Subject: [PATCH v2 nolibc 04/15] tools/nolibc: add libc-test binary
Date: Thu, 18 May 2023 07:55:10 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <4817a4dc-69e6-4937-84d5-f2f630ff646c@paulmck-laptop>
From: Thomas Weißschuh <[email protected]>
This can be used to easily compare the behavior of nolibc to the system
libc.
