This is a cpu tool for benchmarking the peak performance of floating-points and AI ISAs.
It can automatically sense the local SIMD|DSA ISAs while compiling.

E2K has support for instructions that perform two independant operations. It is like FMA, but with additional rounding as these operations is independant.
fmul_addd src1, src2, src3, dst
Multiply double-precision (64-bit) floating-point values from src1 and src2,
and add the intermediate result to value from src3. Store the result in dst.
dst[63:0] := src3[63:0] + src1[63:0] * src2[63:0]

./cpufp --thread_pool=[xxx] --idle_time=yyy
--thread_pool: [xxx] is the list of cpu thread to benchmarking, from setting affinities. Please reference the result of lstopo command. For example, [0,3,5-8,13-15].
--idle_time: the interval time(sec) between any two adjacent benchmarks, default is 0.
Add armv9(SVE, SVE2 & SME) Supports.
