Compiler inconsistently handles multiple definitions of a global variable in different files with and without link time optimization

XMLWordPrintable

    • Type: Bug
    • Resolution: Unresolved
    • Priority: Low

      The attached files each contain this variable definition ...

      void *global_handle;

      Build it with no optimization ...

      % armcl -mv7m4 -mt -me f1.c f2.c -z -o f.out
[f1.c]
[f2.c]
<Linking>

      ... a clean build results. Build it with link time optimization ...

      % armcl -mv7m4 -mt -me -o4 f1.c f2.c -z -o f.out
[f1.c]
[f2.c]
<Linking>
error: symbol "global_handle" has already been defined
