costan 2964b803b8 leveldb: Fix alignment code in SSE4.2-optimized CRC32C. When faced with a pointer that is misaligned by K bytes (pointer % 8 == K), the code previously moved forward by K bytes. In order to end up with an aligned pointer, the code must move by 8 - K bytes. This lands https://github.com/google/leveldb/pull/488 ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=166295921			7 лет назад

README

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
