Description Tomas Lindquist Olsen 2008年10月01日 18:48:22 UTC

I can't find anywhere in the spec where it's clarified what can be used as a global/static initializer (only some special cases, like static struct initializers)
for example it's valid to initialize a global with the address of a function, statically. however, for example, it's not allowed to cast this function pointer to an integer even though there's no technical reason this should not be allowed.

Casting a pointer to an int may require halving its size, and the object file format often does not support that.
