Only two of those accesses remained in the fast loop, because the rest were hoisted up and out of the loop. There are no less than five chained (pointer-chasing) memory accesses. Since it’s a standalone function call, it has to do more work. Enjoy our collection of ASCII ART, ASCII Tables and other interactive tools.

Here’s what that looks like on my system:

The loop itself is one instruction shorted, but of course you need to run all the code inside toupper as well. The slow version, on the other hand, leaves the toupper() inside the loop. So now the assembly makes sense: the fast version of the algorithm inlines the toupper body, but it can’t inline the _ctype_toupper_loc() call 9 however, this call is declared _attribute_((const)) which means that its return value depends only on the arguments (and here there are no arguments) and so the compiler knows it returns the same value every time and so can be hoisted out of the loop, so the loop body has only a few loads associated with the lookup table, the store of the new value to the buffer, and loop control 10. That function returns a thread-local pointer (a const int **), which in turn points to a lookup table which given a character returns the uppercase version 8. Dont forget to click the spacesunderscores button to fill the white space with underscore characters so that when you paste it somewhere, it doesnt collapse all the spaces.

We see that toupper is implemented as an extern inline function that first checks that the range of the char fits within a byte 7 and then looks up the character in the table returned by _ctype_toupper_loc().
