[llvm-dev] -ftime-report with LTO?

[Sjoerd Meijer via llvm-dev]

Quick query on option -ftime-report (while I am further investigating): is that supposed to work in combination with LTO? It doesn't seem to do anything, but perhaps I am doing something wrong.

Thanks.

IIRC that flag is propagated to none of the LTO options (ThinLTO, gold plugin, LLD).

However I feel like it's a good idea to do so. Feel free to send a patch.
