--- Comment #9 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
This is ugly issue indeed, I will look more into it tomorrow.
Optimally of course we should be able to handle -fPIC per symbol basis, but
that is hard to do. I guess having it handled via ix86_option_override_internal
is not a bad temporary plan.
Out of the options lto-wrapper handles, I think the following can be now
dropped:
case OPT_fexceptions:
case OPT_fnon_call_exceptions:
case OPT_fshort_double:
case OPT_fmath_errno:
case OPT_fsigned_zeros:
case OPT_ftrapping_math:
case OPT_fwrapv:
case OPT_ftrapv:
case OPT_fstrict_overflow:
case OPT_foffload_abi_:
case OPT_O:
case OPT_Ofast:
case OPT_Og:
case OPT_Os:
But that can probalby wait for stage1, they are harmless (I would not be
affraid to drop them now)
I think I missed the following in my weekend's common.opt update. It should be
Optimization.
case OPT_fpcc_struct_return:
case OPT_ffp_contract_:
I however think there are couple other options that may be wroth merging, like
-fdata-sections that does not go via optimization machinery.
