static defgv #397

Open rurban opened 8 years ago

rurban commented 8 years ago

about 50% of SVOP run-time init consists of svop_list[%d].op_sv = (SV*)PL_defgv; converting PL_defgv to be static with a protected (IMMORTAL) refcount would decrease run-time init a lot.

need to check if any init before the compiler init uses the dynamic PL_defgv pointer.
override global destruction for PL_defgv.
