re PR tree-optimization/86214 (Strongly increased stack usage)
PR tree-optimization/86214
* tree-inline.h (struct copy_body_data): Add
add_clobbers_to_eh_landing_pads member.
* tree-inline.c (add_clobbers_to_eh_landing_pad): New function.
(copy_edges_for_bb): Call it if EH edge destination is <
id->add_clobbers_to_eh_landing_pads. Fix a comment typo.
(expand_call_inline): Set id->add_clobbers_to_eh_landing_pads
if flag_stack_reuse != SR_NONE and clear it afterwards.
* g++.dg/opt/pr86214-1.C: New test.
* g++.dg/opt/pr86214-2.C: New test.
