constantdivisionbenchmarks

Benchmarks for constant-division problems (not a library! for research only!)

Prerequistes

• A bash shell and a Linux-like system.
• It helps to have the GCC and clang compilers installed. The scripts that ends with gcc.sh require GCC whereas the scripts that ends with clang.sh require clang.
• Some specific tests require a Linux machine with a working perf command, but most tests run fine on other operating systems. You can generally install perf on Linux with commands such as sudo apt-get install linux-tools or sudo apt-get install linux-perf.

Usage (requires just a working compiler)
