------- Comment #11 from burnus at gcc dot gnu dot org 2010-07-16 09:11 -------
Seemingly, we currently only "recycle" DECLs for procedure decls, but not for
module variable decls.
Looking at
gfortran -fdump-tree-optimized-all -O3 char_array_structure_constructor.f90
one finds (grep MOD_c):
__global_MOD_cD.1586
__global_MOD_cD.1606
However, if one removes the second "USE global" and uses the host-associated
variable, it works (i.e. there is only one "__global_MOD_cD").
Expected: The same DECL is used for host associated variables - and, at least
with -fwhole-file, the same DECL is used for the whole file.
I wonder whether the same problem also exists for COMMON symbols.
(Note: While the wrong-code only becomes apparent on x86_64-apple-darwin10, the
bug itself exists on all platforms. Thus, I have emptied the PR's target
field.)
