| From: Nicholas Krause via talk <talk@gtalug.org> | | 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, As I understand the description, it lets you find the hot-spots in the compilation process (i.e. the runtime of an LLVM compiler itself). I admit that the description doesn't make this completely clear. If I'm right, this feature is only useful for LLVM developers.
