Subject: [PATCH] Avoid memcpy inline expansion in gcc.dg/out-of-bounds-1.c
Date: Wed, 29 Sep 2021 08:07:23 +0200 (CEST) [thread overview]
Message-ID: <6113sno0-9rn3-r097-4984-qp4911s61q9q@fhfr.qr> (raw)
This avoids inline expansion to preserve the warning by making
the memcpy size a non-power-of-two as suggested by Martin Sebor.
Tested on x86_64-unknown-linux-gnu, pushed.

* gcc.dg/out-of-bounds-1.c: Make memcpied size not power-of-two.
