Subject: [PATCH v2 09/16] tools/nolibc: add limits.h shim header
Date: Wed, 26 Feb 2025 12:44:48 +0100 [thread overview]
Message-ID: <20250226-parse_vdso-nolibc-v2-9-28e14e031ed8@linutronix.de> (raw)
In-Reply-To: <20250226-parse_vdso-nolibc-v2-0-28e14e031ed8@linutronix.de>
limits.h is a widely used standard header.
Missing it from nolibc requires adoption effort to port applications.
Add a shim header which includes the global nolibc.h header.
It makes all nolibc symbols available.
