem, reg));

So, i386_pe_seh_unwind_emit has to be updated to handle REG_CFA_EXPRESSION.

C source

According to ChangeLog, ktietz is the one who modified this since it was last
working (verified on 26 Sept. 2015).  There are hundreds of failures pointing
to the same source line, between build and test suite.
