--- Comment #6 from Fangrui Song <i at maskray dot me> ---
To make sure we are on the same page. In the case that both a.o and a.so define
the common symbol:
The definition from a.o wins. --version-script should apply versions on the
definition. At runtime, the shared object should refer to the executable's
symbol. (This is the regular rule for definitions.)
st_size: largest st_size from all object files and shared objects
alignment: largest st_value (alignment) from all object files and shared
objects
In my pasted example, mpi_fortran_argvs_null_ should have the default version
OMPI_2.0.0 and st_size=8.
Action items:
gold/lld: respect st_size/st_value in shared objects
ld: fix VER_NDX_LOCAL
