ipa/97673 - fix input_location leak
This fixes input_location leaking with an invalid BLOCK from
expand_call_inline to tree_function_versioning via clone
materialization.
2021-01-19 Richard Biener <rguenther@suse.de>
PR ipa/97673
* tree-inline.c (tree_function_versioning): Set input_location
to UNKNOWN_LOCATION throughout the function.
* gfortran.dg/pr97673.f90: New testcase.
