I'm working on structure reorganization optimizations and one of the things that needs to happen is that pointers to arrays of structures need to be modified into either being an integer of a structure depending on which optimization is required.
I'm seeing something similar happening in omp-low.c where the code in install_var_field and fixup_child_record_type both seem to rebuild the entire type from scratch if a field is either added or modified. Wouldn't it be possible simply modify the field(s) in question and rerun layout_type? I suspect the answer will be no but reasons as to why that wouldn't work will probably be equally valuable to me. Thanks, Gary Oblock
