Subject: [PATCH 02/13] 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.
Ok, but I'd rather it was committed together with the patch that fixes the ICE.
I don't mind if it's a separate commit or rolled into that patch.
Sure, I'll wait for the main patch approval. I split it this way to
hopefully make the reviews easier, to exercise the testcase without the
fix proposal.
Thanks,
Christophe
