Stefan Krah added the comment:
In the following program, with gcc-5.3 doit() is significantly faster than
doit2() in 64-bit Linux:
================================================================
#include <stdint.h>
int
doit(int64_t index, int64_t nitems)
{
return index < 0 || index >= nitems;
}
int
doit2(int64_t index, int64_t nitems)
{
return (uint64_t)index >= (uint64_t)nitems;
}
int
main(void)
{
int count, i;
for (i = 0; i < 1000000000; i++) {
count += doit(832921, i);
}
return count;
}
================================================================
