hi folks, i want to use the builtin __sync_val_compare_and_swap on 128 bit datatypes. older versions of ggc always gave me a "incompatible type for argument 1 of '__sync_val_compare_and_swap'", which took as "not supported". now i am using a current version of the compiler, and it does give me a "undefined reference to `__sync_val_compare_and_swap_16", which i dont understand. obviously the compiler does now know about t, but does not fully support it. it does of course work with 64 bit arguments. i sthere anything i need to do? some switch? or link something in? or does this just mean support for it is not yet fully there? thanks robert -- Robert Lemmen http://www.semistable.com
