Rui Ueyama 7c8fc8142e MemoryBlock: Do not automatically extend a given size to a multiple of page size. ... Previously, MemoryBlock automatically extends a requested buffer size to a multiple of page size because (I believe) doing it was thought to be harmless and with that you could get more memory (on average 2KiB on 4KiB-page systems) "for free". That programming interface turned out to be error-prone. If you request N bytes, you usually expect that a resulting object returns N for `size()`. That's not the case for MemoryBlock. Looks like there is only one place where we take the advantage of allocating more memory than the requested size. So, with this patch, I simply removed the automatic size expansion feature from MemoryBlock and do it on the caller side when needed. MemoryBlock now always returns a buffer whose size is equal to the requested size. Differential Revision: https://reviews.llvm.org/D56941 llvm-svn: 351916		2019-01-23 02:03:26 +00:00
