Why does GCC generate such radically different assembly for nearly the same C code?

...e(). I'll spare you the assembly, but it is identical - register names and all. Step 2: Mathematical reduction: x + (y ^ x) = y sign can only take one of two values, 0 or 0x80000000. When x = 0, then x + (y ^ x) = y then trivial holds. Adding and xoring by 0x80000000 is the same. It flips the sign...

“static const” vs “#define” vs “enum”

...sion for static arrays at function scope; both (2) and (3) can. Under C99, all of these can be used for local arrays. Technically, using (1) would imply the use of a VLA (variable-length array), though the dimension referenced by 'var' would of course be fixed at size 5. (1) cannot be used in place...
