but the decision whether to use them is made at compile time,
based on compiler-defined macros.
To use NEON instructions, add "-mfpu=neon" to CFLAGS.
PowerPC: No runtime CPU detection.
To use AltiVec instructions, add "-maltivec" to CFLAGS.
x86: The miner checks for SSE2 instructions support at runtime,
and uses them if they are available.
x86-64: The miner can take advantage of AVX, AVX2 and XOP instructions,
