Subject: [gcc(refs/users/clyon/heads/mve-autovec)] arm: Add tests for PR target/100757
Date: Wed, 12 Jan 2022 08:27:21 +0000 (GMT) [thread overview]
Message-ID: <20220112082721.EEA383858029@sourceware.org> (raw)
https://gcc.gnu.org/g:7912bb5b56689a83323d0b155938ddbc18fc108f
commit 7912bb5b56689a83323d0b155938ddbc18fc108f
Author: Christophe Lyon <christophe.lyon@foss.st.com>
Date: Wed Oct 13 09:15:58 2021 +0000
arm: Add tests for PR target/100757
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.
