This commit adds the -Wformat-signedness compiler flag to detect and prevent printf format errors, where signed or unsigned types are mismatched with format specifiers. This helps to catch potential issues at compile-time, ensuring that our code is more robust and reliable. With this flag, the compiler will now warn about incorrect format strings, such as using %d with unsigned types or %u with signed types. Signed-off-by: Jiayuan Chen <[email protected]>
Fixed some formatting specifiers errors, such as using %d for int and %u for unsigned int, as well as other byte-length types. Perform type cast using the type derived from the data type itself, for example, if it's originally an int, it will be cast to unsigned int if forced to unsigned.
