Is this a debug log or normal from now on during a ghc build? I don't mind, but I just wanted to make sure it's not a mistakenly enabled debug flag somewhere.
It is a normal flag and was present long ago on build system: mk/config.mk.in: GhcHcOpts=-Rghc-timing but happened to break a couple of releases ago. Was fixed in https://ghc.haskell.org/trac/ghc/ticket/8787
You can disable it by putting GhcHcOpts= in mk/build.mk.
I see.
