New Revision: 3570
Modified:
trunk/osprey/ipa/main/optimize/ipo_struct_opt.cxx
Log:
This change affects the existing "array remapping" optimization by adding a
restriction to exclude arrays with non-zero field_id (e.g., arrays that are
themselves members of structs) from being considered as array remapping
candidates.
Approved by Min Zhao.
Modified: trunk/osprey/ipa/main/optimize/ipo_struct_opt.cxx
