Subject: tools/nolibc: use intmax definitions from compiler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
[ Upstream commit e5407c0820ea5fa7117b85ed32b724af73156d63 ]
The printf format checking in the compiler uses the intmax types from
the compiler, not libc. This can lead to compiler errors.
Instead use the types already provided by the compiler.
Example issue with clang 19 for arm64:
nolibc-test.c:30:2: error: format specifies type 'uintmax_t' (aka 'unsigned long') but the argument has type 'uintmax_t' (aka 'unsigned long long') [-Werror,-Wformat]
