lto alone works and reduces size a bit, also turning on optimizations has a much bigger effect though. Which I suspect happens because gcc detects constant expressions then, calculates them at compile time instead of runtime, which in turn removes function calls in code paths never taken. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
