Bug ID: 112712
Summary: Crash when compiling g++ -m68020-60 -O2
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Preprocessed output
This is a crash which seems to be specific to the -m68020-60 option (or better
said to 060 code generation as the only other option where this bugs occurs is
-m68060). When changing to any other CPU (-m68000, -mcpu=5475, ...) and/or
changing to -O1, -O0, ... everything is fine.
