-Subject: [PATCH] Avoid cast of address constant to integer constant in
- initalizer
-Upstream: https://mailman.astron.com/pipermail/file/2019-December/000247.html
-
-RCAST converts an address constant to an integer, and then to pointer. An
-integer constant cast to a pointer type is a valid address constant,
-however, a pointer cast to a integer is not an integer constant:
-
-> Cast operators in an integer constant expression shall only convert
-> arithmetic types to integer types, except as part of an operand to the
-> sizeof operator.
-
-So the result of RCAST(const void *, zlibcmp) is not technically a
-constant expression, and might be rejected by some compilers when it is
-used in an initializer for an object with static storage.
-
-Instead, just use a union so no casts are necessary.
