We start with a large address and need to discard a large number of the bits to generate a block ID which is within range. But how do we choose the unique bits of the address versus those which are the same for every block? The high bits of -the address may simply be all `0s` or all `1s` to make the address canonical, -the middle portion of the address may be the same for all blocks (since if they -are all within the same binary, then they will all be adjacent in memory), and -on some systems, even the low bits may have poor entropy as some use fixed -length aligned instructions. Then we need to consider that a portion of each -binary may contain the `.data` or `.bss` sections and so may not contain any -blocks of code at all. +the address may be all `0s` or all `1s` to make the address canonical, the +middle portion of the address may be the same for all blocks (since if they are +all within the same binary, then they will all be adjacent in memory), and on +some systems, even the low bits may have poor entropy as some use fixed length +aligned instructions.
