Bug #: 53766
Summary: ICE in build_binary_op when using pragma Suppress
(All_Checks)
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: baldrick@gcc.gnu.org
At a guess, the code that inserts runtime checks adds a need type conversion
that is forgotten when checks are suppressed. I see this with gcc-4.7 and
with mainline.
$ gcc-4.8 -c p.adb

The expanded code without -gnatp looks quite different.

* exp_attr.adb (Expand_N_Attribute_Reference): Add local variables Attr
and Conversion_Added. Add local constant Typ.
Retrieve the original attribute after the arithmetic check
machinery has modified the node. Add a conversion to the target
type when the prefix of attribute Max_Size_In_Storage_Elements
is a controlled type.
