No, but insn RTX costs is slightly increased for -fpic. From ix86_rtx_cost():
--cut here--
case SYMBOL_REF:
if (TARGET_64BIT && !x86_64_immediate_operand (x, VOIDmode))
*total = 3;
else if (TARGET_64BIT && !x86_64_zext_immediate_operand (x, VOIDmode))
*total = 2;
else if (flag_pic && SYMBOLIC_CONST (x)
&& (!TARGET_64BIT
|| (!GET_CODE (x) != LABEL_REF
&& (GET_CODE (x) != SYMBOL_REF
|| !SYMBOL_REF_LOCAL_P (x)))))
*total = 1;
else
*total = 0;
return true;
--cut here--
Adding -mbranch-cost=5 to dg-options would remove this failure.
