What does multicore assembly language look like?

I didn't annotate it, mostly because it is so similar to the machine code generated by the C# program. The printf() functi...
How do you set, clear, and toggle a single bit?
... string with the bitwise NOT operator (~), then AND it.
Toggling a bit
The XOR operator (^) can be used to toggle a bit.
number ^= 1UL << n;
That will toggle the nth bit of number.
Checking a bit
You didn't ask for this, but I might as well add it.
To check a bit, shift the number n to the ri...

...tute all with an explicit axis.
What about other operations, like logical_xor? Again, same deal… except that in this case there is no all/any-type function that applies. (What would you call it? odd?)

Why does C++ rand() seem to generate only numbers of the same order of magnitude?
