/*

Artificially create _GLOBAL_AIX[ID]_shr_o symbols in libgcc.a.
|
|
|
|
This means that libstdc++.a can invoke these symbols and they are resolved
|
|
regardless of whether libstdc++.a is linked against libgcc_s.a or libgcc.a.
|
|
|
|
The symbols are created in libgcc_s.a by collect2 as there are exception
|
|
frames to register for LIB2_DIVMOD_FUNCS.
|
|
|
|
The symbols are NOT created by collect2 for libgcc.a, because libgcc.a is
|
|
a 'real' archive containing objects and collect2 is not invoked.
|
|
|
|
libstdc++.a is linked against libgcc.a when handling the command line
|
|
options '-static-libgcc -static-libstdc++'.
