[Ada] Disable anonymous allocator warning for library-level objects
This patch modifies the behavior of anonymous allocator warnings so that
they no longer get triggered in the case of an object declaration at
library-level.
2019-08-13 Justin Squirek <squirek@adacore.com>
gcc/ada/
* exp_ch4.adb (Expand_N_Allocator): Add condition to detect
library-level object declarations
gcc/testsuite/
* gnat.dg/anon3.adb, gnat.dg/anon3.ads: New testcase.
