Hello. Many significant changes has landed in mainline and will be released as GCC 8.1. I decided to use various GCC configs we have and test how there configuration differ in size and also binary size.
This is first part where I measured binary size, speed comparison will follow. Configuration names should be self-explaining, the 'system-*' is built done without bootstrap with my system compiler (GCC 7.3.0). All builds are done on my Intel Haswell machine. Feel free to reply if you need any explanation. Martin
