17 Helper macros used for setting different __attributes__
18 on functions in a portable fashion
21 #ifndef _my_attribute_h
22 #define _my_attribute_h
25 Disable __attribute__() on gcc < 2.7, g++ < 3.4, and non-gcc compilers.
26 Some forms of __attribute__ are actually supported in earlier versions of
27 g++, but we just disable them all because we only use them to generate
31 # if !defined(__GNUC__)
32 # define __attribute__(A)
33 # elif GCC_VERSION < 2008
34 # define __attribute__(A)
35 # elif defined(__cplusplus) && GCC_VERSION < 3004
36 # define __attribute__(A)
41 __attribute__((format(...))) is only supported in gcc >= 2.8 and g++ >= 3.4
42 But that's already covered by the __attribute__ tests above, so this is
43 just a convenience macro.
45 #ifndef ATTRIBUTE_FORMAT
46 # define ATTRIBUTE_FORMAT(style, m, n) __attribute__((format(style, m, n)))
51 __attribute__((format(...))) on a function pointer is not supported
54 #ifndef ATTRIBUTE_FORMAT_FPTR
55 # if (GCC_VERSION >= 3001)
56 # define ATTRIBUTE_FORMAT_FPTR(style, m, n) ATTRIBUTE_FORMAT(style, m, n)
58 # define ATTRIBUTE_FORMAT_FPTR(style, m, n)
59 # endif /* GNUC >= 3.1 */
