/*
* When BR_SSE2 is enabled, SSE2 intrinsics will be used for some
* algorithm implementations that use them (e.g. chacha20_sse2). If this
* is not enabled explicitly, then support for SSE2 intrinsics will be
* automatically detected. If set explicitly to 0, then SSE2 code will
* not be compiled at all.

/*
* When BR_POWER8 is enabled, the AES implementation using the POWER ISA
* 2.07 opcodes (available on POWER8 processors and later) is compiled.
