(In reply to H.J. Lu from comment #3)
> It was caused by r217655.
The problem was introduced earlier when function_code field in
tree_function_decl was extended to 12 bits. LTO streamers were not fixed
appropriately. r217655 increased BUILT_IN_COMPLEX_MUL_MIN value and put it out
of 11 bits which revealed the problem.
With this patch compiles OK:
