I'd first like to understand why Paul chose to override the generic
versions of these macros. There is a change in what you map to:
__sync_val_compare_and_swap -> __sync_val_compare_and_swap_1/2/4/8
__sync_add_and_fetch -> __sync_add_and_fetch_1/2/4/8
Were there any problems with the _N variants on some ARM compilers ?
The non-"_N" variants do not exist outside the back-end (they are mapped
to the "_N" variants by target-independent parts of the compiler), but I
agree that Paul's ack is good to have.
