[COMMITTED] ada: Remove useless validity suppression for attribute Input
Checks
Commit Message
From: Piotr Trojanek <trojanek@adacore.com>
Attributes 'Input and 'Read are similar, but only the 'Read denotes a
subprogram with parameter of mode OUT where operand validity checks need
to be suppressed.
Cleanup related to fix for attributes 'Has_Same_Storage and
'Overlaps_Storage.
gcc/ada/
* exp_attr.adb (Expand_N_Attribute_Reference): Remove useless
skipping for attribute Input.
Tested on x86_64-pc-linux-gnu, committed on master.
