The new tests ICE on i686-linux:
FAIL: gcc.dg/builtin-complex-err-1.c (internal compiler error)
FAIL: gcc.dg/builtin-complex-err-2.c (internal compiler error)
FAIL: gcc.dg/torture/builtin-complex-1.c -O* (internal compiler error)
All the ICEs are on
case EXCESS_PRECISION_EXPR:
/* Each case where an operand with excess precision may be
encountered must remove the EXCESS_PRECISION_EXPR around
inner operands and possibly put one around the whole
expression or possibly convert to the semantic type (which
c_fully_fold does); we cannot tell at this stage which is
appropriate in any particular case. */
gcc_unreachable ();
in c_fully_fold_internal.
