Can we stick the following somewhere in the code:
#define ARRAYSIZEOF(x) (sizeof(x) / sizeof((x)[0]))
and use it instead of that underlying expression? I use this macro in
my projects frequently, but I always wonder if it could be #include'd
from a standard header. Anyway, to take your example one step further:
#define JTAG_ADD_PATH_EXCEPTIONS(x) \
jtag_add_pathmove(ARRAYSIZEOF(x), x);
then:
JTAG_ADD_PATH_EXCEPTIONS(exception_path);
Cheers,
