Preserving tree node fields for access in LTO?



We have added a new field (bool ptr_arith in struct tree_base) to the tree node. We are assigning values to this field in a gimple pass in non-LTO mode and would like to access them in LTO mode in our ipa passes. It appears that all fields of tree node are not preserved in LTO mode. Is there any way to tell GCC that a given field should be preserved so that it can be accessed in LTO mode?

Thanks and regards,

Uday.
