Preserving tree node fields for access in LTO?

[Uday Khedker]

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.
