LLVM libc has been steadily growing over the past few years. From its origins as an overlay to be used on top of an existing libc, LLVM libc is now complete enough and scalable enough to be used on embedded toolchains too.

This talk will contain: * LLVM libc's current status. * Why you might want to use LLVM libc. * How to build it for linux and an embedded system. * How to use a prebuilt example from LLVM Embedded Toolchain for Arm. * Other uses including the Google Pigweed SDK.
