Subject: [REPORT] [GSoC - TCG Continuous Benchmarking] [#6] Performance Comparison of Two QEMU Builds
Date: Mon, 27 Jul 2020 12:30:00 +0200

Hi everyone,

The sixth report of the TCG Continuous Benchmarking project presents a
performance comparison between two different QEMU builds, GCC and Clang.

The report also presents five new benchmarks to allow for a variety of
test workloads. Each of the five benchmarks is executed for seventeen
different QEMU targets on both the GCC and Clang builds.

The resulting ten tables are then summarized then analyzed using the
list_helpers.py and list_fn_callees.py scripts. The entire workflow is
automated using Python scripts that are posted in the report.
