57 # bits = 64/32 --- -DIS_64BIT --- 64-/32-bit operating system
58 # prefetch = yes/no --- -DUSE_PREFETCH --- Use prefetch x86 asm-instruction

61 # popcnt = yes/no --- -DUSE_POPCNT --- Use popcnt x86_64 asm-instruction
62 # sse = yes/no --- -msse --- Use Intel Streaming SIMD Extensions
64 # Note that Makefile is space sensitive, so when adding new architectures
65 # or modifying existing flags, you have to make sure there are no extra spaces
