Asm template question: Is there a way to replace these two functions with one function that automatically uses rori when the 2nd argument is a constant known at compile-time? #FollowerPowerpic.twitter.com/TBcW8YEUc7

If you make the wrapper a macro instead of a function you shouldn't need optimization enabled for it to work.
With optimization it just works.
I didn't want to do that because if it's a macro I'll need ({ ... }) if I want to return a value and for some reason I thought it would be a good idea to avoid that, but now I don't quite know why I felt this way because asm templates aren't quite std C either.. ;)

Could avoid the ({...}) trickery with the good 'ol ternary operator...
#define ror(a,b) ( __builtin_constant_p(b) ? _rori(a,b) : _ror(a.b) )Thanks. Twitter will use this to make your timeline better. UndoUndo
