[GTALUG] ftrace-time support in Clang

Greetings, This seems to be a rather not know option on the LLVM side and it seems GCC does not support it. https://www.phoronix.com/scan.php?page=news_item&px=LLVM-Clang-9.0-Time-Trace Its now in mainline as the articles like this one were mostly written before it was merged in clang/llvm version 9. 10 was just released so its now in the mainline. Maybe it interests some people here who build large software products or use embedded build systems, Nick
