What are the mechanics of short string optimization in libc++?
...nt architectures?
In the short form, there are 3 words to work with:
1 bit goes to the long/short flag.
7 bits goes to the size.
Assuming char, 1 byte goes to the trailing null (libc++ will always store a trailing null behind the data).
This leaves 3 words minus 2 bytes to store a short string...
maximum value of int
...estion but maybe someone can use this solution:
int size = 0; // Fill all bits with zero (0)
size = ~size; // Negate all bits, thus all bits are set to one (1)
So far we have -1 as result 'till size is a signed int.
size = (unsigned int)size >> 1; // Shift the bits of size one position to ...
