Extremely Simple Microbenchmarks

To build X86 binaries,

make

To build ARM binaries,

make ARM

To build RISCV binaries,

make RISCV

To build X86, ARM, and RISCV binaries,

make all

To set the path to X86 compiler, change $CC_X86 in make.config file.
To set the path to ARM compiler, change $CC_ARM in make.config file.
To set the path to RISCV compiler, change $CC_RISCV in make.config file.

The binaries are named bench.X86, bench.ARM, and bench.RISCV on each subdirectory.

From the original README file,

Hi,

This is an extremely simple microbenchmark suite.

Its intended purpose is in the validation of general purpose out-of-order
cores, by targetting individual micro-architectural features or effects.
Of course this is by no means an exhaustive collection of necessary bencharks
to test every mechanism in an OOO processor. This is merely a starting point.

To use this, you should only need bash, make and python.

Configure the versions of the compiler and python (tested with python-2.7):

vim make.config

To make the benchmarks:

make

Clean the benchmarks:

make clean

Describe basically what each benchmark is for:

describe.sh

Run a benchmark: (no args on any current benchmark)

cd CCa
./test

PS: Also, some benchmarks use an LFSR setting to get a particular working set.
Please see lfsr_settings.txt for example values. (bench ML2 uses this)
