ada: Fix memory explosion on aggregate of nested packed array type
It occurs at compile time on an aggregate of a 2-dimensional packed array
type whose component type is itself a packed array, because the compiler
is trying to pack the intermediate aggregate and ends up rewriting a bunch
of subcomponents. This optimization was originally devised for the case of
a scalar component type so the change adds this restriction.
gcc/ada/
* exp_aggr.adb (Is_Two_Dim_Packed_Array): Return true only if the
component type of the array is scalar.
