void * allocate (const Options & Options, uptr Size, uptr AlignmentHint, uptr * BlockEnd, FillContentsMode FillContents)

As with the Primary, the size passed to this function includes any desired

alignment, so that the frontend can align the user allocation. The hint

parameter allows us to unmap spurious memory when dealing with larger

(greater than a page) alignments on 32-bit platforms.

Due to the sparsity of address space available on those platforms, requesting

an allocation from the Secondary with a large alignment would end up wasting

VA space (even though we are not committing the whole thing), hence the need

to trim off some of the reserved space.

For allocations requested with an alignment greater than or equal to a page,

the committed memory will amount to something close to Size - AlignmentHint

(pending rounding and headers).
