Dear List,
This may also be off-topic and maybe I have missed this if it was
covered earlier in the discussion but could someone explain to dumb
little me why it is not possible to mark Objective-C methods as
inline ? I do understand the way the runtime works and see several
simple modifications to even late bound code that would allow this to
function correctly and be used in some cases for significant
performance optimisations.
TIA
Vince

Speaking of inline, what is the difference (if any) between
__inline, __inline__, and __attribute__((always_inline))? Looking at
the definitions of CF_INLINE, I see:
#if defined(__GNUC__) && (__GNUC__ == 4) && !defined(DEBUG)
#define CF_INLINE static __inline__
__attribute__((always_inline))
#elif defined(__GNUC__)
#define CF_INLINE static __inline__
#elif defined(__MWERKS__) || defined(__cplusplus)
#define CF_INLINE static inline
#elif defined(_MSC_VER)
#define CF_INLINE static __inline
#elif defined(__WIN32__)
#define CF_INLINE static __inline__
#endif
Why this header using __inline__ __attribute__((always_inline)) for
gcc 4.x?
Both C++98 and C99 include an inline keyword and they seem to be
about the same--as opposed to how gcc, at least, treats inline in
C89 vs. C99. Is there a reason to use __inline or __inline__ (both
of which do work with gcc) instead of inline?
I know these questions aren't really appropriate for Xcode-users and
I apologize, but there is still no more appropriate list. (I filed a
bug a year ago requesting the creation of such a list but was told
that that was the wrong place to do so but that my feedback had been
forwarded to "the appropriate group for review & consideration.")
