Thanks.

Here's an example from Building clang with ThinLTO: F10296420: clang-10.json <https://reviews.llvm.org/F10296420>

Using linker flags: -Wl,-time-trace -Wl,-time-trace-granularity=50000

I increased the granularity from the default, otherwise the trace gets very large (~800MiB).

> Speaking of the output file, I'd make --time-trace option to take an output filename, as an output executable doesn't always have an extension (On Windows it's almost always .exe, but on Unix, extension is usually omitted).

Okay. I'll look at doing that.
