Session Abstract

For many projects that use resource constrained devices, optimizing for the smallest code-size is often more important than optimizing for the highest performance. The TCWG team would like to share their progress and results on several code-size related projects. These include:
- Comparing the code-size of clang and gcc for bare metal programs on M-profile devices.
- Adding Arm support to the LLVM machine outliner.
- Adding C++ virtual function elimination to Clang.
- Building zephyr using GCC LTO.
The presentation will give a brief summary of how the clang and gcc compilers compare on code-size, and a description of some improvements you can expect in future versions of the compilers.
