From: Eric Botcazou <ebotca...@adacore.com>
This fixes a spurious error on an imported function with a precondition
and a parameter declared with a 'Base formal type, and even a crash in
the case where this function is declared in a generic package.
gcc/ada/
* freeze.adb (Wrap_Imported_Subprogram): Use Copy_Subprogram_Spec
to copy the spec from the subprogram to the generated subprogram
body.
(Freeze_Entity): Do not wrap imported subprograms inside generics.
Tested on x86_64-pc-linux-gnu, committed on master.
