[issue28397] Faster index range checks

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

In your example functions are inlined. If prohibit inlining, the second function is faster.

$ gcc -O3 -o issue28397 issue28397-2.c 
$ time ./issue28397 0

real    0m8.097s
user    0m7.992s
sys     0m0.012s
$ time ./issue28397 1

real    0m5.467s
user    0m5.436s
sys     0m0.024s
