Subject: [PATCH v2 02/14] arm: Add tests for PR target/100757
Date: Wed, 13 Oct 2021 12:15:22 +0200	[thread overview]
Message-ID: <20211013101554.2732342-3-christophe.lyon@foss.st.com> (raw)
In-Reply-To: <20211013101554.2732342-1-christophe.lyon@foss.st.com>

These tests currently trigger an ICE which is fixed later in the patch
series.

The pr100757*.c testcases are derived from
gcc.c-torture/compile/20160205-1.c, forcing the use of MVE, and using
various types and return values different from 0 and 1 to avoid
commonalization with boolean masks.  In addition, since we should not
need these masks, the tests make sure they are not present.
