[PATCH] kunit: cleanup assertion macro internal variables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All the operands should be tagged `const`.
We're only assigning them to variables so that we can compare them (e.g.
check if left == right, etc.) and avoid evaluating expressions multiple
times.

There's no need for them to be mutable.

Also rename the helper variable `loc` to `__loc` like we do with
`__assertion` and `__strs` to avoid potential name collisions with user
code.
