re PR fortran/45777 (Alias analysis broken for arrays where LHS or RHS is a component ref)
2011-01-08 Thomas Koenig <tkoenig@gcc.gnu.org>
PR fortran/45777
* symbol.c (gfc_symbols_could_alias): Strip gfc_ prefix,
make static and move in front of its only caller, to ...
* trans-array.c (symbols_could_alias): ... here.
Pass information about pointer and target status as
arguments. Allocatable arrays don't alias anything
unless they have the POINTER attribute.
(gfc_could_be_alias): Keep track of pointer and target
status when following references. Also check if typespecs
of components match those of other components or symbols.
