san19	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:<br /> - Comparing the code-size of clang and gcc for bare metal programs on M-profile devices.<br /> - Adding Arm support to the LLVM machine outliner.<br /> - Adding C++ virtual function elimination to Clang.<br /> - Building zephyr using GCC LTO.<br /> 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.	featured path true /assets/images/featured-images/san19/SAN19-403.png	2	SAN19-403	Sunset 3 (Session 3)	end_time start_time 2019-09-26 08:55:00 2019-09-26 08:30:00	speaker_bio speaker_company speaker_image speaker_location speaker_name speaker_position speaker_url speaker_username Peter is an Assignee to the Linaro Toolchain team (TCWG) working on LLVM based tools, specializing in Linkers.
