Control globalization of file static variables but not functions.
Globalization is a technique needed by fix and continue and interprocedural optimization whereby file static symbols are promoted to global while a prefix is added to the name to keep identically named symbols distinct.
The default is -xglobalize=no. Specifying -xglobalize is equivalent to specifying -xglobalize=yes.
See -xpatchpadding.
-xipo requires globalization as well and will override -xglobalize.
