Joey, this is caused by ix86_get_drap_rtx:
/* Assign DRAP to vDRAP and returns vDRAP */
unsigned int regno = find_drap_reg ();
rtx drap_vreg;
rtx arg_ptr;
rtx seq;
arg_ptr = gen_rtx_REG (Pmode, regno);
crtl->drap_reg = arg_ptr;
start_sequence ();
drap_vreg = copy_to_reg (arg_ptr);
seq = get_insns ();
end_sequence ();
emit_insn_before (seq, NEXT_INSN (entry_of_function ()));
return drap_vreg;
Do we really need vDRAP?
