-/**
- Skip trailing space.
-
- On most systems reading memory in larger chunks (ideally equal to the size of
- the chinks that the machine physically reads from memory) causes fewer memory
- access loops and hence increased performance.
- This is why the 'int' type is used : it's closest to that (according to how
- it's defined in C).
- So when we determine the amount of whitespace at the end of a string we do
- the following :
- 1. We divide the string into 3 zones :
- a) from the start of the string (__start) to the first multiple
- of sizeof(int) (__start_words)
- b) from the end of the string (__end) to the last multiple of sizeof(int)
- (__end_words)
- c) a zone that is aligned to sizeof(int) and can be safely accessed
- through an int *
- 2. We start comparing backwards from (c) char-by-char. If all we find is
- space then we continue
- 3. If there are elements in zone (b) we compare them as unsigned ints to a
- int mask (SPACE_INT) consisting of all spaces
- 4. Finally we compare the remaining part (a) of the string char by char.
- This covers for the last non-space unsigned int from 3. (if any)
-
- This algorithm works well for relatively larger strings, but it will slow
- the things down for smaller strings (because of the additional calculations
- and checks compared to the naive method). Thus the barrier of length 20
- is added.
-
- @param ptr pointer to the input string
- @param len the length of the string
- @return the last non-space character
