Subject: [PATCH v2] tests: use xmalloc to allocate implementation array
Date: Wed, 28 Jul 2021 13:05:30 +0530 [thread overview]
Message-ID: <20210728073530.3917457-1-siddhesh@sourceware.org> (raw)
The benchmark and tests must fail in case of allocation failure in the
implementation array. Also annotate the x* allocators in support.h so
that the compiler has more information about them.
