From: Eric Botcazou <ebotcazou@adacore.com> The front-end now rewrites it as a renaming when it is initialized with a function call and the same processing must be applied in the renaming case as in the regular case for this kind of special objects. gcc/ada/ * gcc-interface/decl.cc (gnat_to_gnu_entity) <E_Variable>: Apply the specific rewriting done for an aliased object with an unconstrained array nominal subtype in the renaming case too. Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/gcc-interface/decl.cc | 12 ++++++++++++ 1 file changed, 12 insertions(+)
